Stazioni nuove di Euphorbia hypericifolia (Euphorbiaceae) e di Phyllanthus tenellus (Phyllanthaceae) in Sicilia
2017
New localities for Euphorbia hypericifolia (Euphorbiaceae) and Phyllanthus tenellus (Phyllanthaceae) in Sicily – Two new adventive plants, Euphorbia hypericifolia (Euphorbiaceae) and Phyllanthus tenellus (Phyllanthaceae), are reported in the Palermo’s urban area. These two taxa belonging to closely related families were both already known from the province of Messina (E. Sicily), the first one near the Messina town, the second near Taormina. The new localities expand toward west the Sicilian distribution of the two taxa, so that these appear to likely occur in other urban contexts of the island. Finally, as far as the accession road to the island is concerned, the- se two aliens – that have…
Typification of the Presl’s name Calamintha canescens (Lamiaceae)
2021
Calamintha canescens is a taxon described in the “Flora Sicula” by K. B. Presl (1826), following the visit made to Sicily a few years earlier (March-July 1817). In the protologue Presl does not report any data on the distribution in Sicily of this taxon that will be almost completely forgotten in later floristic works. Only Nyman (1881) and later Šilić (1979) consider it as a variety respectively of Calamintha nepeta (L.) Savi and C. glandulosa (Req.) Benth. Following the review of a group of critical European taxa belonging to the genus Clinopodium L., lately Melnikov (2016) recovers the ancient taxon Calamintha canescens C. Presl and transfers it to the genus Clinopodium L. Also, the auth…
Clinopodium raimondoi (Lamiaceae), a new species from Sicily
2015
On the basis of the taxonomic study of the collections made by F. M. Raimondo, kept in PAL, a new species of Clinopodium is described. The new taxon, named Clinopodium raimondoi, occurs in N-W coast of Sicily on limestone substrata, in steppe communities dominated by Hyparrhenia hirta. The main distinctive characteristics of C. raimondoi, with respect to other taxa known from Europe and other Mediterranean countries, are the large size, the opposite and decussate branches, and the clearly woody at base stems of mature plants as well. Relationships of the new taxon with the Mediterranean ones in the C. nepeta group are also discussed.

2015
Hieracium hypochoeroides subsp. peracutisquamum, a new taxon endemic to Basilicata (southern Italy), is described and illustrated. It is confined to the carbonate rocks of Monte della Madonna di Viggiano (Lucanian Apennine, SW Basilicata). Information on its ecology and taxonomic relationships is provided.
