Indagine biosistematica su Scilla sensu lato in Italia e generi affini

The taxonomic assessment of the genus Scilla s.l. and its related genera growing in Italy is defined based on literature data and our own morphological, karyological and phenological studies. A cladistic analysis is also performed in order to test taxonomic role of the selected diagnostic characters. Results agree with the most recent revisions and give support for the proposed synoptical key.

Taxonomic study on Allium dentiferum Webb & Berth. (Alliaceae) and its relations with allied species from the Mediterranean.

Taxonomy and relationships of Allium dentiferum, a polyploid synanthropic Mediterranean species, are assessed based on morphological, karyological and cladistic analysis. A new species, Allium galileum, closely related to A. dentiferum, is described and illustrated. Both species are large and share very long spathe valves, yellow-greenish tepals and interstaminal teeth. The new species, however, is diploid and linked to natural habitats, and is characterized by the lax and spread inflorescence, purple stamen filaments and the smaller perigon, anthers, ovary and capsule. Relationships among these two species and allied taxa of Allium sect. Codonoprasum, such as A. fuscum, A. pallens, A. pani…
