The genus Amphiglossa (Gnaphalieae, Relhaniinae, Asteraceae) in southern Africa

Abstract

It is proposed that the generic concept of Amphiglossa DC. be broadened to include the genus Pterothrix DC. The two gen­era were previously separated on the presence or absence of ray florets. A thorough study of various characters showed that the type of florets was overemphasised in the past and that the pappus and cypselas provide sufficient evidence to unite the two genera The genus consists of 11 species of which  Amphiglossa celans Koekemoer.  A. grisea Koekemoer,  A. rudolphii Koekemoer and A. susannae Koekemoer are newly described A key to the species as well as detailed descriptions and distribution maps are provided. Photographs are included for each species and key characters for the genus are also illustrated.
