Guinea grass is a densely clustered perennial grass
with stems 0.8-3 m tall, erect or rising up, often branched, the nodes
usually bearded. Leaf-blades are linear, 10-60 cm long, 0.4-2 cm wide,
flat, hairless, long-tapering to a fine point; lowermost sheaths
strongly compressed and keeled. Flower panicles are ovate, 10-45 cm
long, contracted or open, the branches mostly bare in the lower half,
the lowermost prominently whorled. Spikelets are oblong, 2.5-3.6 mm
long, hairless or shortly and densely velvet-hairy, pointed or
subblunt; lower glume round, hyaline, a quarter to a third the length
of the spikelet, rounded or shortly pointed, 1-3-nerved or sometimes
almost nerveless; upper glume 5-7-nerved; lower lemma 5-7-nerved, its
palea almost as long; upper lemma pallid, rugulose. Guinea grass is
native to Tropical & S. Africa. It was introduced in India as a fodder
grass, and is now naturalized. It is also found in East Himalaya.
Flowering: June-October.
Medicinal uses: Guinea grass is used in the
treatment of heartburn and tympanitis. Sap from the crushed fresh plant
is used as a cicatrisant on wounds and sores. The grass is tied around
the head in order to bring relief from a headache.
