Nomenclatural notes — The protologue of Panicum gossypinum states that the species is based on Eriochloa purpurascens Hochst. ( Hochstetter 1841) , an invalid name (nom. nud.) and an unnamed variety of Panicum holosericeum . It cites two collections, Schimper 175 (an obvious error for #174, which matches the description and locality data in all aspects) and Schimper 1196. We have chosen the first as the lectotype, because the second is also the (lecto)type of Panicum comatum (= Urochloa comata ).

The protologue of Panicum nigropedatum var. basipiliferum clearly mentions Bovone 29 as the type, but the specimen with this number at TO (a syntype of Panicum brizanthum var. lasiochloa , see below U. brizantha ) does not match with the locality and date provided by the protologue. Hence, the whereabouts of the type is uncertain.

The protologue of Brachiaria brachylopha mentions a fair number of specimens. We have chosen one present at Kew, where Stapf worked and which carries the name written by Stapf, as lectotype. It has several duplicates, some of which erroneously carry the number 1392.
