110 FLORA OF TASMANIA. | Graminee. 
1. Stipa semibarbata (Br. Prodr. 174); culmis basi nodis vaginisque sericeis pubescentibusve, 
ligula ciliata, foliis infimis setaceis scabris pilosis glabratisve caulinis sepius latioribus glabratis, panicula 
subcontracta, glumis flore 4 v. bis longioribus, palea inferiore sericea, arista longissima e basi ad v. ultra 
medium plumosa.—Kunth, En. i. 183. (Gunn, 1480, 1452.) 
Has. Abundant in dry soil throughout the Island.—(Fl. Nov.) (v. v.) 
DisrRIB. Extratropical Australia. 
A common, tall, harsh Grass, 2-3 feet high.— Culms stout, silky or downy below, as are the sheaths and knots, 
often quite smooth above; ligula with a tuft of silky or woolly hairs. Lower leaves a span long, narrow, involute, 
rigid, rough or covered with spreading hairs, sometimes quite smooth; upper often broader. Panicle contracted, a 
span long and upwards. Glumes colourless or purplish, rough to the touch but not to the eye, about 2 inch long, 
twice as long as the silky palea. ` Jeng 3 inches long, densely covered with silky 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 all except perhaps 8. mollis, Br., of Port Jackson, which I 
cannot distinguish from this otherwise. Sieber’s specimen of S. mollis (Agristotheca, t. 60) is the same as Brown's 
S. semibarbata. A very similar plant, but with shorter awns, inhabits the Swan River Colony. 
2. Stipa pubescens (Br. Prodr. 174); glaberrima, v. culmis basi nodis vaginisgue pubescentibus, 
foliis infimis setaceis patentim pilosis scaberulis glabrisve, ligulis nudis villosisve, panicula contracta, glumis 
flore $ v. bis longioribus, palea inferiore sericea, arista longissima nuda v. infra medium pubescente.—Kunth, 
En. i. 183. S. pubinodis, Trin. et Rupr. Stip. 50. (Gunn, 588, 996, 1453.) 
Has. Common in dry soils.—(Fl. Nov.) (v. v.) 
DIsTRIB. Extratropical Australia. 
Very similar in habit and general appearance to S. semibarbata, differing chiefly in the awn not being 
feathery. The glumes vary 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. 
3. Stipa flavescens (Lab. Fl. Nov. Holl. i. p. 24. t. 30) ; glaberrima, v. culmis ad nodos subsericeis, 
foliis strictis involutis, ligula truncata brevissima nuda v. ciliata, panicula rara contracta erecta, glumis 
flore paulo longioribus, palea inferiore sericea, arista breviuscula nuda glaberrima v. puberula.— Br. Prodr. 
175. Kunth, En.i. 183. S. leviculmus, Nees, Plant. Preiss. ii. 99. (Gunn, 996, in part.) 
Has. Tasmania, probably common, Gunn, etc.— (Fl. Dec.) 
Disrris. Southern and temperate Australia. 
A tall slender species, 3 feet high, of which Mr. Gunn has sent copious specimens, but of the flowering culms 
only, without root and lower leaves, and with no precise habitat attached.—Culms above and upper leaves per- 
fectly smooth, as are the sheaths and involute blades; ligula very short, quite glabrous, or ciliated. Panicle nar- 
row, erect, fewer-flowered than in S./favescens, a span long. Glumes acuminate, not much longer than the flower. 
Awn quite smooth, or downy, 2 inches long. 
4. Stipa setacea (Br. Prodr. 174); gracilis, foliis setaceis, vaginis brevibus membranaceis sericeis 
vaginis nodisque glabris pubescentibusve, panicula stricta rariflora effusa, ramis primariis brevibus subverti- 
cillatis flexuosis, arista geniculata elongata nuda.—Kunth, En. i. 183. (Gunn, 1487.) (Tas. CLVII. B.) 
Has. Tasmania, Brown; Launceston, Gunn. 
Distris. Extratropical Australia. 
A very pretty, slender species.— Leaves short, 3-5 inches, setaceous, smooth, glabrous or more or less downy, 
with a silky, short, membranous ligula (I do not find the ligula to be elongated as described by Brown). Culms 
slender, about 18 inches high. Panicle a span long, erect, few-flowered. Primary branches capillary, flexuose,
