involucrali rarius auctis, squamis nitidis late ovato-rotundatis obtusis, setis hypogynis plumosis, stylo 
3-fido, antheris mucronatis, nuce late trigono nitido.—Br. Prodr. 
Has. Northern Island. Sandy flats on the Hast Coast, Colenso. 
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 14-2 lines long, broad, sessile, 
crowded, lateral or rarely terminal. Scales few, very broad, blunt, truncate or two-lobed. Sete very numerous, 
small, unequal, or six and finely divided into many hairs. Nut very broad, three-angled, polished. Styles three. — 
Very closely allied to a Valdivian (South America) species, which only differs in the longer bristles being fimbriated 
at the base. C. nitens is a native of South Australia and Tasmania, 
Gen. IX. OREOBOLUS, Zr. 
Flos solitarius, pedunculatus. Squame 2-8, spathacem. Perianthium (squamule hypogynee) 6-par- 
titum, persistens. Stamina 3. Stylus 3-fidus, basi bulbosus. Nua 3-gona, crustacea, obovata; puta- 
mine apice incrassato. 
A small genus of densely tufted, mossy, rigid, subulate-leaved plants, forming convex patches on the moun- 
tains of Tasmania, Fuegia, and New Zealand. The 0. pectinabus was discovered in Auckland Island, forming great 
convex green lumps in the peaty soil.—Stems densely tufted, 1-3 inches long. Leaves rigid, subulate, distichous 
and equitant, with hard striated sheaths, curved outwards and upwards, 13—3% 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 
flower, 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 BwAos, a ball.) ;

Spieule l-3-form. Sguame@ undique imbricate, plereque vacuæ. Seta hypogyne 0. Stylus deciduus, 
cum ovario articulatus. Nux styli basi equali mucronata; nucleo non transversim rugoso. 
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, iriquetrous, 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 kkados, a branch; from the many 
branched spikes.)
