New Alpine Plants,

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 

 chaitospora. 



Gramineae. 



Most of our new Alpine grasses are already published, but 

 I avail myself of this opportunity to bring a kind of Ehrharta 

 under notice, singular for its incomplete flowers. 



33, Ehrharta uniglumis. 

 (Sect. TetrarrJiena.) 

 Stems branched, with the vagina and leaves scabrous, 

 otherwise smooth ; spikelets glabrous, distinct, perinath 

 nerved, blunt ; gimmella of the lower sterile flower a little 

 longer than the sohtary gluma, and as long as the hermaprod- 

 ite flower. 



In humid valleys on the Brodribb River. 



It bears the greatest resemblance to Ehrharta (Tetrarrhena) 

 contcxta, 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.
