Biosystematic researches on Allium cupani group (Amaryllidaceae) in the Mediterranean area.
Allium cupani Raf. is a species complex of the subgenus Allium L., which is taxonomically quite critical mainly for its marked karyological and morphological variability. In the present study, karyo-taxonomic characterization of some peculiar populations of this group from Italian, N African, Balcan and Aegean territories has been performed, using both living plants collected in the field and herbarium material. As a result, ten new species have been recognized and described within the A. cupani complex. They are A. panormitanum from N Sicily, A. samniticum from C Italy, A. mauritanicum from N Morocco and NW Algeria, A. balcanicum from mountains of Balkan Peninsula, A. tzanoudakisanum from …
Pollen morphology and seed germination studies onRetama raetamssp.gussonei, endemic subspecies from Sicily
A study on pollen morphology and seed germination behaviour of Retama raetam (Forssk.) Webb ssp. gussonei (Webb) Greuter, endemic subspecies from Sicily and Calabria, is herein presented, aiming to preserve these populations strongly affected by anthropic pressure.
Allium aetnense (Amaryllidaceae), a new species from Sicily.
A new species from Mt Etna (Sicily), Allium aetenense of A. sect. Codonoprasum, is described and illustrated. It is a diploid species (2n = 16) that grows on basaltic rocks in the mountain belt and shows close relationships with A. tenuiflorum of the Italian peninsula. Its morphology, karyology, leaf anatomy, seed coat microsculpturing, ecology and taxonomic position are examined.
