I am not possessed of any other description of Swartz's A. sac- 
charoides than the specific character, as it stands in Willdenow’s 
edition of the species, which agrees with my plant; I therefore cone 
clude they are the same.

Spikes from six to eight, fascicled, peduncled ; rachis hairy. Flow- 
ers lanceolate, hermaphrodite, sessile and awned; male pedicelled — 
and awnless ; ; calyces acute, exterior valve hairy. ; 
A native of Coromandel. Itis a stout erect species, with a branch 
from the axil of each of the superior smooth short leaves; it has 
much the appearance and habit of Bladhii, and pertusus; from 
the former it differs. most conspicuously in the valves of the caly- 
ces being acute, whereas in Bladhii they are broad and rounded ; 
and from’ pertusus in the want of the pit on the back of - exte- 
rior valve of the hermaphrodite flowers. i 
“er. A. punctatus. R. | 
: Erect, simple. Leaves large, long, and numerous. Panicle of 
numerous, simple, secund ramilications. Exterior valves of the 
calyces of both hermaphrodite and neuter flowers pitted. 
This is a mountain grass. 
|. Culms from two to four fee: high, without branches, below bent 
towards the earth for half a foot, often erect, entirely surrounded 
with the sheaths of the leaves; not piped, but replete with spongy 
pith.— Leaves numerous cies with some long white hairs scattered 
over them near the base ; mouths of the sheaths supuled, bearded, 
and woolly, — Panicle erect, oblong, from four to five inches high, 
composed of many, erect, short-peduncled, filiform, secund, spiked 
racemes; rachis and flowers exactly as in A, fascicularis ;- except 
that bus the outer valve of the calyx of both flowers has a pitin the 
middle.—The coro] of the hermaphrodite flower wants the inner 
valve, i in its place is a pretty long twisted awn.
