Crepis lacera is a diploid species (2n = 8), mostly occurring in Italy, with a disjunct population in Albania. The names C. lacera, C. latialis and C. lacera f. titani are here lectotypified, and their taxonomic value is discussed. For the latter name, based on morphological, biogeographical and karyological results, we propose here the subspecific rank (C. lacera subsp. titani stat. nov.). In addition, basal leaf morphology variation, the main distinguishing feature between the two subspecies, is discussed in the light of paedomorphosis, and a distribution map for both subspecies is presented.

Abstract

Crepis lacera is a diploid species (2n = 8), mostly occurring in Italy, with a disjunct population in Albania. The names C. lacera, C. latialis and C. lacera f. titani are here lectotypified, and their taxonomic value is discussed. For the latter name, based on morphological, biogeographical and karyological results, we propose here the subspecific rank (C. lacera subsp. titani stat. nov.). In addition, basal leaf morphology variation, the main distinguishing feature between the two subspecies, is discussed in the light of paedomorphosis, and a distribution map for both subspecies is presented.
