The _sessile spikelets_ are narrowly lanceolate, 3/4 inch long, with
long hairs at the base. The _first glume_ is dorsally hairy, or
glabrous, narrowed from the middle upwards, chartaceous, with incurved
margins and six or seven anastomosing nerves. The _second glume_ is
longer than the first, laterally compressed, ovate-lanceolate,
acuminate, chartaceous, glabrous but often with long hairs on the keel
towards the upper half, 5-nerved, the lateral nerves anastomosing. The
_third glume_ is a little shorter than the second, linear-oblong or
lanceolate, paleate; _palea_ is membranous, nerveless, and encloses
three stamens. The _fourth glume_ is equal to the third glume in length,
membranous, hyaline and divided almost to the middle into two acute
lobes with an awn 1/4 to 3/8 inch long, paleate; _palea_ is lanceolate,
nerveless and encloses three stamens and the ovary and sometimes only
the ovary. The _pedicelled_ _spikelets_ are shorter than the sessile but
with a shorter awn. The _glumes_ are similar to those of the sessile
spikelet; sometimes these spikelets are imperfect or even reduced to a
single glume.
This grass grows well in black cotton soils and sometimes it gets very
well established and then it is very difficult to eradicate it. Cattle
seem to like this grass.
_Distribution._--In black cotton soils all over the presidency, but most
abundant in the Ceded districts.
[Illustration: Fig. 135.--Ischaemum ciliare.]
=Ischaemum ciliare, _Retz._=
It is a tufted perennial grass, erect or creeping. Stems are erect or
ascending, sometimes decumbent at base, and rooting at the nodes, stout
or slender, 6 inches to 2 feet long.
The _leaf-sheath_ is compressed, loose, glabrous or hairy. The _ligule_
is a short, ciliate membrane. _Nodes_ are glabrous or hairy.
The _leaf-blade_ is flat, linear-lanceolate, acuminate, narrowed towards
the acute or rounded base, glabrous or hairy, 2 to 6 inches long and 1/6
to 1/2 inch wide.
The _inflorescence_ consists of two spikes, 1-1/2 to 2 inches long;
joints and pedicels of the pedicelled spikelets equal, hairy at the back
and at the angles.
