Distribution — Native to much of southern Africa, from the Republic of the Congo and the Democratic Republic of the Congo east to South Sudan and Ethiopia, south to South Africa, also in Madagascar; introduced in Ghana and a fair number of counties in South and Central America.

Nomenclatural notes — Sosef (2016) discussed its distinction from the closely related U. mutica (Forssk.) T.Q.Nguyen. Vorontsova (2022) provides a detailed description and dis- cusses its presence in Madagascar.

The syntypes of Panicum multifolium could not be located at B, and were most likely lost during the WWII fire. No duplicates were found in several other herbaria (amongst which G, GOET, K, W), but since our search was not exhaustive, and hence an isotype may still be traced elsewhere, we decided to not yet designate a neotype.

Camus (1954) indicated a single collection at P to be the type of Brachiaria arrecta var. madecassa . However, there are two duplicates available of which we have chosen one to be the lectotype.
