New combinations in and typification of tropical African species of Urochloa (incl. Brachiaria) (Poaceae)

Abstract

Detailed morphological and molecular research has led to the conclusion that the majority of the species of the genus Brachiaria have to move to the much smaller genus Urochloa. Although many of the necessary new combinations were made, in Africa a fair number of accepted species still do not yet have a name within Urochloa. Following work on West Africa, Central Africa and Madagascar, this paper now provides these new combinations for the remaining sub-Saharan African species, as well as a full synonymy for all East African ones, including typification. In total, the paper deals with 40 species, for 12 of these new combinations are created, while 55 lectotypes and one neotype of both accepted names and synonyms are designated.
