A common, tall, harsli Grass, 3-3 feet high.— Oulm stout, silky or downy below, as are the sheaths and knots,
often quite smooth above ; ligula with a tuft of sdky or woolly haii-s. Lower leaves a span long, narrow, involute!
ngid, rough or covered with spreading hairs, sometimes quite smooth; upper often broader. Panicle contracted, a
span long and upwai-ds. Glumes colourless or purplish, rough to the touch but not to the eye, about f incli long,
twice as long as the silky palea. Awns 3 iuches long, densely covered with sdky hairs from the base to about or
above the middle.—A variable Grass, like its congeners, in hairiness and pubescence of the leaves, sheaths, and
culms. The feathered awn always distinguishes it from ail except perhaps S. mollis, Br., of Port Jackson, which I
cannot distinguish from this otherwise. Siebev’s specimen of S. mollis (Agristotheca, t. 60) is the same as Brown’s
S. seniidarbaia. A veiy similar plant, but with shorter awns, inhabits the Swan River Colony.

Veiy similar in habit and general appearance to' S. semibarbata, differiug chiefly in the awn not being
featheiy, Tlie glumes vaiy a good deal in size, as do the awns, from 24-34 inches long. In old specimens
the glumes become truncate and erose at the apex.

A tall slender species, 3 feet high, of which Mr. Gmin has sent copious specimens, but of the flowering culms

smooth, as are the sheaths and involute blades ; ligula very short, quite glabrous, or ciliated. Panicle narrow,
erect, fewer-flowered than in S. flavescens, a span long. Glumes acuminate, not much longer than the flower.

slender, about 18 inches high. Panicle a span long, erect, few-flowered. Primary branches copillaiy, flexuose.

[N o t e .— iS. eleyantissima (Lab. FI. Nov. Holl. i. p. 23. t. 29) is stated by Mr. Brown (Prodi-. 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, capillaiy branches of the wide-
spreading panicle.]

in allusion to the bifid paleæ.)

H a b . Throughout the Island, abundant.—(FL Aug.-Dee.) {v. v )
D is t r ib . Extratropical Australia and New Zealand.
A vciy abundant and vaiiable Grass, quite smooth, or with the lower leaves and sheaths covered with soft
down. Cuhns annual, tufted, 1-3 feet high, stout or slender, leafy at the base and sometimes up to the inflorescence.
Panicle 4-8 inches long, pale yellow-gr,een, shining, contracted, dense and spike-like, rarely thin,
with the branches conspicuous and few-flowered; always covered with the long flexuous arvns. Glums very long,
slender, acuminate, scabrid at the keel, longer than the flowers by one-half or one-tliird. Lower palea long,
scabrous, hard, with a contracted nanow enthe 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 ft'om Dichelachne in the awn not being twisted, from Agrostis in the pedicelled flower, from Muhlenbergia in
the long glumes. I have foUowcd Triiiius and Ruprecht by placing it in the first-named genus, but have retained
the original specific name of crinita, wldch is most appropriate and familiar, and used by Brown, Labillardiere,
Forster, and Linnæus. MM. Trinius and Ruprecht, on the other hand, substitute that of vulgaris for the
Australian specimens, and Forsteriana for the New Zealand ones.
