<p><strong>Lectotypification of six names of species of <em>Scabiosa</em> s.l. (Caprifoliaceae) endemic to North Africa and r…
2020
As part of an ongoing project for the investigation of the Algerian-Tunisian flora, six names of species of Caprifoliaceae subfam. Dipsacaceae, endemic to central and western North Africa, described in the 19th and 20th Centuries under the genus Scabiosa, are here lectotypified. They are: Scabiosa camelorum Cosson & Durieu, Scabiosa cartenniana Pons & Quézel, Scabiosa daucoides Desf., Scabiosa farinosa Cosson, Scabiosa parielii Maire, and Scabiosa robertii Barratte. Taxonomic notes, distributisson and new unpublished data about plant phenology of these taxa are given.
Phytochemical study of Cistus libanotis L.
2015
n continuation of our ongoing study on Mediterranean Flora, we focused the attention on Cistus genus. These plants possess interesting secondary metabolites and are used in many fields, principally in perfumery and more recently as raw material for food supplements (botanicals). n this article, we report the phytochemical analysis of Cistus libanotis L. from Tunisia. Among the diterpenes, labdane compounds resulted absent, in favour of two clerodanes, one of that never reported in Cistus sp. The main representative compounds were found to be several flavonoids with various grades of O-methylation. Other interesting components were two cinnamic esters of borneol, reported here for the first …
Analysis of the bryophyte diversity of mountain ranges in Sicily.
2015
The focus of this study was an analysis of the bryophyte flora of the main Sicilian mountain ranges, i.e., Peloritani, Nebrodi and Madonie mountains, located along the northern side of the Island, the Sicani mountains, located in the west-central Sicily and the Etna, the highest and most active volcano of Europe. The overall bryoflora consists of 504 taxa, 400 mosses and 104 liverworts and hornworts. It represent the 85.3% of the whole Sicilian flora; the mosses are referred to 37 families, the liverworts together with hornworts to 31 families. The phytogeographical analysis has shown the prevalence of the Mediterranean species, with the highest value on the Sicani mountains. It is notewort…
Chemical Constituents and Biological Properties of Genus Doronicum (Asteraceae)
2021
The genus Doronicum, belonging to tribe Senecioneae (Fam. Asteraceae), is found mainly in the Asia, Europe and North Africa. This genus of plant has always been used in traditional medicinal treatments due to the many biological properties shown such as killing parasitic worms and for relieving constipation, as well as to improve heart health, to alleviate pain and inflammation, to treat insect bites, etc. According to the World Flora the genus Doronicum contains 39 subordinate taxa.[1-3] The purpose of this article, which covers data published from 1970 to 2021 with more than 110 articles, aims to carry out a complete and critical review of the Doronicum genus, examining traditional uses a…
Crassula campestris(Eckl. & Zeyh.) Endl.(Crassulaceae), a new record for the Italian flora
1998
Abstract Brullo, S., Campo, G., Marceno, C., Romano, S. & Siracusa, G.: Crassula campestris (Eckl. & Zeyh.) Endl. (Crassulaceae), a new record for the Italian flora. — Willdenowia 28: 53–58. 1998. — ISSN 0511-9618. Crassula campestris, a species widespread in S Africa, was discovered in Sicily near Palermo, which is a new record for the Italian flora. A description and illustration of C. campestris is provided and the species is compared with C. tillaea and C. basaltica, the two other Crassula species in Sicily.
A survey of the epiphytic bryophyte flora of the Rif and Tazzeka Mountains (northern Morocco)
2005
SUMMARY The catalogue of the epiphytic bryophyte flora of the Rif Mountains includes a total of 72 taxa, of which 66 are mosses and six are liverworts. Some new records are provided: Hypnum resupinatum and Tortula israelis, new to northern Africa, Antitrichia curtipendula and Cryphaea heteromalla, new to Morocco, and Dicranoweisia cirrata, Isothecium alopecuroides and Orthotrichum macrocephalum ,n ew to the Rif Mountains. Epiphytic communities in the different forest types have been analysed, with the conclusion that altitude and humidity are the main factors that determine their composition. The epiphytic stratum is best developed at the highest altitudes on the Principal chain and Tazzeka…
Solanum lanceolatum (Solanaceae) in Sicily: A new alien species for the European flora
2015
Solanum lanceolatum Cav. (Solanaceae) is a species native to Central America (Mexico, Belize, Guatemala and Panama), that has been found naturalized near Sutera and Porto Empedocle (Sicily). This is the first record in Italy and Europe.
Plagiochasma appendiculatumLehm. & Lindenb. (Marchantiales, Aytoniaceae), a species new to the European bryophyte flora
2005
Abstract The liverwort Plagiochasma appendiculatum Lehm. & Lindenb. is reported for the first time in Europe from Mallorca (Balearic Islands, Spain). The species is described and illustrated and its distribution and ecology are discussed. Plagiochasma appendiculatum differsfromP. rupestre (J. R. Forst. & G. Forst.) Steph., the only species of the genus known at present in Europe, by characters such as the bright green or green-yellowish thallus and the orbicular and obtusescale appendages which are markedly constricted and folded at the base.
Additional reports for Italian moss flora.
2013
As a result of the study of both recent collections and a review of herbarium specimens, the following taxa are reported for the first time from various Italian regions: Hedwigia stellata Hedenas, Hedwigia ciliata var. leucophaea Bruch & Schimp., Pleurozium schreberi (Willd. ex Brid.) Mitt. and Ptychostomum compactum Hornsch. var. compactum. The last taxon is new for southern Italy, while the report of Pleurozium schreberi confirms the occurrence of this species in southern Italy after more than half a century. Moreover, Crossidium laxefilamentosum Frey & Kurschner represents the second report of this species from Italy.
First record of Ribes uva-crispa L. (Grossulariaceae) from the Madonie Mts., a new species of the Sicilian flora.
2011
Abstract In this study, a first record of Ribes uva-crispa L. (Grossulariaceae) – a new species of the Sicilian flora – from the Madonie Mts. is reported. The autochthonous and relict new population of Ribes uva-crispa L. (Grossulariaceae) is found on Mount Carbonara (Madonie Mts., North-Central Sicily), which is several hundred kilometers away from the Central Apenninic and the South Mediterranean locations of its distribution range. R. uva-crispa shows a distribution similar to other taxa extending from the Euro-Asiatic area to the mountains of North Africa with disjunct populations on the main Sicilian reliefs (Madonie and Nebrodi Mts.), testifying ancient phytogeographical connections. …
