The _pedicelled spikelets_ are male and consist of only three glumes.
The _first glume_ is elliptic, oblong, irregularly obtuse, about
11-nerved, margins slightly infolded with long pilose hairs throughout,
more along the margin. The _second glume_ is a little smaller, 3-nerved,
sparsely hairy only along the marginal nerves, folded inwards, and
slightly keeled. The _third glume_ is shorter than the second, hyaline,
nerveless, narrow-lanceolate, acute; _stamens_ are three, with green
anthers, purple-dotted. _Lodicules_ are two, broad and cuneate.
This grass is found flourishing all over India and grows in cultivated
fields and gardens and likes sheltered places. This yields a
considerable amount of fodder and stands cutting well.
_Distribution._ Throughout India in the hills and the plains.

=Andropogon contortus, _L._=
(_Heteropogon contortus_, Beauv.)
This is a tufted perennial.
The stems are erect or slightly decumbent below, slender, rather
compressed towards the base, leafy at the base, simple or branched,
densely tufted and varying in length from 1 to 3 or 4 feet.

The _leaf-sheath_ is smooth or sparsely hairy, compressed and shortly
auricled or not at the mouth. The _ligule_ is short, truncate and
ciliolate.
The _leaf-blades_ are linear, acute or abruptly acuminate, flat, rigid,
sparingly ciliate above, with tubercle-based hairs towards the base,
scaberulous throughout, and 2 to 12 inches long or more, 1/10 to 1/5
inch broad.
The _inflorescence_ consists of a solitary spike with closely
imbricating spikelets.
The _spikelets_ are all on one side, and the lower two to six pairs of
pedicelled and sessile spikelets are all males. The _sessile spikelets_
are all female and awned, except the few lower which are male and
awnless, 1/4 inch long. The _callus_ is long, acute, bearded with
reddish-brown hairs. There are four _glumes_ in the spikelet. The _first
glume_ is narrow, linear-oblong, truncate or rounded, somewhat brown,
many-nerved, hispid, with incurved margins and membranous tip. The
_second glume_ is linear, obtuse, coriaceous, dark-brown, hispidulous,
3-nerved with incurved margins. The _third glume_ is oblong, hyaline,
thin, nerveless, short and truncate. The _fourth glume_ is reduced to an
awn, 3 inches or more in length. The _ovary_ is linear with two long
_stigmas_.
