ng as itself or shorter, keeled and
with short stiff bristles on the keel and on the sides above the middle.
The _third glume_ is hyaline, narrow, obtuse, shorter than the second,
2-nerved, ciliate. The _fourth glume_ is the linear, hyaline, 3-nerved
base of the awn; the _awn_ is 1-1/2 to 2-1/2 inches and bent at about
the middle.

The _pedicelled spikelets_ are about 1/3 inch, narrowly lanceolate, male
or neuter and with short rusty hairs on both the margins of the pedicel
and a semi-circular tip. The _first glume_ is thin, 2-toothed or not at
the tip, awned, _awn_ being as long as itself or longer, 7-nerved,
ciliate at the sides from base to tip; the nerves are either equidistant
or the lateral nerves nearer the margin. The _second glume_ is
lanceolate-acuminate, not awned, 3-nerved, margins hyaline, and
ciliolate. The _third glume_ is hyaline, linear-oblong, 2-nerved,
ciliolate. The _fourth glume_ is linear or linear-lanceolate, hyaline,
nerveless or 1-nerved.

This grass grows abundantly on the sides of the Kambakkam Drug,
Chingleput district, and in Penchalkonda, Nellore district, and seems to
be an endemic species. It is usually confined to the hill sides and not
found in the plains. This grass is very closely allied to _Andropogon
Wightianus_ and it differs from it only in the general habit of the
plant and in having bristles on the leaf-sheaths. On the whole this is a
coarser and larger plant than _A. Wightianus_.

_Distribution._--Kambakkam Drug in the Chingleput district and
Penchalkonda in Nellore district.

=Andropogon Wightianus, _Steud._=

(_Chrysopogon Wightianus_, Nees.)

This is a perennial. Stems are erect or ascending from a creeping
root-stock, varying in height from 2 to 3 feet.

The _leaf-sheath_ is flattened, softly hairy or glabrous, often ciliated
near the mouth. The _ligule_ is a fringe of very short hairs.

The _leaf-blade_ is narrowly or rarely broadly linear, obtuse or acute
and abruptly mucronate, or narrowly drawn into a point glabrous or
pubescent, margins shortly ciliate.

The _panicle_ is narrow, 3 to 6 inches long, peduncle smooth below but
thinly pub
