Notulae to the Italian native vascular flora: 7
2019
In this contribution, new data concerning the distribution of native vascular flora in Italy are presented. It includes new records, confirmations and status changes to the Italian administrative regions for taxa in the generaAcer,Alchemilla,Andrachne,Bromus,Clinopodium,Colchicum,Damasonium,Erodium,Festuca,Hieracium,Hyparrhenia,Ipomoea,Linaria,Lolium,Narcissus,Ranunculus,Sisymbrium,Stipa,Valerianella,Vicia, andZannichellia. New combinations in the genusZiziphora(Z.sardoaandZ.corsica) and the new subspeciesUlmusminorsusbp.canescensare proposed. Furthermore, the name Calaminthaalpinavar.sardoa is here lectotypified. Nomenclatural and distribution updates, published elsewhere, and corrigenda a…
Nomenclatural synopsis of cirsium sect. Eriolepis (asteraceae) in Italy
2021
The names of the Italian taxa in Cirsium sect. Eriolepis are discussed. The accepted names are: Cirsium echinatum, C. eriophorum subsp. eriophorum, C. eriophorum subsp. spathulatum, C. ferox, C. italicum, C. lacaitae, C. lobelii, C. morisianum, C. scabrum, C. tenoreanum, C. vallis-demonii subsp. vallis-demonii, C. vallis-demonii subsp. calabrum comb. nov., and C. vulgare (= C. crinitum, C. sylvaticum). Four accepted names are typified by specimens preserved at FI (one lectotype), G (one lectotype and one neotype), P (one lectotype), and by illustrations (two lectotypes). Several other heterotypic synonyms of taxa described from Italy are discussed and six of them are typified. A new combina…
First record for the flora of Italy and lectotypification of the name Linum elegans (Linaceae)
2017
Linum elegans has been detected in calcareous rocky garrigues on the Gargano promontory (Apulia, SE-Italy), representing the first record for the Italian flora and the first one outside the Balkan Peninsula. The geographical disjunction may provide evidence for past amphi-Adriatic/amphi-Ionic terrestrial connections. The population found was ascribed to L. campanulatum in the past. As a consequence, a comparison between these two species is undertaken. Furthermore, the name L. elegans is here lectotypified on a specimen preserved at G, and the IUCN assessment of the species in Italy is briefly discussed.
Multivariate morphometric analysis of the Stipa turkestanica group (Poaceae: Stipa sect. Stipa)
2015
Based on numerical analyses of macromorphological characters (cluster analysis, principal coordinate analysis and principal component analysis), scanning electron microscopy observation of lemma and lamina micromorphology, as well as field observations, five taxa belonging to the Stipa turkestanica group have been recognized in the mountain area of Central Asia. They are S. turkestanica subsp. turkestanica, S. turkestanica subsp. trichoides, S. macroglossa subsp. macroglossa, S. macroglossa subsp. kazachstanica and S. kirghisorum. As a result of this study, we propose one new combination, S. macroglossa var. pubescens, and designate lectotypes for S. turkestanica subsp. trichoides and S. ma…
The Libyan Collections in FI (Herbarium Centrale Italicum and Webb Herbarium) and Studies on the Libyan Flora by R. Pampanini – Part 2
2016
This work is the continuation of Part 1, published in 2015, and comprises the reconstruction of the original collections of new taxa described by R. Pampanini and other botanists and, where possible, typification of the new names and taxonomical updating. The material studied for the most part concerns Libyan specimens held in the FI and FI-W herbaria but in some case also K, LD, MPU, P, PAD, PAL, ULT. Other material, which Pampanini studied in Florence was subsequently conserved in other herbaria. Specimens belonging to 21 families have been examined, from the Najadaceae to Zygophyllaceae. As well as typification, bibliographical data have been provided for those already typified. In this …
Morphological, karyological and taxonomic remarks on Ferulago nodosa (L.) Boiss. (Apiaceae)
2012
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…
Lectotypification of Arnica montana L. (Asteraceae)
2021
A lectotype for Arnica montana L. (Asteraceae) is designated from Linnaeus’ original material preserved in the UPS-BURSER herbarium.
The genusThymus(Lamiaceae) in Sicily
2015
An update on the taxonomy and geographic distribution of the genus Thymus in Sicily is given. This study is based on literature, herbarium and field investigations. In total, five taxa belonging to Thymus sect. Serpyllum (Th. richardii subsp. nitidus, Th. longicaulis and Th. praecox subsp. parvulus) and Th. sect. Hyphodromi (Th. spinulosus and Th. paronychioides) occur in Sicily. For each one, information about taxonomy, habitat, phenology, chromosome number and distribution are provided. Furthermore, the name Thymus pedicillatus Lojac. is here typified. Finally, an analytical key for the identification of the studied taxa is proposed.
A critical conspectus of ItalianIsoetes(Isoetaceae)
2014
The work on the Isoetaceae account for the Critical Flora of Italy has resulted in a new, synonymic inventory of Italian Isoetes taxa, based on herbarium studies, observation by scanning electron microscopy and critical re-examination of the previously published works. Ten species are listed. The names I. longissima and I. gymnocarpa are restored as correct, to replace I. velata and I. subinermis, respectively. Eighteen lectotypes, one epitype and one neotype are designated. A dichotomous key to Italian taxa is provided.
Typification of the name Lavatera agrigentina (Malvaceae)
2019
As part of an ongoing study on the names of vascular plants described from Sicily (Southern Italy), a nomenclature investigation on the name Lavatera agrigentina Tineo, basionym of Malva agrigentina (Tineo) Soldano, Banfi & Galasso in Banfi et al., which appears to be yet untypified, is here presented.
