Note distributive ed ecologiche su alcune rare entità della flora vascolare siciliana

subject

description

Distributive and ecological notes on some rare species of the Sicilian vascular flora. In this paper we point out some new populations of some vascular species found during floristic investigations carried out mostly in the inland of Sicily. For each taxon we provide also data regarding ecological characterization and geographical distribution in the island. Among this taxa, three are Sicilian endemics [Brassica villosa Biv. subsp. tinei (Lojac.) Raimondo et Mazzola, Erysimum metlesicsii Polatschek and Euphorbia papillaris (Boiss.) Raffaelli et Ricceri], four species of biogeographical importance [Allium cupanii Raf., Chaenorhinum rupestre (Guss.) Speta, Sedum gypsicola Boiss. et Reuter and Stipa barbata Desf.] and a xenophyte [Setaria parviflora (Poir.) Kerguélen], up to now known for few urban areas of Sicily.
