Napier Grass is a robust perennial forming large,
bamboo-like clumps, spreading by short rhizomes; extensive root system
penetrating to 4.5 m. Stems are initially erect/geniculately rising up,
2-4 m tall, 1-2 cm diameter near the base and branched towards the top;
outer stems becoming prostrate extending to 7.5 m and developing
runner-like characteristics, forming plantlets and rooting from lower
nodes. Leaf blades are green, sometimes purple, linear, 30-120 cm long,
1-5 cm wide, tip narrowed; lower surface hairless, upper surface
bristly or papillose-hairy at base, midrib prominent. Inflorescence is
a bristly spike-like panicle 7-30 cm long, 1.5-3 cm wide (excluding
bristles), dense, usually yellow-brown in color, more rarely greenish
or purplish; axis round, velvet-hairy, bearing deciduous clusters of
1-5 spikelets subtended by an involucre, deciduous with the fertile
spikelets; involucral bristles 8-16 mm long, numerous, one prominently
longer bristle, 1-4 cm long; spikelets 5-7 mm long, end spikelet
fertile, nearly stalkless, laterals when present staminate with 1-2 mm
flower-stalks. Napier Grass is native to Sahara to Tropical Africa, to
Arabian Peninsula. It is naturalized in South America, South Asia
including the Himalayas.
Medicinal uses: Raw leaf blades are utilized
in ethnoveterinary medicine practices for treating a range of animals
diseases mainly post-delivery problems in cows and buffaloes.
