This is a perennial grass closely resembling _Iseilema laxum_ in its
habit, but shorter, stouter and branching more freely. The leaf is
similar to that of _I. laxum_ in all its parts.

1. A cluster of spikelets with spathes; 2. the involucral and the inner
spikelets; 3. the inner spikelets; 4 and 5. the glumes of the involucral
spikelets; 6, 7, 8 and 9. the four glumes, respectively, of the sessile
spikelet; 10. ovary; 11 and 12. glumes of the inner pedicelled
spikelets.]
The _pedicelled spikelets_ of the involucel have firmer harder, shorter
and broader pedicels, thickly bearded and consist of two glumes only.
The _first glume_ is very strongly 5-nerved, coriaceous,
oblong-lanceolate; with scaberulous infolded margins, with long cilia.
The _second glume_ is lanceolate, thin, 3-nerved, glabrous. The inner
_pedicelled spikelets_ are similar to the pedicelled spikelets of the
involucel. The _sessile spikelet_ has four glumes. The _first glume_ is
elliptic-lanceolate, apex drawn into a long narrow strip ending in two
teeth or truncate, sparsely ciliate at the margins about the middle,
faintly 3-nerved. The _second glume_ is shorter than the first,
lanceolate, drawn out into an acuminate point at the apex, hairy at the
back. The _third glume_ is hyaline, short, oblong, apex broad and
irregularly toothed, nerveless. The _fourth glume_ is an awn.
This is very common in the Deccan districts and grows on all kinds of
soils. This is a good fodder grass.
_Distribution._--Very common in the Ceded districts and Nellore.

TRIBES V AND VI--AGROSTIDEAE AND CHLORIDEAE.
The tribe =Agrostideae= is a very small one. It is represented in South
India only by a few genera. The spikelets are usually 1-flowered and the
rachilla is jointed at the base just above the empty glumes and it is
not produced beyond the flowering glume. There are only three glumes in
the spikelet.
Sub. Tribe 1. =Stipeae=.--The spikelets are narrow and long, panicles and
the flowering glumes are rigid or hard, and awned.
The third glume is narrow, long, awn 3-fid 31. Aristida.
Sub. Tribe 2. =Euagrosteae=.--The spikelets are very small, in open or
contracted panicles.
The third glume is thin and membranous, awnless. 32. Sporobolus.
=Chlorideae= is also a small tribe with about ten genera, most of them
being very common in Southern India. The spikelets are unilaterally
biseriate on the rachis which is not jointed at the base. There are one
or more flowers in the spikelet, all or only the lowest being bisexual.
The rachilla is jointed just above the empty glumes and it is produced
or not beyond the flowering glumes. The inflorescence consists of
spikes, or spiciform racemes, solitary or digitate, and in some it is
paniculate.
Rachilla produced beyond the flowering glume.
Spikes usually solitary.
