A wiry, smooth Sedge, with long, creeping, rigid, almost woody, rooting, scaly cnlms, that run amongst the
sand and ascend, bearing many curving leaves, with scarious sheathing bases. Leaves a foot long, much longer than
the culms. Spikes close together, shortly peduncled, erect, thick and broad when ripe, with few, very large, pale-
brown carpels, and long, leafy, rigid bracts.—Also found in New HoUand and Tasmania.

slender peduncles, the lower drooping. l - 2 i inches long, i inch diameter. Scales anà perigynia deciduous, loosely

A very handsome, taU Sedge, 2 -4 feet high, resembUng C. fascicularis in habit and general appearance, differing
ill wanting the terminal male spike, very variable in tbe size of aU its parts, of a pale colour. Leaves i - 4 inch
broad, with three strong nerves, much longer than the culms. Spikes 1 ^ 3 inches long, pale yellow-brown,
subereet, nodding or drooping, squarrose from the diverging or recurved, ovate lanceolate, bifid, pale perigynia,
wbich are as long as the cuspidate scales, and become dotted in age. Brads long, broad, and leafy.
Obs. The C. appressa, Br., of Lord Auckland’s Group, is erroneously stated (Fl. Antarct. p. 91) to be a native
of New Zealand. I t much resembles C. 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.

A remarkable genus, containing about thirty species, most of which are natives of damp climates in south
temperate latitudes, as Australia. New Zealand, Chile, etc. A few are found in Tropical America. The genus
differs from Carex only in the curious flat appendage to the female flower : this is inserted below the ovary, projects
beyond tbe perigynium, and is hooked at the tip ; its exact nature is obscure, but it probably represents a
coiitiuuatiou of tbe axis of tbe flower. (Name from oyfcivov, a small Jiook.)
