Résumé : |
"Morphological data has been assembled from a large collection of fruiting heads of the Hordeum murinum aggregate. Computer analysis reveals two major taxa, which, using seven characters, can be readily separated. These are recognized as H. murinum L. and H. leporinum Link. The former is primarily north‐western and the latter south‐eastern in distribution. Both plants can occur sympatrically, and there is no evidence of a cline.
Diploid plants from south‐east Europe represent extreme H. leporinum types and these are recognized as a subspecies (H. leporinum Link ssp. glaucum (Steudel) Booth & Richards) stat. et comb. nov. Hexaploid plants of H. leporinum cannot be morphologically differentiated." (source : auteurs) |
