South Island. —Summit of Mount Arthur, Nelson, alt. 5,000-6,000 feet ; 
Raglan Range and mountains flanking the Wairau Valley, 5,000-6,000 feet ; 
mountains above Arthur’s Pass, Canterbury, alt. 3,500-6,000 feet; Mount

Usually from 8 to 9 inches high, but taller specimens are sometimes 
seen, The leaves are described by Hooker as “longer than the culms,” 
but this is only the case in the flowering stage, the culms elongating 
considerably as the fruit ripens. All my New Zealand specimens have the 
style nearly constantly 2-branched, in this respect differing from numerous 
European and American specimens that I have examined, and in which the 
style is nearly uniformly 3-branched. They thus approach the Australian 
C. cephalotes, F.v.M., which, judging from examples kindly forwarded by 
Sir Ferdinand Mueller, can only be separated from our plant by the broader 
and flatter, hardly stipitate perigynia, and might well be regarded as a 
variety only. 
C. pyrenaica has an extensive range out of New Zealand. It is found 
on the high lands of Northern and Central Europe, Northern Asia, and in 
America along the line of the Rocky Mountains from Alaska to Utah and 
Colorado.

| North Island.—Tops of the Ruahine Mountains, Colenso (Handbook). 
South Island. —Not uncommon in the mountains of Nelson and Canter- 
bury, alt. 2000-5000 feet. Otago, mountains above Lake Harris, T. Kirk. 
Also in Tasmania and Victoria. 
A well-marked species, easily distinguished from the preceding by the 
strict and nearly terete leaves, shorter spikelets, and erect subulate bract. 
It varies greatly in size, and in the number of flowers in the spikelets, but 
its other characters appear to be fairly constant. 
Section II. Spikelets several or many, androgynous or rarely dicecious, 
sessile, forming a compact or more or less interrupted sometimes paniculate 
or decompound inflorescence. Stigmas 2. :
