Two new taxa of Geigeria (Asteraceae, Inuleae) from Angola, with a multivariate analysis of Geigeria aspalathoides

Abstract

Comparison of the morphological characters of specimens of Geigeria aspalathoides (Asteraceae, Inuleae), with the aid of cluster analysis, indicates the existence of two subspecies endemic from Angola: subsp. aspalathoides and subsp. chorleyana. In addition, we describe a new species of this genus, Geigeria decurrens, from Angola.

An outline of the genus Geigeria (Asteraceae, Inuleae)

“…We recognize two subspecies of this species (Ortiz et al 2000). The most characteristic morphological types of these taxa differ very markedly, which might be taken to indicate species status; however, intermediate forms exist [Angola, Gossweiler 4 177 (BM), specimen at the right; Angola, Gossweiler 3553 (BM)].…”
