A very small, Ekoeharie-XNe. plant. Book tufted, creeping. Culm erect, setaceous, leafy below, 1-2 inches
high, slender. Leaves shorter than the culms, setaceous, with ehesnut-hrown sheaths, Spikekt cylindi-ical, ovate,
solitary, shming, brown, 2 lines long, lateral or terminal when the lower scale forms the apex of the culm, and is
setaceous. Scaks rolled round one another on all sides, blunt, two- or three-flowered. Stamens and Styles three.
Nut pale brown, trigonous, turgid, scabrous or glabrous, surrounded at the base with a dense brush of short inarti-
cGate bristles, besides tie scabrous scales,—Allied to 0. nitens, but tbe spikelets are nearly sohtary ; scales more
convolute and blunter, and the hypogynous bristles quite different.—P late LXII. B. Fig, 1, spikelet ; 2, the

A small, slender plant, 2 inches to a span high. Culms leafy below, with bright, brown, varnished sheaths,
triangular or rounded, furrowed, longer than the setaceous grooved leaves. Spikelets lg -2 hnes long, broad, sessile,
crowded, lateral or rarely terminal. Scales few, very broad, blunt, truncate or two-lobed. Seta very numerous,

A small genus of densely tufted, mossy, rigid, subulate-leaved plants, forming convex patches on the mountains
of Tasmania, Fuegia, and New Zealand. The 0. pectinatus was discovered in Auckland Island, forming great
convex green lumps in the peaty soil.-—Ste'ms densely tufted, 1-3 inches long. Leaves rigid, subulate, distichous
and equitant, with hard striated sheaths, curved outwards and upwards, l | - 3 i inches long. Flowers minute, solitary,
on very short terminal peduncles, which are elongated (1 inch) and rigid in fruit. Scales two or three, enclosing one
fiower, with six ovate acuminate scales in two series, forming a perianth, which is persistent after the nut falls
away. Stamens three; filaments long. Style one, trifid, bulbous below. Nut obovate. (Name from opos, a
mountain, and fSoiXoç, a ball.)

Generally large sedgy or rush-like plants, found in many parts of the world, with simple or decompound, spicate,
fascicled, or panicled inflorescence, and round, triquetrous, or flat stems. Some of the New Zealand species are
anomalous, and may be referred to Lampocarya or Lepidosperma.— Spikes of many scales, imbricated all round ;
upper three or four with triandrous flowers. Bristles or scales 0, or very obscure. Nut with a deciduous style,
sharp, not thickened at the top. Seed not transversely wrinkled. (Name from «A-aSos, a branch; from the many
branched spikes.)
