H a b . Northern Island ; in woods, etc., frequent. Banks and Solander, Smclaw, etc.
A very similar species to 0. disdta, indistinguishable from it in general appearance, but the perigyma are only
toothed at the mouth, not divided into two prongs, like a fork, as in that species.

13ab. Northern Island; common m moist woods. Banks and Solander, ete.
A more rigid, harsh species than C. dissita or 0. Lamlertiana, with smooth, nerved leaves. Oalms 1 ^ 2 1 feet
high, slender, shorter than the leaves, which are three lines broad. Spikes five to nine, pale brown, slender, on long
slender peduncles, the lower drooping, 1-2* inches long, * meh Gameter. Seales perigynia deciduous, loosely-
imbricated, the former lanceolate, narrowed into a long hispid awn ; the latter spindle-shaped, bifid, and strongly
nerved. Bracts long and leafy.

H ab . Northern and Middle Islands ; abundant in moist woods. Banks and Solander, etc.
A very handsome, tall Sedge. 2-4 feet high, resembling C. fascicularü in habit and general appearance, differing
in w'anting the termmal male spike, very variable in the size of all its parts, of a pGe colour. Leaves *-* inch
broad, with three strong nerves, much longer than the cGms. Spikes l* -3 mches long, pGe yellow-brown,
suberect. nodding or drooping, squarrose from the diverging or recurved, ovate lanceolate, bifid, pale perigynia.
which are as long as the cuspidate scGes, and become dotted in age. Brads long, broad, and leafy.
Obs. The C. appressa, Br., of Lord Auckland’s Group, is erroneously slated (El. Antarct. p. 91) to be a native
of New Zealand. It much resembles 0. virgata, but is a more robust, broader-leaved plant ; and being found in
Tasmama also, it will, in all probability, be found in the southern parts of New Zealand.

Omnia Cariéis, sed perigynium fl. foem. seta hypogyna exserta apice hamata auctiim.
A remarkable genus, containing about thii-ty species, most of which are natives of damp climates in sonth
temperate latitudes, as Australia, New Zealand. Chile, etc. A few are foimd in TropicG America. The genus
differs from Carex only in the curious flat appendage to the female flower ; this is mserted below the ovary, projects
beyond the perigynium, and is hooked at the tip ; its exact nature is obscure, but it probably represents a
coiitiuuatiou of tlie axis of the flower. (Name from oyKtvos, a small hook.)
