=Andropogon foveolatus, _Del._=
The stems are slender at first, slightly decumbent at the base and then
erect, covered at base with silkily villous sheaths, branches freely
above before flowering, the lower portion of stems alone being leafy.
The _leaf-sheath_ is somewhat scaberulous, partly green and partly
purplish, always shorter than the internode. The _ligule_ is short,
truncate, hyaline and ciliate. _Nodes_ are tumid and purplish with a
ring of hairs.
The _leaf-blade_ is linear, narrow, sometimes even filiform, acuminate
slightly cordate at the base, scabrid throughout with a few scattered
long bulbous-based hairs near the base to a distance of less than 1/2
inch about it and varies from 2 to 4 inches in length.

1 and 2. Sessile and pedicelled spikelets; 3, 4, 5 and 6. the first,
second, third and the fourth glume, respectively, of the sessile
spikelet; 7. lodicules, anthers and ovary; 8, 9 and 10. the two glumes
and the palea of the pedicelled spikelet.]
The _spikes_ are solitary, 1 to 1-3/4 inch long exserted far above the
small spathiform leaf-sheaths, peduncles are capillary and scaberulous,
pedicels and joints are somewhat flattened, and have along both the
narrow margins long, white, ascending hairs; callus is short with a ring
of short white hairs.
There are two kinds of _spikelets,_ sessile and pedicelled, and both are
oblong-lanceolate and equal. The _sessile spikelet_ consists of _four_
_glumes_. The _first glume_ is lanceolate, flat and smooth, keels
scabrid with usually a deep dorsal pit, 4-nerved. The _second glume_ is
lanceolate, acute, as long as the first, 3-nerved. The _third glume_ is
small, membranous, linear-lanceolate, nerveless. The _fourth glume_ is
the dilated base of the awn, awn is about 3/4 inch twisted to half its
length, scabrid, the lower twisted part dark and the upper pale. There
are three _stamens_ and two _lodicules_. _Ovary_ has two feathery
_stigmas_. The _pedicelled spikelets_ have only two glumes and contain
three stamens. The _first glume_ is oblong-lanceolate, 5-nerved, pitted
above the middle, with recurved margins and scabrid keels and nerves.
The _second glume_ is lanceolate, membranous, hairy at the top, 3-nerved
with margins infolded; _palea_ is oblanceolate, thinly membranous,
nerveless and ciliated at the top; there are three _stamens_ and two
_lodicules_.
This is a fairly common grass occurring all over the Presidency much
liked by cattle and yields plenty of foliage if properly looked after.
It grows on all kinds of soils, even laterite.
_Distribution._--Throughout India.
