other.

This grass is a very slender one and it is closely allied to _Gracilea
nutans_. It differs from _G. nutans_ in being an annual and in having
filiform leaves, bicuspidate third glume which is scabrid all over the
back and a fourth glume distinctly tricuspidate at the apex. This does
not occur so widely as _Gracilea nutans_.

_Distribution._--Bellary and Chingleput districts, the Punjab,
Rajputana, Concan and Kanara.

34. Enteropogon, _Nees._

Tall slender grasses with very long narrow leaves. Spikelets are
2-flowered, narrow, biseriate, unilateral, imbricate on the rachis of a
solitary spike; the rachilla is elongate between the flowering glumes
and produced beyond them and terminates in a rudimentary awned glume.
There are four glumes. The first two glumes are hyaline, unequal-nerved
and persistent. The third and the fourth glumes are chartaceous,
narrowly lanceolate, 3-nerved, bicuspidate and awned below the tip; awns
are capillary, straight; the callus is bearded and articulate at the
base. The third glume bears a bisexual or female flower and the fourth
bisexual or male. Lodicules are two. Stamens are three with long
anthers. Styles short diverging from the base, with short stigmas
laterally exserted.

=Enteropogon melicoides, _Nees._=

This is a tall perennial grass with stout roots. Stems are densely
tufted on a short woody root-stock, erect, leafy, 1 to 3 feet long.

_Leaf-sheaths_ are compressed and distichous below, glabrous or
sometimes with a few hairs close to the margin. Ligule is a ridge with
long hairs.

The _leaf-blade_ is very long 1/6 to 1/4 inch broad, auricled at the
base, narrowed into very finely acuminate or capillary tips midrib
prominent; scaberulous on both the surfaces and with long hairs on the
auricles.

The _spikes_ usually solitary, but occasionally binate, 6 to 10 inches
long; rachis is quite smooth and dorsally rounded.

The _spikelets_ are about 1/4 inch long, erecto-patent. There are four
_glumes_. The _first glume_ is lanceolate, 1-nerved, and persistent. The
