Abstract

Allium occultum Tzanoudakis & Trigas sp. nov. (Amaryllidaceae) from Skiros Island (W Aegean, Greece) is described and illustrated. It belongs to A. sect. Codonoprasum and more precisely to A. paniculatum group. Its closest relatives seem to be A. apergii and A. dirphianum, both endemic to Euboea Island (W Aegean). The new species is currently known from two neighbouring localities of Mt. Kochilas. The tetraploid chromosome number (2n = 32) was found in plants from both localities and according to the karyotype structure, the new species seems functionally diploid.
