Towards a Critical Flora of Italy: Assessing the Lycopodiophyta

Taxonomy and conservation in Higher Plants and Bryophytes in the Mediterranean Area

The Mediterranean Region is among the areas of the world richest in wild and cultivated taxa. Extinctions in the Mediterranean area are bound to have occurred in historical times but they are not documented. The probable and documented cases of plant extinction in specific areas within the Mediterranean are equivalent to 0.25% of total species-by-area records. Species with a large range are more prone to local population size fluctuations and eventual extinction than species with a reduced population. Small islands floras are more prone to extinction than those on large islands and on the mainland. Reliability of our data on Mediterranean plant extinctions is poor. New emphasis on floristic…

Conspectus of Italian Selaginella (Selaginellaceae), with some typifications

An annotated synonymic inventory of Italian Selaginella taxa, a practical key for their identification and their dot distribution maps are presented, as a result of our work on the Selaginellaceae account for the Flora Critica d'Italia. The names Lycopodium helveticum L. and Selaginella denticulata var. platystachya Hieron. are typified.

A note on the type of Orobanche sanguinea C. Presl (Orobanchaceae), nom. cons. prop

The type specimen of Orobanche sanguinea C. Presl, still identifiable even though damaged, belongs to the species generally known under that name. It is therefore unnecessary to conserve Presl's name with a conserved type, as has been proposed. To eliminate any future controversy over the application of the name Orobanche sanguinea, an epitype is designated.

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…

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…
