Brachiaria Griseb.


Description from Flora of China

Panicum sect. Brachiaria Trinius, Gram. Panic. 51, 125. 1826.

Annual or perennial. Leaf blades linear to lanceolate, often with cartilaginous margins. Inflorescence composed of racemes along a central axis; raceme rachis triquetrous or flattened, sometimes winged; spikelets sessile or pedicelled, single or paired, rarely in fascicles or on secondary racemelets. Spikelets plump, usually elliptic, florets 2; lower glume adaxial, varying in length from very small and veinless to many-veined and subequaling spikelet, base sheathing, sometimes extended downward as a short stipe; upper glume and lower lemma similar, as long as spikelet, membranous or cartilaginous; upper lemma coriaceous, smooth, striate or rugose, margins inrolled, apex obtuse to acute, occasionally minutely mucronate; upper palea apex tucked within lemma. x = 7, 9.

Brachiaria is sometimes included within Urochloa, but usually they can be distinguished without difficulty.

About 100 species: tropics and subtropics mainly of the Old World, especially Africa; nine species (one endemic) in China.
