Grasses -- India, South; Plants -- India, South
The _pedicelled spikelets_ are somewhat longer than the sessile 1/3 to
1/2 inch, with very short pedicels. The _first glume_ is lanceolate,
obliquely twisted, hispid at the back with long bulbous-based hairs,
margins more or less unequally winged. The _second glume_ is oblong
lanceolate, acuminate, 5-nerved, thinly ciliate with hyaline margins.
The _third glume_ is oblong, hyaline, 1-nerved and ciliate. The _fourth
glume_ is obovate-oblong or oblong, hyaline, ciliate, nerveless. There
are three _stamens_.
This grass though coarse forms very good hay if cut before it flowers.
The only objection against this grass is the presence of the troublesome
awns which get twisted together like the strands of a rope. This is the
_spear grass_ of the Anglo-Indians. It grows all over the Presidency and
is a troublesome weed when in flower.
_Distribution._--All over the Presidency and India. Common in all
tropical countries.
=Andropogon Schoenanthus, _L. Var. caesius._=
(_Cymbopogon caesius_, Stapf.)
This is a perennial grass with stout or slender, erect stems rising from
a woody base, leafy upward, simple or branched.
The _leaf-sheath_ is smooth and glabrous. The _ligule_ is an
oblong-ovate membrane. _Nodes_ are glabrous.
The _leaf-blade_ is long, narrow or broad, narrowly linear-lanceolate,
finely acuminate, glaucous especially beneath, thinly coriaceous,
glabrous on both the surfaces, base rounded or cordate and amplexicaul,
6 to 10 inches by 1/6 to 1/3 inch.
The _panicle_ is elongate, leafy, narrow, dense or interrupted, compound
or decompound, 1 to 2 feet long; bracts are lanceolate, spathiform,
finely acuminate, glabrous, varying in length from 1 to 1-1/2 inches,
and with hyaline margins; the proper bracts are as long as the spikes or
longer.

The _spikes_ are unequal, 1/2 to 2/3 inch long, one 3- to 4-jointed and
the other 4- to 6-jointed; the joints and pedicels are narrowly clavate,
half as long as the sessile spikelets, tips dilated and toothed, margins
villously ciliate, with long hairs.
The _spikelets_ are binate, one sessile and the other pedicelled.
