very short, spreading, whorled or fascicled, one- to three-flowered. Glumes purple, } inch long, one-half longer than 
the flower. Palea silky. Awn 3 inches long, very slender, glabrous or faintly downy.—PraTE CLVII. B. Fig. 1, 
spikelet; 2, flower; 3, ovary, squamule, and stamens :—all magnified. 
[NorE.—S. elegantissima (Lab. Fl. Nov. Holl. i. p. 23. t. 29) is stated by Mr. Brown (Prodr. p. 175), on 
the authority of the late Mr. Lambert's herbarium, to be a native of Tasmania. It is a native of S. W. Australia 
and Swan River, and may be recognized at once by the long, beautifully ciliated, capillary branches of the wide- 
spreading panicle.]

Spicule 1-flore ; floris stipite brevi barbato. Glumæ 2, membranacem, acuminate, florem «equantes 
v. superantes. Palee 2, inferior scabra v. sericeo-pilosa, bifida, inter lobos aristata; arista simplici, 
subtorta, basi inarticulata; superior brevior, linearis, 2-dentata.  Sguamule 3, subfaleate ; interior con- 
formis, tenerior.—Folia convoluta ; panicula coarctata. : 
Rigid, wiry Grasses, with subulate or convolute leaves, and narrow, rather dense panicles of shining flowers ; 
natives of Australia, Norfolk Island, and New Zealand.—Glumes two, membranous, sharp, as long as or longer than 
the solitary flower, which has a short bearded stalk. Palee two, lower membranous or coriaceous, scabrid or silky, 
bifid, with a twisted awn from between the lobes, which is not jointed on to the palea; upper shorter, linear, 
two-toothed at the tip. Scales three, curved. Seed very narrow. (Name from dynos, cloven-footed, and og, chaff ; 
in allusion to the bifid palez.)

Has. Throughout the Island, abundant.—(Fl. Aug.-Dec.) (v. v.) 
Disrris. Extratropical Australia and New Zealand. 
A very abundant and variable Grass, quite smooth, or with the lower leaves and sheaths covered with soft 
down. Culms annual, tufted, 1-3 feet high, stout or slender, leafy at the base and sometimes up to the in- 
florescence. Panicle 4-8 inches long, pale yellow-green, shining, contracted, dense and spike-like, rarely thin, 
with the branches conspicuous and few-flowered ; always covered with the long flexuous awns. Glumes very long, 
slender, acuminate, scabrid at the keel, longer than the flowers by one-half or one-third. Lower palea long, 
scabrous, hard, with a contracted narrow entire or bifid point, and a dorsal awn, which is flexuous and not twisted, 
inserted above the middle. Upper palea shorter, narrow, membranous, bifid at the top.—This curious plant 
differs from Dichelachne in the awn not being twisted, from Agrostis in the pedicelled flower, from Muhlenbergia in 
the long glumes. I have followed Trinius and Ruprecht by placing it in the first-named genus, but have retained 
the original specific name of crinita, which is most appropriate and familiar, and used by Brown, Labillardiêre, 
Forster, and Linneus. MM. Trinius and Ruprecht, on the other hand, substitute that of vulgaris for the 
Australian specimens, and Forsteriana for the New Zealand ones.
