Introduced and widely spread in India and America. Known in Brazil as 
“ Capim (grass) de Angola,'’ which name is, however, also applied to other 
grasses. It is commonly cultivated in the tropics under the name “ Guinea 
grass ” and has the reputation of being one of the best fodder grasses of the 
tropics. Apart from the more acute or blunt tips of the spikelets and their 
glabrous or pubescent condition the species is very uniform. The specimens 
with pubescent spikelets have been marked with an * in the enumeration. This 
state has been distributed as P. trichoglume by K. Schumann {Holst, 8716) and 
noted as P. maximum, var. trichoglume by Eyles. Its incidence and distribution 
hardly suggest a definite and geographically fixed variety. 
7. P. infestum, Peters, Reise Mozamb. Bot. 546 (name only). 
Perennial, up to over 4 ft. high, compactly tufted on a very short 
rhizome with intravaginal innovations. Culms erect or geniculately 
ascending, rather slender (not much over 1 lin. in diam.) 4-5-noded, . 
sparingly branched with long erect branches, compressed below, 
terete above, usually softly hairy below the nodes, hairs spreading 
or subappressed, sometimes very long. Leaf-sheaths tight, the lower 
much compressed, strongly keeled, up to over 6 in. long, the upper 
terete below but keeled upwards, all finely striate or more strongly 
so at the base and more or less softly hirsute to almost villous, 
particularly towards the densely bearded nodes, or the uppermost 
glabrous upwards, but mostly with a band of hairs or a beard at the 
junction with the blade ; ligules very short, membranous, truncate, 
silkily ciliate ; blades erect., linear from a long and often much 
attenuated folded and keeled base, flat above the latter, tapering'
