This is principally distinguished from C. testacea by its smaller size ; 
shorter and stouter culms; and more strongly nerved biconvex perigynia. 
It is usually from 6 to 12 inches high, but alpine specimens are much 
depauperated, only 2 or 8 inches high, bearing two or three short and stout 
spikelets sunk amongst the leaves.

A curious little plant, first discovered by Dr. Berggren, and excellently 
described and figured by him. Its only near ally is the following species :—

South Island.—Vicinity of Lake Tekapo, Canterbury, alt. 2,500 feet.

This is near to C. cirrhosa, but differs in its larger size and stouter 
habit; broader glumes ; larger more turgid perigynia, with shorter beaks 
and serrate margins; and in having 3 stigmas. The nut is trigonous, 
while it is lenticular in all the fruiting specimens of C. cirrhosa that I have 
examined. Old tussocks of this species often have a most peculiar appear- 
ance. The centre dies out, leaving a hollow ring which grows on 
vigorously. In dry weather the leaves all curve inwards towards the centre 
of the ring, giving the tussock the appearance of a cushion with a low centre.

Differing much in habit from the two preceding species, never forming 
close compaet tufts, but having more of the habit of small and fine leaved 
specimens of C. breviculmis. Besides this, the culms and leaves are much 
more slender, spikelets smaller, and the perigynia of a very different shape, 
being trigonous or almost fusiform, or, to take a familiar example, very 
near to those of C. lucida in shape. As I only have it from one locality, 
some little allowance must be made for the description. Small specimens 
are often hardly more than an inch or two in height, but large ones attain 
5 or 6 inches.

I am not in a position to add anything to Dr. Berggren’s description of 
this species, for although I am inclined to refer to it some specimens of a 
plant gathered in the Wairau Valley, Nelson, they are much too imma- 
ture to warrant a positive conclusion. Dr. Berggren remarks that it is
