distinguished from C. comans by the flaccid culms; sheathed spikelets, the 
lowest of which is nearly basal; and by the turgid perigynia, which exceed 
the glumes in length. From C. testacea it is at once removed by the number 
of the style-branches, narrower and smoother perigynia, and by the remote 
lower spikelet.

South Island.—-Mountains above the Broken River, and near Arthur’s 
Pass, alt. 3,000-4,500 feet; ravines at the foot of Mount Dobson, and 
between Lake Tekapo and Lake Pukaki, alt. 3,000 feet, T.F.C.; near 
Naseby ; Dunstan Mountains, alt. 8,000 feet; Lake Wanaka, alt. 8,500 
feet, D. Petrie! 
I take this to be a perfectly distinct and well-marked form, easily dis- 
tinguished from any of the species with 8 styles by its usually reddish 
colour ; by the broad sheathing bases to the leaves and their fine points, 
which are curled and twisted when dry; by the small and narrow spikelets, 
all of which are sheathed and stalked, and the lower on filiform peduncles ; 
by the remarkably pale coloured glumes; and by the narrow ovoid or 
elliptic-oblong turgid perigynia, which are quite smooth and even, and of a 
dark brownish- or purplish-black colour. It seems to be conveniently 
placed near C. pulchella although by no means closely allied to that plant. 
From C. testacea and the allied species it is at once removed by the number 
of styles and the shape of the perigynia.

North Island.—Sandy shores near Hokianga, Berggren; near Kaihu, 
Northern Wairoa, T.F.C.; Paparoa, (Kaipara), T. Kirk. 
With this species I am imperfectly acquainted, for although I believe 
that I have gathered it in the Northern Wairoa district, my specimens are 
few in number and very immature. Judging mainly from Dr. Berggren’s 
plate and description, it is separated from the allied species with three 
stigmas by the slender habit, filiform plano-convex leaves, which are longer 
than the culms, remote short-stalked or sessile spikelets, and by the narrow 
plano-convex perigynia, with the margins sharply and coarsely toothed 
towards the apex. 
Near Lake Tekapo, Canterbury, I have collected specimens of a plant 
. Closely allied to the above, but differing in the stouter habit, much larger 
and broader glumes with longer awns, and rather broader perigynia. I had 
placed it as a variety of C. comans, but Mr. J. G. Baker, of Kew, who has 
done me the favour of comparing it with an authentic specimen of C. comans 
received from Dr. Berggren, considers it to be distinct. I hesitate, however, 
to describe it as new until better acquainted with Berggren’s plant,
