bovate-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.

ovary; 7, 8 and 9. the glumes of the pedicelled spikelets in order.]
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.
The _sessile spikelets_ in the upper part of the spike are bisexual,
lanceolate, 1/6 inch long and those in the lower part of the spike are
shorter, obtuse, male. The callus is short and bearded. There are four
_glumes_. The _first glume_ is ovate or obovate-oblong, dorsally flat or
nearly so, with a deep narrow-longitudinal median furrow usually below
the middle and answering to a ridge on the ventral face, obtuse or
2-toothed at the apex, margined above the middle, with a hyaline,
narrow, finely denticulate w
