Studies in the Ericoideae. III. The genus Grisebachia

Abstract

A revision of the genus Grisebachia Klotzsch in which eight species are recognized is presented. The genus belongs to the Ericaceae-Ericoideae and is endemic in the south-western part of the Cape Province. The work revealed a high degree of variability among the species, necessitating the reduction of seven species to infraspecific rank, seven species to synonomy and the rejection of one species as imperfectly known. One new species G. secundiflora E. G. H. Oliver is described.
