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.
New records of Asteraceae for the non-native flora of Tunisia and north Africa with some nomenclatural remarks
2022
International audience; Sixteen new Asteraceae are added to the non-indigenous flora of Tunisia. Six of them (Dimorphotheca ecklonis, Gaillardia pulchella, Gazania linearis var. linearis, Guizotia abyssinica, Rudbeckia triloba and Tithonia diversifolia) are also new for the flora of North Africa. Chrysanthemum morifolium is here first reported for the Mediterranean Basin. Seven genera (Argyranthemum, Bidens, Dimorphotheca, Gaillardia, Guizotia, Rudbeckia and Tithonia) are recorded for the first time for the vascular flora of Tunisia. Most of these species escaped from gardens and pots and became casual along roadsides and/or disturbed areas after cypsela dispersion (except for Chrysanthemum…
Typification of the name Statice calcarae (Plumbaginaceae), basionym of the threatened endemic Limonium calcarae
2018
Limonium calcarae (basionym Statice calcarae), a rare diploid species endemic to Sicily, is one of the few members of the genus that occurs in the inland areas of the island. According to IUCN criteria, it has been assessed as critically endangered but recent data on its distribution, demography and threats affecting its populations are lacking. A lectotype is designated, preserved at PAL, and isolectotypes have been traced and verified in other European herbaria.
<strong>Nomenclatural types of <em>Hieracium</em> (Asteraceae) species described from the Balearic Islands (Spain) and several rela…
2021
A nomenclatural revision of the genus Hieracium in the Balearic Islands (Spain) is presented and the typification of five names: H. aragonense Scheele, H. balearicum Arvet‑Touvet, H. elisaeanum Arvet-Touvet ex Willkomm, H. majoricanum Arvet-Touvet and H. microscapum Arvet-Touvet, is discussed. The names are lectotypified using specimens preserved at COI, GRM, and P herbaria. Several comments for the names H. cataractarum Arvet-Touvet & Huter and H. praecox subsp. brachypus Freyn in Porta & Rigo are also provided.
Typification of Dactylis ibizensis (Poaceae) and inference of the ploidy level of the type specimen

Typification of names inDrabasect.Aizopsis(Cruciferae, Arabideae) based on material from Italy
2013
Names of 20 presumed taxa in Draba sect. Aizopsis, all based on material from Italy, are considered. Full synonymies are provided, and types are designated (for 14 names) or indicated. Most of the taxa are currently considered unworthy of recognition, of which 16 belong to D. aspera sensu lato. However, the question of whether the Sicilian populations might be distinct from the peninsular populations is still unsettled.
REVISION OF THE MEDITERRANEAN AND SOUTHERN AFRICAN TRIGLOCHIN BULBOSA COMPLEX (JUNCAGINACEAE)
2010
The Triglochin bulbosa complex (Juncaginaceae) from the Mediterranean region and Africa is revised. One new species, Triglochin buchenaui Köcke, Mering & Kadereit, and two new subspecies, Triglochin bulbosa subsp. calcicola Mering, Köcke & Kadereit and Triglochin bulbosa subsp. quarcicola Mering, Köcke & Kadereit, are described from South Africa. The only two Mediterranean taxa in the complex (Triglochin barrelieri, T. laxiflora) are elevated to species rank. Altogether seven species and four subspecies are recognised: Triglochin barrelieri, T. buchenaui, T. bulbosa subsp. bulbosa, T. bulbosa subsp. calcicola, T. bulbosa subsp. quarcicola, T. bulbosa subsp. tenuifolia, T. compac…
Remarks on the type material of Linaria cavanillesii Chav. (Antirrhineae, Veronicaceae)
2013
ABSTRACT Some aspects concerning the type material of Linaria cavanillesii Chav. (Antirrhineae, Veronicaceae), which are conserved in different herbaria, are discussed. This name had previously been lectotypified on Tournefort's collections that are kept at the herbarium P, though they had been regarded erroneously as syntypes. Evidence is shown on the existence of a duplicate of the lectotype (isolectotype), which is conserved among the Salvador herbarium at BC (Institut Botanic de Barcelona), as well as of syntypes deposited in MA on which the illustration by Cavanilles cited in the protologue was drawn. Historical data are reported on collection sites and dates for all cited syntypes of …
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.
