Abstract
An analysis of the qualitative and quantitative characters of Allium sphaerocephalon group in Western Mediterranean is presented. Allium durandoi is considered to be conspecific with A. ebusitanum, of which it becomes a synonym. A map of this species and a key to the group is provided.
Highlights
The genus Allium L. comprises 500-600 species, which are mainly distributed in the northern hemisphere (Wilde-Duyfjes, 1977)
The “Sphaerocephalon Group” could be recognized by bulbs with non reticulate-fibrous tunics hollow leaves and persistent spathe, with two segments. This group includes 12 species widespread around the Mediterranean from Portugal and Morocco to SE Ukraine, E Turkey and Egypt (Mathew, 1996). Four of these species are present in Western Mediterranean: A. ebusitanum Font Quer, A. melananthum Coincy, A. pruinatum Link ex Spreng., and A. sphaerocephalon L
Some well-preserved specimens of each species were selected as OTUs: 10 specimens of A. ebusitanum, 6 of A. durandoi, 10 of A. melananthum, 9 of A. pruinatum and 15 of A. sphaerocephalon (Appendix 1)
