Graminee.] FLORA OF TASMANIA. 115 
Has. Probably common, but no habitat given, Gunn.—(Fl. Jan.) 
A — handsome Grass, 2—3 feet high, everywhere slightly rough to the touch, similar in many respects to 
A. parviflora.— Culms erect, leafy. Leaves flat, rather narrow, with a membranous ligula. Panicle large, 8-10 
inches long, spreading, very many-flowered. Primary branches numerous, whorled, capillary, as well as the secon- 
dary and long pedicels of the small spikelets scabrid. GZumes equal, ovate, acute, hardly longer than the flower, 
very scabrid, especially along the keel. Palee rather coriaceous, with obscure nerves, awnless; lower truncate; 
upper nearly as long, with two small teeth at the tip, and sometimes a small tuft of hairs at the base.—PLATE

5. Agrostis Billardieri (Br. Prodr. 171); scaberula, foliis latiusculis, panicula laxa, ramis primaris 
cito trichotomis, spiculis majusculis, glumis scaberulis glabrisve flore 4 longioribus, carina seaberula, palea 
inferiore basi sericea 4-nervi, nervis percurrentibus lateralibus aristatis, arista ad medium pales inserta 
glumis 4 ad bis longiore, palea superiore inferiore «equilonga lanceolata cuspidata setula 4 longiore.—

DisrRrs. New South Wales, Victoria, and New Zealand. 
A very elegant Grass, closely allied to the two following, if indeed all three be not varieties of the same spe- 
cies.—Culms tufted, 13 foot high. Leaves 6 inches long, 4-4 inch broad, flat, smooth or rough to the touch. 
Panicle very lax, scabrid ; branches very slender, whorled, trichotomous ; pedicels long, slender. Spikelets larger 
than in the allied species, 4-4 inch long, often purple. Glumes narrow, smooth or scabrid, always scabrid at the 
keel. Lower palea silky at the base, $ as long as the glume, with four nerves that project at the truncate top, the 
lateral of which are produced into short awns. Awn inserted at the middle of the palea, bent, one-half or twice 
as long as the glumes. Upper palea as long as the lower, with two short points, longer than the silky pedicel at its 
back. 
6. Agrostis zemula (Br. Prodr. 172); glaberrima v. scaberrima, foliis latiusculis angustisve, pani- 
cule laxæ ramis primariis elongatis capillaribus trichotomis, glumis (pallidis) glabris carina scaberula flore 
duplo longioribus, palea inferiore sericea brevi late truncata nervis 4 percurrentibus breviter 4-cuspidata, 
arista dorso ad medium palem inserta glumis duplo longiore, nervis lateralibus rarius elongatis, palea 
superiore inferiore breviore obtusa v. bidentata setula plerumque brevissima.—Agrostis Forsteri, Rem. et

Generally a taller plant than D. Billardieri, with many more, much smaller, pale-green spikelets, and more 
silky flowers.—Culms 1-3 feet high. Leaves flat, broad or narrow, quite smooth or scabrous. Panicle 4—8 
inches long, of very numerous whorled, slender branches, that generally do not divide so soon as in the former 
species. Pedicels very slender. Spikelets i-i inch long. Glumes smooth, except along the keel, twice as long as 
the flower, and half as long as the awn. Lower palea very silky all over, truncate, the teeth produced into short 
points. Awn inserted at the middle. Upper palea shorter, blunt or two-toothed. Setula generally very small. — 
This plant is the 4vena filiformis of Forster, in Herb. Hook., and also of Labillardiere, in Herb. Hook. Mr. Brown
