There are four _glumes_ in the spikelet. The _first glume_ in the
awnless spikelets is coriaceous, oblong, cuneate, very sparsely hairy or
glabrous, shorter than the second glume, 7-nerved, 5-toothed at the
apex, two teeth being broader and shorter and three sharper and longer.
The _second glume_ is longer than the first, 1/5 inch long,
sub-chartaceous, lanceolate, 3-nerved, 2-fid at the tip and awned or
aristate, margin hyaline and with long brownish hairs on the marginal
nerves. The _third glume_ is hyaline, a little shorter than the second,
lanceolate-linear, tip bifid or irregularly toothed, paleate with two
stamens or rarely empty; the _palea_ is linear, about as long as the
glume, tip irregularly toothed. The _fourth glume_ is hyaline, as long
as the third glume, 2-fid at the tip, awnless with a very minute arista
in the cleft or not, paleate with two stamens; _palea_ narrow and
hyaline. The _first glume_ of the lower spikelets above is somewhat
narrower, 5- or 3-toothed with long hairs at the margins and with tufts
of hairs at the back about the middle. The pedicelled or upper spikelets
also have four _glumes_ and bear one male flower and one bisexual
flower. The _first glume_ is shorter than the second glume, narrow,
oblong, cuneate, 3-toothed with marginal hairs and tufts of hairs at
about the middle at the back, 7-nerved all nerves running straight. The
_second glume_ is longer than the first, 1/5 inch long, sub-chartaceous,
lanceolate, 2-fid at the tip, awned with hyaline margins, 3- to
7-nerved, marginal nerves with long brown hairs, and also with two tufts
of hairs at about the middle or without it. The _third glume_ is
hyaline, nerveless, linear-lanceolate, shorter than the second glume,
tip irregularly toothed or unequally bifid, paleate with two stamens;
_palea_ is linear about as long as the glume. The _fourth glume_ is
hyaline, about 1/6 inch long, lanceolate, 2-fid at the tip, awned in the
cleft, lobes are hairy; _awn_ is 3/4 inch long, paleate, usually
bisexual, rarely female; _palea_ is two-thirds of the glume in height,
broadly ovate or quadrate, lobulate at the apex. _Styles_ are very long,
purple, _anthers_ long, yellow. Grain narrow ellipsoidal or cylindric as
long as the palea.
This grass is found in Chingleput, Nellore and Chittoor districts in
open waste places in loamy soils.
