Phylogenetic species delimitation unravels a new species in the genus Sclerorhachis (Rech.f.) Rech.f. (Compositae, Anthemideae)

Sclerorhachis is a small genus and belongs to subtribe Handeliinae of tribe Anthemideae (Compositae). While according to the Flora Iranica only two species of the genus are indicated for Iran (i.e. S. platyrachis and S. leptoclada), the genus constitutes a taxonomically very interesting group here due to the presence of several isolated populations deviating from others morphologically. In the present study, we have used phylogenetic analyses as...
