The presence or lack of dark pigment in the anther appendages was found to be a useful character that has been overlooked by other authors. The West African high rainfall forest area species, such as A. africana and A. helianthoides are thought to be the most primitive in the genus, while the rhizamatous species such as A. natalensis and A. pluriseta are most advanced. The genus shows weedy habit in Africa, and A. helianthoides an annual, frequently weedy species shows signs of hybridizing. The genus is described and the 21 spp. and some subspecific taxa are keyed. Notes are provided for some of the misunderstood taxa, and the. following new ones described: A. mendoncae (Nyasaland, Ncheu District, Lower Kirk Range); A. gillettii (Ethiopia, Mega Mt.); A. africana (Pers Adams ssp. australis (Angola). The following new combs, are proposed: A. mossambicensis (=Wedelia mossambicensis Oliv.); A. pluriseta Schweinf. in v. Hoehnel ssp. gondensis (=A. gondensis O. Hoffm.); A. natalensis (=Wedelia natalensis Sond.); and A. africana (Pers Adams ssp. magnifica (=Wedelia magnifica Cniov.). A list of insufficiently known spp., rejected taxa, and an index to synonyms are provided.
