A tall, rigid, squarrose, excessively harsh plant, allied to Holosclicenus, very yellow when dry, much used for
tliatehmg, etc., by the natives.—ft/iiroHe creeping, sheathed, woody. Oulms erect, stout, three-angled, striated,
1-3 feet high, leafy at the base, bearing at the top a kind of malformed catkin, or succession of catkins, amongst
which grow very long, foliaceous, rigid, why bracteæ. Leaves very numerous, squarrose, concave above, keeled below
towards the long harsh points, margins cutting, with minute teeth. Mmver'mg part of cidm a span long, of confluent
clusters of sessile red-brown spikelets, occupying one side only of the culm, and spirally arranged. Brac-
teal leaves with adnate. open, denticulate, sheathing, decurrent bases, produced into flexuose, rigid, subulate
apices, a foot long. Spikelets sessile, globose, of many imbricated, concave, striated, bluut, obovate, shining scales.
Stamens three ; anthei-s linear, with a long terminal awn. Ovary without bristles ; style trifid, deciduous, not

Chiefly tropical grassy weeds, abundant in Austraha. There is but one New Zealand species (apparently the
B. velata of Port Jackson), forming a slender tufted herb, a span high, with panicled spreading involúcrate umbels
of ovate, acute, pedicellate, compressed spikelets. Leaves slender, long, filiform, subulate, soft- involucral ones
longer than the inflorescence. Soaks all bearing flowers, imbricated on aU sides, ovate, acute, nerved, recurved
scabrid or hispid at the back. B r k lk s 0. Stamm one, StyU bifid, compressed, bulbous below, the bidb covered
with long cilia, that spread downwards over the ovary. Nu t turgid, broadly obovate, compressed, with thickened

The typical species, of which there are three, are natives, one of a high southern latitude, in Fuegia another
0 Port Jackson, and the third of lofty mountains of Tasmania and New Zealand— O, alpina is a densely tufted
rigl , wiry a pme p ant, an inch to a foot high. Leaves linear-setaceous, blunt, grooved above, with broad, quité
smooth shining sheaths.which are sometimes scabrous to the touch. Culms longer or shorter than the leaves, slender,
obtusely three-angled. Spikelets iu few. sessile or pedicelled fascicles from the axil of a bracteal leaf, i inch long,
of four to six glabrous, linear oblong, sliining, concave scales; lower smaller, empty; upper fertile. Bnstles six,
large, flat, feathery, very conspicuous. Stamens tliree. Style bifid. N u t trigonous. (Name from «apt^oç, chaff,
in allusion to the chaffy scales.)
