This is a short, stout perennial grass with stems rooting at the nodes;
branches are flat, short, densely leafy, 2 to 6 inches long.
The _leaf-sheaths_ are smooth, equitant with thinly membranous margins.
The _ligule_ is a ciliated ridge.
The _leaf-blade_ is flat, linear, distichous, coriaceous, rounded at the
tip, margins sparsely ciliate, 1 to 2-1/2 inches long.
The _inflorescence_ is a terminal raceme, 1/2 to 2 inches long, half
hidden by the uppermost leaf-sheath, the peduncle is flattened and 1 to
2-1/2 inches long; rachis is also flattened with a tuft of long silky
hairs at the base.

The _spikelets_ are shortly pedicelled or sessile, dorsally compressed,
cuneiform, about 1/3 inch, glistening, villous, not articulate at the
base, 2- to 3-flowered, rachilla is narrowed downwards, resembling a
callus and villous, jointed at the acute base above the empty glumes,
and crowned with broad obconic empty awned glumes. The spikelets have
usually seven, rarely eight glumes. The _first_ and the _second glumes_
are narrow, membranous, glistening, empty and persistent and the others
are coriaceous with membranous margins. The _first glume_ is linear or
linear-lanceolate, acuminate, 1-nerved, scaberulous along the nerve. The
_second glume_ is longer than the first, oblong-lanceolate, acuminate,
narrowed towards the base, inserted much above the first glume and
embracing the rachilla, 3-nerved, scaberulous along the mid-nerve at the
base only. The _third_ and _fourth glumes_ are half-amplexicaul, empty,
epaleate, flabelliform, 4-lobed, 7-nerved, shortly awned at the back,
villous; the side lobes are acuminate or aristate and the central lobes
are shortly awned. The _fifth_, _sixth_ and _seventh glumes_ are
obovate-cuneate, 7- to 9-nerved, paleate, flower-bearing and 3-lobed,
the side lobes are acuminate and the central lobe is bifid and dorsally
awned; palea is ovate-acute, 2-nerved and ciliolate. The _eighth glume_,
if present, is neuter and imperfect, 3-lobed and shortly awned.
_Lodicules_ are minute. _Stamens_ are two or three with small anthers.
Grain is oblong, compressed, reddish brown.
This grass generally grows in gravelly and somewhat alkaline soils. So
far this has been noticed and collected in Chingleput and Nellore
districts.
_Distribution._--Mysore and the Carnatic, and Ceylon.
