Disrris. New South Wales, Victoria, New Zealand, and Norfolk Island. 
A more slender plant than D. crinita, but very closely allied to it, differing in the thin panicle, which is loosely 
branched, and comparatively very few-flowered. The glumes are shorter than in D. erinita, as long as the flower, 
and the twisted awn is not four times longer than the upper palea.—PrATE CLVIII. 4. Fig. 1, spikelet; 2, flower;

3. Dichelachne stipoides (Nob. in Fl. N. Zeal. i. 294. t. 66); caspitosa, glaberrima, polita, 
foliis elongatis strictis setaceo-involutis, panicula erecta contracta pauciflora parce ramosa, glumis levibus 
longe setaceo-acuminatis florem 4 excedentibus, paleis subcoriaceis inferiore sericeo-villosa, arista genicu- 
lata glaberrima flore bis-ter longiore. (Guan, 1490.) 
Has. Abundant, especially near the sea.— (Fl. Nov.) (v. v.) 
DisrarB. Extratropical Australia and New Zealand. 
Also found in New Zealand, growing, as in Tasmania, near the sea.—A handsome, densely tufted, rigid, wiry, 
smooth and polished, yellow Grass, often forming large tussocks, with the habit and appearance of a Stipa.—Culms 
14-3 feet high. Leaves slender, involute, wiry, erect, terete. Panicle contracted, 4-6 inches long, strict, erect, 
few-flowered, and sparingly branched ; branches short, capillary, erect. Glumes ¿44 inch long, white or yellow, 
membranous, thin and shining, lanceolate, with a long slender point. Flower shorter than the glumes, covered 
with soft, silky, spreading hairs. Palee rather coriaceous; lower with two small teeth at the top, one on each 
side the awn, which is curved, about an inch long, and quite glabrous.

A small genus, confined to Australia and Tasmania.—Leaves flat. Culms simple or branched at the base. 
Panicle long, dense, erinite from the number of awns. Spikelets one-flowered, without any rudiment or pedicel of a 
second; flower bearded below, stalked. Glumes nearly equal, keeled, very acuminate, almost awned, shorter than 
the flower. Palee two, the lower with a narrow top ending in five rigid awns, of which four arise from the teeth, 
the fifth, larger, twisted, rises from the back of the palea behind and between the others. (Name evra, five, and 
zwywv, a beard ; in allusion to the five awns.) 
1. Pentapogon Billardieri (Br. Prodr. 173); annua, czespitosa, villosa v. pubescens, rarius glaber- 
rima, culmis erectis sulcatis, foliis involutis, panicula subnutante contracta aristis flexuosis crinita, glumis 
subaristatis ciliatis, palea inferiore scaberula dura aristis brevioribus duplo longiore, arista intermedia geni-
