perigynia are sharply serrate. I find that the male spikelet is not unfre- 
quently partly female, a point not alluded to by Dr. Berggren, whose 
description and plate are otherwise very accurate. 
19. C. raoulii, Boott, in Hook. fil. Fl. Nov. Zeal., i., 988. Yellowish or 
dark green. Culms rather stout, laxly tufted, 9 inches to 2 feet in height, 
triquetrous, scabrid. Leaves usually longer than the culms, 1-1 inch broad, 
flat and grassy, grooved, coriaceous, margins scabrid. Bracts long and leafy. 
Spikelets 4-7, pale, stout, erect, approximate and sessile, or the lower ones 
distant and shortly pedunculate, 3-1 inch long, + inch broad; all female 
but usually with a few male flowers below, the uppermost generally longer 
with more male flowers below. Glumes pale brown, broadly ovate, thin 
and membranous, 3-nerved, deeply bifid, awn long, stout and hispid. Peri- 
gynia broader and longer than the glumes, elliptical, narrowed to the base 
and upwards into a rather long and stout 2-toothed beak, strongly nerved, 
unequally biconvex; margins serrate above. Stigmas 2. IU. Car., iii., 
109, t. 333; Hook. fil. Handbk. N.Z. Flora, 314. C. goyeni, Petrie, Trans. 
N.Z. Inst., xiv., 363. 
South Island.—Not uncommon in mountain districts. Nelson—Graham 
River, Wangapeka Valley, Mount Owen, ete.: T.F.C. Canterbury—Akaroa, 
Raoul; Southern Alps, Sinclair and Haast; Broken River basin, Upper 
Waimakariri; Lakes Tekapo and Pukaki; T.F.C. Otago—head of Lake 
Wakatipu, D. Petrie!; near Lake Wanaka, J. Buchanan! Altitudinal 
range from 250-3,000 feet. 
Although C. raoulii is one of the most distinct species of the genus in 
New Zealand, there has been considerable misconception respecting it, and 
by many it has been confounded with C. testacea. I therefore give revised 
descriptions of both species. Its main characters lie in the loose open 
habit, comparatively broad flat leaves, in the terminal spikelet being always 
partly female, and in the elliptical strongly nerved and serrate perigynia, 
which are unequally biconvex, and narrowed both upwards and downwards. 
In C. testacea the perigynia are much broader, plano-convex and almost 
hemispherical, and in addition to the very different habit the terminal spike- 
let is never mixed with female flowers. 
20. C. devia, Cheeseman, Trans. N.Z. Inst., xv., 801. 
South Island.—Mountain districts in Nelson, not uncommon above 2,500 
feet: T.F.C. 
Allied to C. testacea, but readily distinguished by its different habit, 
stouter culms, rigid and coriaceous grooved leaves, very stout clavate male 
spikelets, and more turgid biconvex perigynia, with a shorter broader beak 
and entire margins.
