Cenchrus nodiflorus (Franch.) Zon, 2019

Cenchrus nodiflorus (Franch.) Zon View in CoL , comb. nov.

During the preparation of the Gramineae of West and Northern sub-Saharan Africa (WNSA, http://grasses-africa.linnaeus.naturalis.nl/linnaeus_ng/) new taxonomic insights in the delimitation of genera were encountered. Recent molecular phylogenetic studies ( Chemisquy et al. 2010) have led to the amalgama- tion of the genera Cenchrus L. and Pennisetum Rich. and the inclusion of most of the species of Brachiaria (Trin.) Griseb. in the genus Urochloa P.Beauv. ( Veldkamp 1996, Sosef 2016). The generic names of Cenchrus and of Urochloa have priority and so the species of Pennisetum and most of Brachiaria need to be transferred to them. Recently, Verloove (2002) and Sosef (2016) made new combinations, but a number of new combinations for species in the West African region still needs to be made. Therefore, nine new combinations are presented here, of which seven are lectotypified.
