New Alpine Plants. 111 
32. Carpha nivicola. 
Rhizome creeping; stem very short, smooth; leaves and 
lower bracts broad-linear, blunt, with scabrous margin, flat 
towards the summit; spikelets one-flowered, fasciculate, greatly 
surpassed in length by the leaves; scales of the spikelets 
generally five, unequal, the outer ones twice or three times 
shorter than the rest; the innermost solitary, linear-setaceous, 
teethless, or wanting; bristles of the perigynium six, nearly 
to the top plumose, three times longer than the caryopsis ; 
stamens three; style filiform, puberulous; stigmas three, 
capillary ; caryopsis oblong-triangular. 
On the highest summits of the Australian Alps, near 
swamps. 
Closely allied to C. alpina. As a genus, I consider carpha 
as near allied to oreobolus as to cyathochate, rhynchospora or 
cheetospora. 
GRAMINEAE. 
Most of our new Alpine grasses are already published, but 
IT avail myself of this opportunity to bring a kind of Ehrharta 
under notice, singular for its incomplete flowers. 
33. Ehrharta uniglumis. 
(Sect. Tetrarrhena.) 
Stems branched, with the vagine and leaves scabrous, 
otherwise smooth; spikelets glabrous, distinct, perinath 
nerved, blunt; gimmella of the lower sterile flower a little 
longer than the solitary gluma, and as long as the hermaprod- 
ite flower. 
In humid valleys on the Brodribb River. 
It bears the greatest resemblance to Ehrharta (Tetrarrhena) 
contexta, but differs from this in the equal length of the ste- 
rile flowers, and like from all others in the want of the outer 
glume.
