Il progetto “Laboratorio Sistema Madonie” strumento per la conservazione e la valorizzazione del germoplasma locale

Florintesa, a program agreement for the italian botanical gardens and the national floristic heritage.

OUR CLAIM: "The Botanical Gardens are, par excellence, responsible for carrying out the important mission of the conservation of our flora, through specific actions on live plants and their seeds, along with education and outreach aimed at spreading a new environmental culture, more careful and respectful of the essential needs of life, more sensible to the aesthetic and scientific value of the national flora" To overcome the isolation and strengthen their role in our society, the University Botanical Gardens have become promoters of national and European consortiums: examples are the working group "Botanical and Historic Gardens" of the Italian Botanical Society (1) and, on the global leve…

Chemical composition of the essential oils of Centaurea sicana and C. giardinae growing wild in Sicily

The essential oils of Centaurea sicana (S) and C. giardinae (G) were studied by GC and GC-MS. Thirty constituents for S, representing 81.5% of the total oil, and 24 compounds for G (94.2% of the total) were identified. The oils were rich in sesquiterpenoids (47.9% for S and 54.7% for G) and hydrocarbons (25.9% for S and 31.7% for G). Germacrene D (13.3%), ( E)-β-farnesene (8.3%), nonacosane (7.3%), heptacosane (6.5%) and phytol (6%) were recognized as the main constituents for S, while caryophyllene oxide (17.7%), nonacosane (14.5%), germacrene D (11.5%), caryophyllene (11.2%) and heptacosane (10.3%) were the main compounds for G.

Phytochemical characterization and antioxidant activity of the aerial part extracts from two species of Matthiola wild in Sicily: Matthiola sinuata and M. tricuspidata (Brassicaceae)

As part of a project aimed at investigating the specific and intraspecific taxa of Matthiola which grow spontaneously in Sicily (Italy), in this work our research has been focused on Matthiola tricuspidata and Matthiola sinuata. The phenolic and volatile compounds of the hydroalcoholic extracts from the aerial parts of the selected species have been characterized by HPLC-PDA/ESI-MS and SPME-GC/MS analyses. Moreover, the antioxidant capacity in vitro (1,1-diphenyl-2-picrylhydrazil (DPPH), reducing power and Fe2+ chelating activity assays) and the toxicity (Artemia salina lethality bioassay) of the extracts were investigated. The phytochemical analyses highlighted quite different phenolic and…

Michele Lojacono-Pojero’s Centuriae in the herbaria and archives in Geneva

Lojacono, well known as the author of a Flora sicula, offered for sale and distributed various exsiccata. In particular, he prepared 7 Centuriae of Plantae siculae rariores (1879-1884) and 4 Centuriae of Plantae italicae selectae (1885-1888). Swiss botanists (Barbey, Boissier, Burnat) were among his first customers. From their legacy, printed, mostly autographic inventories of all but one of these Centuriae (with only the second Italian Centuria missing) came to the archives of the Conservatoire botanique in Geneva, some in two different versions. These rare documents have been dated with the aid of mail stamps and of correspondence kept in the same archives, and transcripts of all of them …

Chemical composition of essential oil from Italian populations of Artemisia alba Turra (Asteraceae).

The use of essential oils as chemotaxonomic markers could be useful for the classification of Artemisia species and to caracterize biodiversity in the different populations. An analysis of the chemical composition of four essential oils from Italian populations of Artemisia alba Turra (collected in Sicily, Marche and Abruzzo) was investigated. In this paper an in depth study of the significant differences observed in the composition of these oils is reported.

Piante invasive e ripercussioni su paesaggio e beni architettonici: il caso di Ailanthus altissima (Simaroubaceae)

L’espansione di specie vegetali invasive sembra essere legata al diffuso degrado ambientale del territorio – da anni sottoposto a una forte pressione antropica – e alla contestuale caduta di barriere geografiche che ha prodotto spostamenti di espressioni floristiche particolarmente aggressive nelle più diverse direzioni. Ai vari livelli, il fenomeno è sottostimato malgrado costituisca un grande pericolo per l’integrità del paesaggio, per il contesto urbano, i giardini storici e i siti monumentali all’aperto; esso, indirettamente, rappresenta anche una minaccia per la biodiversità sottraendo spazio alle specie più sensibili e modificandone l’habitat.

Preliminary insights into the molecular barcoding data of Turraea socotrana (Meliaceae) from Socotra (Yemen)

The relationship of two geographically and ecologically separated populations of Turraea socotrana Styles and F. White (Meliaceae), a vulnerable and scattered shrub from the island of Socotra (Yemen), was explored using preliminary molecular data. The nuclear ribosomal ITS region was used to screen the level of genetic divergence of T. socotrana from ecologically distant localities in comparison to a few other species of Turraea and closely related genera. The individuals from the inland (Diksam) differed from the western coastal ones (Ma’alah) by vegetative characters and by the rbcL gene. This may be due to the fact that the population from Ma’alah grows on lithosoil slopes directly expos…

From ethnobotany to experimental research: the therapeutic properties of Sicilian hellebore

In Sicily, the genus Helleborus (Ranuculaceae) is only represented by H. bocconei subsp. siculus (= H. bocconei subsp. intermedius). In some mountain areas of the Island, the rhizomes of this plant, harvested in a particular month of the year (May) and dried, are used in traditional veterinary practice for treating pneumonia in domestic animals, cattle and horses in particular. The same usage – with rhizomes of other Helleborus species or subspecies – is reported from various other areas of Mediterranean Europe. Phytochemical tests have permitted the isolation and characterization of new biologically active molecules. The extracts of rhizomes and aerial parts of the plant were shown antibac…

First results on the phenotypic analysis of wild and cultivated species of Pyrus in Sicily

Phenotypic analysis of Pyrus in Sicily using a set of 19 characters on 71 accessions belonging to 7 species is here reported. Results show a high level of morphological variation in this genus. Cluster analysis of the morphological characters allows to identify two groups: the first closely related to wild pears and the latter related to P. communis s. l. and P. sicanorum. It is likely to think that many Ethno-Varieties, usually attributed to P. communis, on the contrary are attributable to wild Sicilian pears and belong to indigenous germplasm.

Isoetes todaroana, a new species from western Sicily (Italy), is described. Morpholog- ical, anatomical and ecological characters are given. The main differential characters are the presence of only two leaf air chambers, rather than four as in all other known species of the genus, and the shape of the scales, which have two lateral rounded lobes and one central spine-like lobe, together with its peculiar calcophilic habitat. So far, the species is known from a single locality.

Genetic diversity in Sicilian populations of Quercus ilex (Fagaceae)

Assessment of the environmental quality of the Sicilian coast through a phytoecological and biogeographic analysis

Large-scale habitat measurements have been aided greatly by advances in remote sensing and GIS software. However, the degree of resolution of this technique is still inadequate for many purposes, such as detail monitoring of many habitats that occur on the coast (e.g. temporary Mediterranean pools or ephemeral therophytic grasslands). Lists and distribution mapping of taxa are probably the most commonly used surrogate for overall biodiversity at both local and broader scales. For the Sicilian coasts a complete study, dating back more than 25 years ago and based on a multidisciplinary approach of flora, vegetation and fauna, exists (Raimondo & al. 1990. Quad. Bot. Amb. Appl. 1: 131-182).…

At the intersection of cultural and natural heritage: Distribution and conservation of the type localities of Italian endemic vascular plants

Abstract We conducted a GIS spatial analysis with the aim of providing the first quantitative large-scale overview of the distribution patterns of 1536 type localities ( loci classici ) of 1216 Italian endemic vascular plants and their relationship with a set of descriptive variables. Whereas some variables were used to model the presence-absence distribution patterns of the type localities for the whole set of endemics as well as for the subset of narrow endemics, others (e.g., presence inside or outside protected areas and Italian Important Plant Areas) were considered with the purpose of assessing potential assets or risks for conservation. The largest number of type localities was found…

Does genetic population structure of Ambrosina bassii L. (Araceae, Ambrosineae) attest a post-Messinian land-bridge between Sicily and Africa?

Abstract Aim of the present work is the analysis (through the study of enzyme polymorphism) of Sicilian and African (Tunisian) populations of Ambrosina bassii , a small perennial endemic to the Central-Western Mediterranean basin, in order to verify if the complex geological history of this part of the Mediterranean area left its mark in the present-day genetic structure of this taxon. Starch gel allozyme electrophoresis of seven putative loci of A. bassii was employed to estimate genetic diversity, genetic structure and gene flow. Populations from Sicily, Tunisia and Sardinia (as outgroup) were sampled. Results show that Sicily populations have 4 private alleles, Sardinia 3, Tunisia just o…

Morphological, karyological and taxonomic remarks on Ferulago nodosa (L.) Boiss. (Apiaceae)

Abstract Western (Sicilian) and eastern (Balcan-aegean) populations of the Balcan-tyrrhenian Ferulago nodosa are reported to be different in some morphological characters, and were considered different species by some authors in XIX century. In this work, fruit and pollen morphologies have been compared in Sicilian and Cretan plants; also, the chromosome number of Sicilian plants has been ascertained. Preliminary results highlight a general homogeneity between the two populations, nevertheless showing significant differences in some parameters (fruit form, pollen size). For this reason, and considering the geographic disjunction of the Sicilian plants, the two populations are proposed to be…

Critical forms in Sicilian populations of annual Lysimachia L. (Primulaceae)

Based on recent literature, in the Primrose family the genus Lysimachia L. absorbed Anagallis L. (1). As a result, new name combinations have been introduced for this genus, thus involving the increase of specific and intraspecific taxa (for Italian flora see 2 and 3). A further consequence, focused in this contribution, concerns the binomial combination Lysimachia arvensis (L.) U.Manns & Anderb., which has different synonyms and includes several specific and intraspecific taxa. As far as the taxonomic history of the annual taxa of Anagallis is concerned, different authors preferred to include some of them in A. arvensis and in A. foemina at the level of variety (4) or subspecies (2), w…

Ecophysiology of germination in Sicilian population of Ferula communis (Umbelliferae)

Ferula communis L. is an umbelliferous plant widespread in the Mediterranean basin and particularly abundant in Sicily and Sardinia islands (Italy). In this species, two chemotypes have been distinguished: one is poisonous and responsible of hemorrhagic syndrome of livestock, known as ferulosis, while the other one (non- poisonous) has anticancer activity due to the presence of daucane esters. In Sicily the dry stem of this plant has commercial applications in special manufactured products. The object of the research was to investigate the germination ecophysiology of nine Sicilian populations of F. communis, in order to establish the correct germplasm conservation of the chemotypes economi…

Genetic diversity and local population structure in Ambrosina bassii (Araceae, Ambrosineae), a Mediterranean relict species

The effects of habitat fragmentation on the genetic structure of Ambrosina bassii are analyzed. The species, whose reproductive biology is mostly unknown, is the only representative of its genus and tribe and it is endemic to the central Mediterranean area. The selected study area was the island of Sicily, in which wild populations show a wide morphological variability and ecological amplitude. Patterns of within- and among-population genetic diversity in eleven Sicilian populations, occurring in six disjunct areas, were examined by means of allozyme electrophoresis. High levels of genetic diversity were found as shown by the mean expected heterozygosity (He ¼ 0.263), the percentage of poly…

Diversity in the population of Brassica incana Ten. (Cruciferae) in Sicily

henotipic diversity in Sicilian populations of Brassica incana Ten. (Cruciferae) is here ana- lyzed in comparison with the only one known population of B. raimondoi Sciandrello et al., taxonomic close species recently described from the coastal relief of eastern Sicily. The analysis of diagnostic characters of these two taxa does not reveal significant differences that justify a treatment at species level of the population of B. raimondoi. On this base, the authors deemed to include this taxon in the infraspecific variability of B. incana and consider most appropriate the rank of subspecies. Therefore is here proposed the establishment of the trinomial com- bination B. incana subsp. raimond…

Assessing the genetic diversity ofCentaurea parlatorisgroup (sect.Dissectae, Compositae) in Sicily using isozymes

Abstract The Centaurea parlatoris group belongs to sect. Dissectae and is one of the most taxonomically critical groups in Sicily. The taxa included in it inhabit dry slopes, pastures and rocky places. Some of them are narrow endemics to Sicily, and others to Italy. The great morphological variability at the intrapopulation level has not permitted the creation of an adequate taxonomic scheme. The recent proposal of two new species from Sicily confirms the insufficient knowledge of the taxonomic diversity. This study involves eight Sicilian populations of the C. parlatoris group. Seven loci from nine enzyme systems [isocitrate dehydrogenase (IDH), malate dehydrogenase (MDH), 6-phosphoglucona…

Molecular and taxonomic characterization of a endophytic fungus isolated from Helleborus bocconei subsp. intermedius (Ranunculaceae)

A non-sporulating fungus was isolated from different organs of Helleborus bocconei subsp. intermedius (Ranunculaceae) endemic to southern Italy and Sicily, known for the traditional use of dried roots in the treatment of lung diseases of cattle and horses. Molecular characterization of endophytic fungus based on the internal transcribed spacer (ITS) region of the rRNA gene sequences was done. The DNA sequence of full length ITS region of the studied fungus was a 100% match to that of Chaetomium strumarium strain dH 21642 (GenBank accession number JX280851.1). The morphological characters of colony and mycelium of this microfungus are reported here.

The Herbarium of Antoine Bras (1803-1883)

Bras, distinguished French amateur botanist and author of a catalogue of the flora of his home province (département de l’Aveyron), built a considerable personal herbarium through 50 years of active collecting (1833-1882). That herbarium, long believed lost, was auctioned in 2008 and acquired by the first author for the Palermo Herbarium (PAL-Gr). Its c. 25,000 specimens are being mounted and databased, with a view of making the digital images and label data available for online consultation. An analysis based on a first sample of 1550 specimens is presented, with explanations of Bras’ labelling and numbering systems and a list of other collectors and correspondents (81 to date) who contrib…

Results of efforts made for in situ and ex situ conservation of Abies nebrodensis (Pinaceae) in Sicily

Detection of ephemeral genetic sub-structure in the narrow endemic Abies nebrodensis (Lojac.) Mattei (Pinaceae) using RAPD markers

A. nebrodensis (Nebrodi fir, Sicilian fir) is restricted to a small area of the Madonie Natural Park in Sicily. According to recent estimates, its only population consists of 30 adult individuals and a fluctuating number of juveniles derived from natural regeneration; besides, some hundreds of cultivated plants are preserved as ex situ collection. We used RAPD data from six 10-mer primers to examine the consequences of extensive historical clearance and human pressures on the extant population. Data from multiple life stages and different habitat conditions were considered, affording an opportunity to ascertain for the first time the structure of genetic variation in the extant uneven-aged …

COMPOSITION OF THE ESSENTIAL OILS IN CALENDULA SUFFRUTICOSA (ASTERACEAE) FROM SICILY

The genus Calendula L. (Calenduleae Cass., Asteraceae) includes several species having medicinal properties. Pharmacological studies reveal, for instance, that C. officinalis L. exhibits antibacterial, antiviral, antinflammatory, antitumor and antioxidant properties; C. arvensis L. has antibacterial, antinflammatory, antimutagenic and haemolytic activities; C. suffruticosa Vahl has antimicrobial activity, especially against pathogenic microorganisms as Pseudomonas syringae Van Hall, Pseudomonas fluorescens (Flügge) Migula, Xanthomonas campestris (Pammel) Dowson and Agrobacterium tumefaciens Smith & Townsend. Nevertheless, despite a long tradition of use of the above species, and others,…

Nomenclatural and taxonomic remarks on Prunus cupaniana (Rosaceae) from Sicily

“Prunus cupaniana” is a nomen nudum doubtfully given by Gussone (1842) to some Sicilian populations close to Prunus mahaleb L. from which they are distinct by both biological and ecological characters. This name was later cited by Nyman (1878) which did not provide its validation, contrary to the erroneous IPNI report “Prunus cupaniana Guss. ex Nyman -- Consp. Fl. Eur. 1: 213. 1878 [Sep 1878]“. Fiori (1926) applied the Gussone’s epithet to the infraspecific combination “Prunus mahaleb cupaniana(Guss.)”, which is invalid being based on a nomen nudum. Before Fiori, Lojacono (1891) treated the same populations under P. mahaleb var. prostrata. Recently Raimondo & Spadaro [in Fl. Medit. 19: 309 …

Lista Rossa IUCN della Flora Italiana. 1. Policy Species e altre specie minacciate

As part of the Mediterranean global biodiversity hotspot, the Italian flora is particularly rich of species, many of them endemic to restricted territories. In some areas of Italy endemic plant species reach very high percentages, between 13% and 20% of the local flora. However, plant diversity in the Mediterranean Basin is facing several threats due to changes of the current socio-economic dynamics. Italy is not an exception and urgent conservation measures are needed to halt the loss of biodiversity and preserve the numerous threatened species. This volume is the output of a project started in 2012, funded by the Italian Ministry of Environment for the Protection of Land and Sea and carri…

Taxonomic remarks on Isatis tinctoria (Brassicaceae) from Pollino National Park (Basilicata, Italy)

Isatis L. (Brassicaceae) is an Eurasian genus including 79 species (1). It is one of the most difficult cruciferous genera (2). Some species, in fact, are highly polymorphic in fruit morphology, the structures that provide the most diagnostic characters (3). In addition, due to the extreme variability in all morphological characters, the limits of many species are uncertain (4). Most if not all diagnostic characters used in earlier classifications are very variable and because of the unreliability of vegetative and floral characters it is difficult or impossible to identify many specimens when mature fruits are missing (5). The patterns of variation suggest that hybridisation may be widespr…

The monophyly and evolution of Cynara L. (Asteraceae) sensu lato: evidence from the Internal Transcribed Spacer region of nrDNA

The monophyly and evolution of Cynara was investigated using ITS sequence data. Parsimony analysis supports the monophyly of Cynara sensu lato, i.e. including the distinctive taxa C. humilis and C. tournefortii. This contradicts the recent decision to create a new monotypic genus Arcyna for C. tournefortii. A hypothesised close relationship between C. tournefortii and Silybum Adans. is also refuted. Four of the five species of Cynara, for which multiple accessions were sequenced, were shown to be monophyletic but C. baetica was found to be non-monophyletic. Free energy estimates for ITS1 secondary structure and conservation of the 5.8S region suggest that this is not due to the occurrence o…

G.I.S. context analysis for environmental recovery suitability evaluation

The attributes of every single patch in a land mosaic constitute the database that landscape ecologists use for processing and analysis. Nonetheless spatial and ecological relationships between adjacent patches can play a key role in understanding the overall functionality of land mosaics. Defining the ecological role of a single tessera within an ecosystem is not possible if that patch is regarded as an insular element; on the other hand global analysis on the entire land mosaic would grant just a small amount of new information on each tessera and none on its functional role. To recognize areas susceptible of improvement through environmental recovery and to define priorities for interven…

Lycopodiidae for the “Flora Critica d’Italia”: material and methods

Procedures are presented that were followed during the preparation of the first pteridophyte family treatments for the “Flora Critica d’Italia”: Lycopodiaceae, Isoetaceae, Selaginellaceae. The work was mainly based on the study of literature and herbarium specimens. In some cases SEM observation of spores has proved useful. Data collected from herbarium specimens and other verified sources were loaded into a database, from which a distribution map was prepared for each taxon. Several preliminary papers have been published, and for each family a taxonomic conspectus, with type designations, maps and an identification key, has been prepared. The treatment of these three families for the “Flor…

Essential oil composition and antibacterial activity of Anthemis mixta L. and Anthemis tomentosa L. (Asteraceae)

In the present study the chemical composition of the essential oils from aerial parts and roots of Anthemis mixta L. and A. tomentosa L. was evaluated by GC and GC-MS, and their antibacterial activity tested against ten bacterial species. Hexadecanoic acid (15.2%) was recognized as the main constituent of A. mixta, together with τ-cadinol (6.7%), while in both aerial parts and roots of A. tomentosa nonacosane (21.9% and 20.7%), heptacosane (8.1% and 6.0%), hexadecanoic acid (8.1% and 27.1%) and hexahydrofarnesylacetone (6.8% and 5.5%) prevailed. The oils from aerial parts of both species showed a good activity against Gram-positive bacteria. These results suggest that the plants could be po…

Development of Sicilian bean core collection using morphological descriptors

Different species and varieties of bean, spread in Sicily, are representative of local agricultural practices, as result of a careful exploration. Many landraces have become obsolete due to the spread of commercial varieties, but are still cultivated in small areas of Nebrodi Mountains (ME-Italy) and are endangered. The Sicilian bean landraces are often poorly known but represent a genetic heritage to be preserve and to enhance. The ex situ conservation of Sicilian bean landraces was carried out in “Living Plants Germplasm Bank” of Ucria (ME-Italy), founded by the Nebrodi Regional Park, and in “Sicilian Plant Germplasm Repository” of STEBICEF Department - University of Palermo. Within ex si…

Protection and conservation of the manna ash landscape in Sicily

Known as manna ashes, some local varieties of Fraxinus ornus L. and F. angustifolia Vahl (Oleaceae) are cultivated for extracting the manna, a product rich in mannose which is useful under both pharmaceutical and nutraceutical aspects. As wild plants in Sicily these ashes participate in diversifying evergreen and deciduous oak woods as well as other forest communities at the watercourse borders, together with several species of Salix, Populus and Ulmus, particularly in the hills. Cultivation of manna dates back to ancient times in Sicily and elsewhere and ash groves were increasingly spread up to the half of last century. Then, the culture had a progressive decline due to the abandonment of…

On the presence, distribution and conservation status of Lycopodium lagopus (Lycopodiaceae) in Italy

During our work on the Lycopodiaceae account for the upcoming Flora Critica d’Italia (1, 2), we assessed and accepted the presence in Italy of Lycopodium lagopus (Laest. ex Hartm.) Zinserl. ex Kuzen. = L. clavatum subsp. monostachyon (Grev. & Hook.) Selander (2). Already reported by Fiori (3) as L. clavatum f. monostachyum Desv., its presence in Italy was more recently confirmed by Tribsch & Schönswetter (4) and accepted in some subsequent regional works (e.g. 5, 6), but the taxon is not recognized as distinct in the last national checklist of vascular plants (7). Lycopodium lagopus has an arctic-alpine distribution in America and Eurasia (8, 9). Initially described as a variety of L. clava…

Mediterranean island biogeography: Analysis of fern species distribution in the system of islets around Sicily

The aim of this article was to test the way in which geographical factors influence island floras in the Mediterranean basin, using ferns as target organisms, and the islands surrounding Sicily as location. A matrix with presence/absence data concerning fern taxa in the 16 islands studied was compiled. Cluster analysis, principal co-ordinates analysis (PCoA), principal components analysis (PCA) and a Bayesian analysis were performed. For each island, the total number of fern taxa was regressed against three factors: island area, island elevation and isolation. All the analyses pointed to affinities between islands according to their different geological composition, independently from their…

Ambienti umidi effimeri e naturalità del paesaggio in Sicilia

I luoghi umidi temporanei sono ambienti acquatici che alternano periodicamente una fase d’invaso ed una fase secca ed ospitano espressive fitocenosi adattate a queste peculiari condizioni. Indagini condotte tra il 2003 ed il 2009 hanno consentito di individuare, in Sicilia, oltre 200 siti, costituiti generalmente da diverse pozze o piccoli stagni. L’estrema fragilità di questi habitat li rende molto vulnerabili a qualunque tipo di alterazione ambientale e pertanto risultano essere indicatori molto sensibili della pressione antropica sul territorio. Infatti, la conservazione di questi biotopi non può prescindere da una corretta gestione del contesto territoriale che li circonda. Il presente …

Typification of Sicilian Helichrysum (Compositae) revisited

Typification of the 13 validly published, pre-1958 names of Helichrysum taxa based on Sicilian material is reassessed. Five of the types designated by Galbany-Casals & al. in their recent studies are confirmed (in some cases with additional precision), two neotypes proposed by them are superseded by lectotypes, and six lectotypes are newly designated. The correct name of the species known as H. rupestre, an illegitimate name, is H. panormitanum (or, if taken in a wide sense, H. pendulum).

Contributo alla conoscenza floristica dei monti Sicani (Sicilia): resoconto dell’escursione del Gruppo di Floristica (S.B.I.) nel 2012

The results of the excursion of the “Gruppo di Floristica” of the Italian Botanical Society held in the Sicani Mountains (CW-Sicily) on May 3-6, 2012, are here presented. During the research a total of 532 taxa was recorded. Three of them, the native Rosa squarrosa and the alien Phyllostachys aurea and Vitis ×koberi are new to Sicily, and 14 are new to the Sicani Mts. On the other side, we confirm the exclusion of Erica manipuliflora from the flora of the region.

Metabolites from the aerial parts of the Sicilian population of Artemisia alba Turra

Phytochemical investigation of the CH2Cl2 extract of the aerial parts of Artemisia alba Turra afforded one new irregular sesquiterpenoid, artemiric acid, and five known metabolites: hydroxydavanone, the coumarins isofraxidin and scopoletin, (6S*,7S*,10R*)-6,10-dimethyl-7,10-epoxyocta-11-enoic acid and artalbic acid. From the MeOH extract three flavonoids were identified: chrysoeriol, quercetin and isorhamnetin. The possible biogenetic pathways of artemiric and artalbic acids are discussed.

Applicazione dell’analisi tridimensionale negli studi di Ecologia del paesaggio

Topography and terrain morphology play a key role in landscape structure and functionality. Landscape ecology modelling based on patch-corridor-matrix usually analyzes the area of study as a plane surface. However, this assumption could be critically far from reality, especially in mountainous areas, and lead to significant mistakes in calculation. Different areas of study were analyzed using both classical and more recent indices. Calculation was performed using a bi-dimensional terrain model and a three-dimensional model in which length and surface area values were much closer to real world values. Results were confronted to understand the different sensitivity of various analysis tools t…

The contribution of forest restoration to the conservation of woody endangered species in Sicily

Sicilian forest ecosystems are, in general, numerically poor in terms of their floristic composition. As many studies on Sicilian dendroflora have highlighted, such poorness is not intrinsic to forest formations, but it is due to the millenary human pressures. Repeated passage of fire, continuous wood usage and reforestations by single or few species dra- matically reduced the plant biodiversity of Sicilian forest ecosystems, often suffering of monodominance. The Sicilian dendroflora includes several endangered species, such as Abies nebrodensis, Betula aetnensis, Celtis tournefortii subsp. asperrima and subsp. aetnensis, as the wild pears, which in Sicily are represented by 4 endemic speci…

In the above cited note, the specific characters as well as the taxonomic relationships with other taxa were highlighted. At the same time, the location of a small population of C.…

The role of phanerogams and cryptogams in the recolonization of cork oak forests crossed by wildfire in Sicily

The actual distribution and structure of cork oak woods is the result of a process of anthropogenic alteration (utilization of cork, deforestation, coppicing, overgrazing, changes in land use, fire). Additional causes of threats in Q suber woods are pests and fungal disease. Although cork oak is an active pyrophyte the decortication of trunks makes trees more vulnerable to external agents and to fire in particular. Post-fire species are mainly carbonicolous fungi, some Ascomycetes make their appearance after around six weeks while other fungi begin to appear from the second year. The proliferation of fungal hyphae in the ash, as well as of some pioneer mosse protonemata, promotes soil aggre…

Chemical composition and antimicrobial activity of the essential oils of some species of Anthemis sect. Anthemis (Asteraceae) from Sicily

The chemical composition of the essential oils isolated from the aerial parts of Anthemis arvensis L. subsp. arvensis, Anthemis cretica subsp. messanensis (Brullo) Giardina & Raimondo and from flowers and leaves of Anthemis cretica subsp. columnae (Ten.) Frezén were determinated by GC–FID and GC–MS analyses. Torreyol (85.4%) was recognised as the main constituent of the Anthemis arvensis subsp. arvensis essential oil, while in the essential oils of Anthemis cretica subsp. messanensis, collected on the rock and cultivated in Hortus Botanicus Panormitanus, (E)-chrysanthenyl acetate (28.8 and 24.2% resp.), 14-hydroxy-α-humulene (8.1 and 5.3% resp.), santolina triene (8 and 5.8% resp.) and …

Hydrophytic vegetation aspects in the Nebrodi mountains (Sicily)

The vegetation of damp areas in the Nebrodi Natural Park was already surveyed in some studies (Brullo et al. 1994). In particular, the various hygro and hydrophytic aspects were referred to associations belonging to the Phragmitetea and the Potamogetonetea classes respectively. Small lacustrine habitats in Sicily have disappeared almost everywhere and are conserved still today only in the Nebrodi Mountains. They host widely distributed hydrophytes. Some of these plants are rather localized in Sicily, e.g. Potamogeton polygonifolius Pourr. and Utricularia australis R. Br. The latter occurs also in the Madonie Mountains. Recent analyses revealed some hollows characterized by an accentuated re…

The landscape of the manna ashes in Sicily

The manna ashes are related to wild species of the genus Fraxinus, namely F. ornus (true manna ash) and F. angustifolia (narrow leaved ash). About two centuries ago, several varieties of such species, selected in ancient times, were widely cultivated for extracting the manna drug. This represented a remarkable economic resource for the region. Manna was extracted mainly for pharmacological industry, but today it has became a herbal product. Irrespective of the processes that reduced this cultivation to the lowest extent, the manna ash landscape is a remarkable peculiarity in the frame of the Mediterranean agrosystems. It is still kept alive as a relict cultivation within a very restricted a…

Hieracium nebrodense Tineo ex Lojac., a little-known endemic of Sicily, has been rediscovered from the type locality after almost two centuries since its first and only collection made in 1830 in the Madonie Mountains (N Sicily). In line with the treatment in ‘Med-Checklist 2’, it is reclassified as a subspecies of H. schmidtii. A new combination is made and a detailed description and illustration are provided.

Chemical composition of the essential oil of Centaurea sicana and C. giardinae growing wild in Sicily

The essential oils of Centaurea sicana (S) and C. giardinae (G) were studied by GC and GC-MS. Thirty constituents for S, representing 81.5% of the total oil, and 24 compounds for G (94.2% of the total) were identified. The oils were rich in sesquiterpenoids (47.9% for S and 54.7% for G) and hydrocarbons (25.9% for S and 31.7% for G). Germacrene D (13.3%), (E)-β-farnesene (8.3%), nonacosane (7.3%), heptacosane (6.5%) and phytol (6%) were recognized as the main constituents for S, while caryophyllene oxide (17.7%), nonacosane (14.5%), germacrene D (11.5%), caryophyllene (11.2%) and heptacosane (10.3%) were the main compounds for G.

Measurement and Conservation of Species and Habitat Biodiversity at Different Scales on Small Mediterranean Islands

In this paper we discuss current methodologies for measuring biodiversity, analyse pros and cons at different scales, and finally propose distribution mapping as the most suitable method for measuring floristic biodiversity on small Mediterranean islands. These territories often host endangered flora and habitats, and have peculiarities that distinguish them from the mainland and the larger islands.

Typification of names of taxa Compositae described from Sicily by Michele Lojacono Pojero

Lojacono described and named 89 new Compositae taxa (32 species, 52 varieties, 5 formae), mostly in his Flora sicula, in 1903, but sometimes in earlier, lesser known papers. In spite of problems (here discussed) to find and recognise his original material in the Palermo Herbarium (PAL), for 58 names types (mostly here designated) have been found in Palermo. Discounting 3 names typified by illustrations and 5 with lectotypes designated in Naples and Geneva, 23 remain that cannot be typified for the time being. Eleven of Lojacono’s new species names are still in use currently. Among them is Filago cuneata, long forgotten but here redeemed.

Typification of eight names in Hieracium (Asteraceae)

Eight names in Hieracium (H. atrovirens Froel., H. crinitum Sm., H. lucidum Guss., H. pallidum Biv., H. racemosum subsp. todaroanum Zahn, H. siculum Guss., H. siculum var. minus Guss., H. symphytifolium Froel.), the descriptions of which are based totally or in part on Sicilian material, are typified. Hieracium racemosum subsp. todaroanum is treated as a synonym of H. crinitum, and H. siculum and H. siculum var. minus are treated as synonyms of H. symphytifolium. Hieracium atrovirens is recognized as a subspecies of H. murorum L. (H. murorum subsp. atrovirens (Froel.) Raimondo & Di Grist.).

Preserving Biodiversity in Marginal Rural Areas:Assessment of Morphological and Genetic Variabilityof a Sicilian Common Bean Germplasm Collection

The historical cultivation of common bean (Phaseolus vulgaris L.) has resulted in the development of local populations/cultivars in restricted Italian rural areas. Many common bean landraces, still cultivated in small mountain areas from Sicily, have become outdated and endangered due to the commercial varieties spreading. These accessions are poorly known but often represent a genetic heritage to be preserved and enhanced. The ex situ conservation of fifty-seven Sicilian common bean landraces was carried out at the &ldquo

Acquisizioni filogenetiche e variazioni tassonomiche in alcune rosacee legnose della flora Italiana

In Italia, secondo la recentissima sintesi di Bartolucci et al., la flora vascolare nativa sarebbe rappresentata da 1092 generi di piante vascolari. Fra di essi ricorre Sorbus L. (Rosaceae) a cui vengono attribuiti 11 taxa specifici e sottospecifici (ivi compresi alcuni taxa ibridogeni) e un dodicesimo taxon da confermare nel territorio italiano. In questo contributo si vuole porre attenzione proprio alla recentissima checklist europea di Sorbus s.l. basata su acquisizioni di carattere filogenetico sul gruppo e, più in generale, sulle Pyrinae. In particolare, si fa riferimento allo studio di Sennikov, Kurtto in cui Sorbus L. viene praticamente smembrato in numerosi altri generi, mentre i ta…

Types of names of taxa belonging to theCentaurea cinerariagroup (Compositae) described from Sicily

The group of Centaurea (sect. Acrolophus) cineraria (Compositae) in Sicily includes four currently accepted species plus four taxa that have been considered, with some doubt, as subspecies of one of them (C. panormitana). In total, discounting recombinations and replacement names, 11 names (seven specific, three varietal, one of a forma), all based on Sicilian material, were published by past authors for these eight taxa. Two of the names had their holotype indicated upon publication; two have been lectotypified previously; six (C. busambarensis var. obtusiloba, C. cineraria var. soluntina, C. cineraria var. umbrosa, C. todaroi, C. todaroi f. seguenzae and C. ucriae) are lectotypified here;…

Essential Oil Composition and Antibacterial Activity of Anthemis mixta and A. Tomentosa(Asteraceae)

In the present study the chemical composition of the essential oils from aerial parts and roots of Anthemis mixta L. and A. tomentosa L. was evaluated by GC and GC-MS, and their antibacterial activity tested against ten bacterial species. Hexadecanoic acid (15.2%) was recognized as the main constituent of A. mixta, together with τ-cadinol (6.7%), while in both aerial parts and roots of A. tomentosa nonacosane (21.9% and 20.7%), heptacosane (8.1% and 6.0%), hexadecanoic acid (8.1% and 27.1%) and hexahydrofarnesylacetone (6.8% and 5.5%) prevailed. The oils from aerial parts of both species showed a good activity against Gram-positive bacteria. These results suggest that the plants could be p…

Essential oil of Citrus lumia Risso: Phytochemical profile, antioxidant properties and activity on the central nervous system

Citrus lumia Risso Essential oil Antioxidant properties Anti-cholinesterase activity Cytotoxicity Neuroactive effects 1. Introduction Plants that produce essential oils (EOs) represent a large part of natural flora and an important resource in various fields such as pharmaceutical, food and cosmetic industries, due to their flavor, fra- grance and biological activity (Swamy et al., 2016). EOs play a pivotal role in the growth and colonization of plants, giving color and scent to reproductive organs, attracting pollinators, favoring seed dispersion (Sharifi-Rad et al., 2017), and defending the plant against abiotic (light, temperature, etc.) and biotics (herbivores, harmful insects and pa- t…

Genetic relationships between Sicilian wild populations of Brassica analysed with RAPD markers

Brassica comprises very variable species, both morphologically and genetically. Among these species, the Sicilian populations of Brassica sect. Brassica, species related to kale crops form a complex group. The genetic relationships among 15 populations occurring in Sicily and one from Calabria, representing the existing diversity, have been investigated using random amplified polymorphic DNA (RAPD) markers. This assay, carried out with 22 arbitrary primers, generated 236 polymorphic fragments, 21 of which were specific for single populations (mainly Brassica insularis, Brassica incana and Brassica macro-carpa). Jaccard's genetic distances were computed and the phylogenic tree was establishe…

Isozyme analysis of genetic diversity in wild Sicilian populations of Brassica sect. Brassica in view of genetic resources management

In Sicily and in the small surrounding islands the section Brassica of the genus Brassica comprises five species, B. insularis Moris, B. incana Ten., B. macrocarpa Guss., B. rupestris Raf. and B. villosa Biv. These taxa represent a genetic resource as relatives of kale crops but some populations are endangered or threatened, thus isozyme analyses were performed to assess the genetic diversity degree at population and species levels in order to assist the design of conservation management programs. Eleven loci from five enzyme systems (aconitase, leucine aminopeptidase, 6-phosphogluconate dehydrogenase, phosphoglucoisomerase phosphoglucomutase) were analyzed in sixteen natural population (fi…

Peat florulas in the Madonie Regional Park (Sicily)

The floristic exploration of the eastern slopes of the Madonie Mountains in Sicily, carried out between 1975 and 1980, resulted in the discovery of several hydromorphic environments characterized by a thick peaty horizon. Locally named “margiu” or “triemula”, depending on the lower or higher depth, they host plant communities characterized by some species of Juncus and Carex together with acidophilous bryophytes including some species of Sphagnum. Their ecology as well as their flora and vegetation have been studied (Petronici et al. 1978). In some localities fossil pollens have also been examined (Bertolani Marchetti et al. 1984). Floristic analyses pointed out some phytogeographical patte…

Alnus glutinosa (L.) Gaertn. and Alnus cordata (Loisel) Duby as new sources of safe cosmetic and pharmacological anti-melanogenic agents

The genus Alnus (Betulaceae) comprises many species with a long history in traditional medicines. The crude extracts and isolated compounds from Alnus species exhibit a wide spectrum of in vitro and in vivo pharmacological activities (1). Phytochemical investigations revealed the presence of diarylheptanoids, a class of natural products typically found in Alnus genus with two aryl groups joined by a heptane chain in the main skeleton that have drawn attention due to their multiple biological properties and their therapeutic potential (2). A previous study reported that oregonin and other structurally analogous diarylheptanoids isolated from the bark of A. hirsuta showed inhibitory effects o…

Hybridization and competition between the endangered sea marigold (Calendula maritima, Asteraceae) and a more common congener

Occurrences of hybridization between the rare, endangered Sicilian endemic, Calendula maritima, and other congeners in the wild have been suspected by several authors, but never demonstrated. In San Cusumano (Trapani), one of the only three Sicilian mainland populations, C. maritima occurs in close proximity to the more common congener C. suffruticosa subsp. fulgida, and individuals morphologically intermediate between the two taxa have been observed. In order to determine whether hybridization is occurring at this site, and, if so, begin to assess the impact it could have on C. maritima, two independent tests of hybridity were conducted by studying (1) the pollen morphology and viability a…

Spatial Representation of Plant Diversity at Geographical Scale: The Italian Experience

The first attempts to draw up plant biodiversity maps in Italy are identified, some of which represent re-workings of data collected for chorological atlases of geographic areas of different extents. These were based particularly on the UTM grid, introduced and codified in Italy by Pignatti [6]. The limited examples made in Italy concern regional, provincial or district areas, some also in protected natural areas. As examples considered original, the maps developed at the Phytotaxonomy and Phytogeography Laboratory of the University of Palermo are presented. These involve the province of Palermo, the Madonie Natural Park in Palermo province, and the eastern Sicani mountains. The map of this…

Morpho-anatomical analysis of Viola tineorum and V. ucriana (Violaceae) endemic to the mountains around Palermo (NW-Sicily

Viola sect. Melanium is represented in Sicily by six species. Two of them, originally described as varieties of Viola nebrodensis, were later transferred at the species rank and named V. tineo- rum and V. ucriana. The study of micromorphological characteristics gives additional evidence agreeing with the independent specific status of V. tineourum and V. ucriana, that are confined to two very restricted areas south of Palermo: Rocca Busambra and Monte Pizzuta respectively.

The Isoetes longissima complex (Isoetaceae) in Italy: observations on the morphology of spores and leaves, and taxonomic implications

The morphological variability of the Isoetes longissima complex in Italy has been analyzed, on the basis of selected herbarium specimens. Observations were made on spore ornamentation and size, number of leaves per plant and maximum leaf length, velum extension and alae width in the basal portion of leaves. The first count of chromosome number on plants from Italy is also made. On the basis of our observations, the five taxa here considered are attributed to two taxa, treated at the species level as follows: I. longissima (incl. I. velata and I. velata [unranked] sicula), and I. tiguliana (incl. I. dubia). Italian distribution of these species is also given.

Natura e architettura nel giardino di Villa Florio-Pignatelli (Palermo, Sicilia).

ABSTRACT.– Amongst the Sicilian historical gardens it is merited to remember the ornamental garden design of Villa Florio- Pignatelli, situated in the western periphery of Palermo. The building, and probably the garden too, are from the second half of the 18. century. This article contains the result of a cognitive study of its history, architecture and vegetal composition, based on field studies in the garden itself, on bibliographical and archival work. In 1838 it was sold by the Duke of Cumia to Vincenzo Florio, who in following conceded it to his son Ignazio. Already at this time, there was a garden with a "flora all’Italiana" behind the Villa, which had circular vials in radial order, …

Spatial representation of vegetation and floristic diversity at landscape scale: the Italian experience

The application of phytosociology to the analysis of vegetation and landscape diversity has greatly developed in Italy during the past 60 years. The analysis of the scientific production of this period is therefore fundamental for a reflection on vegetation mapping and may be useful to forecast future scenarios of this discipline (Bruno et al., 2003). Many different documents related to the plant species distribution and diversity became available over time from different land units of Italy. In particular, interesting examples of mixed floristic and vegetation maps have been produced in a pilot project for the province of Palermo (Sicily) and used in the diagnosis of environmental heteroge…

Agricultural landscapes and biodiversity conservation: a case study in Sicily (Italy)

The diversity of life is made up not only of the diversity of plants and animal species, habitats and ecosystems, but also of the diversity of human cultures. These diversities interact with one another in complex ways and express the mutual adaptation between humans and the environment at local level. Sicilian traditional agro-ecosystems, due to the history of the territory and the resulting social and economic context, are configured in a heterogeneous mosaic rich in residual features of environmental value, which enhance the connectivity of the ecological network and support a high proportion of species that are rare or of conservation concern. As a case study we analyzed the characteris…

Pyrus vallis-demonis (Rosaceae), a new species from the Nebrodi Mountains (NE-Sicily).

The genus Pyrus in Sicily is represented by P. amygdaliformis Vill., P. communis L., P. pyraster Burgsd. and, in addition, by several other taxa such as P. pyrainus Raf., P. cuneifolia Guss., P. parviflora Desf., P. sicula Tin., P. tinei Tod. ex Decne, etc.. These taxa, presently considered at lower rank or quite insignificant from the taxonomical point of view, show on the whole a remarkable morphological diversity. Therefore, new field surveys and collections in the whole Sicilian area as well as the revision of the herbarium material were started up some years ago. As a first result of these surveys, a new species occurring in the Nebrodi Regional Park (NE Sicily) has been found and is h…

The new sites fall in Madonie Mts., where the species is found at the edge of Quercus petraea (Matt.) Liebl. and Fagus sylvatica woods, growing on quartzarenitic substratum at 1200-1800 m of elevation. These new localities are placed at the south-western limit of Fagus sylvatica distribution area, on both north-facing [Contrada Sempria (Castelbuono) and slopes of Madonna dell’Alto (Castellana Sicula)], and south-facing slopes [Locality Prato (Polizzi Generosa)].

Taxonomic remarks and distribution of Smyrnium dimartinoi (Apiaceae)

Smyrnium L., an Eurasian genus of the family Apiaceae, includes about 20 taxa of which only 7 are accepted at specific rank; among these, 5 are native to Europe (Tutin & al. 1968; Gomez 2003). In the Italian flora, the genus is represented by 3 taxa also occurring in Sicily (Pignatti 1982; Giardina & al. 2007); these are Smyrnium olusatrum L., S. perfoliatum L. and S. rotundifolium Mill. The last one has also been treated at the rank of subspecies under S. perfoliatum [S. perfoliatum subsp. rotundifolium (Mill.) Hartvig] (Strid 1986; Conti & al. 2005), or as a variety [S. perfoliatum var. rotundifolium (Mill.)Fiori (Fiori 1925)]. In Sicily, same populations related to S. perfoli…

MONOTROPA HYPOPHEGEA WALLR., A NEW RECORD FOR THE SICILIAN FLORA

During field investigations in the Mountains around Palermo, an unusual population of Monotropa sp. was found. After revision of the taxonomic literature and herbarium specimens, it was referred to Monotropa hypophegea Wallr. This species is closely related to M. hypopytis L., and in the past was considered only a variety (Pignatti 1982) or a subspecies (Křisa 1972) ) of it. More recently this entity has been considered an independent taxon deserving the rank of species (Conti et al. 2005). The most important morphological differences between the two taxa are the number of flowers in the raceme and the hairiness of sepals, petals and capsule. The individuals of the observed population have …
