Hab.: Moreton Bay to Darling Dowfls. Common. 



This is a quick-growing excellent pasture grass, and also makes good hay ; it has the 

 advantage over many others of producing good fefed all the year round, for the least rain starts it 

 into growth. 



This grass has been recommended as a substance for the manufacture of tissue and thin 

 wrapper paper. 



2. I>. scmrea (squirrel-tailed), Hook. f. fl. N. Zel. i. 294, Fl. Tasm. ii. Ill, 

 t. 158 A. ; Benth. Fl. Austr. vii. 574. Stems densely tufted, slender, 1 to If 

 rarely 2tt. high, quite glabrous, the nodes usually dark-coloured. Leaves short, 

 ■chiefly at the base of the stem, scabrous-pubescent or glabrous. Panicle narrower 

 and looser than in D. crinita, 3 to Gin. long, the rhachis and filiform branches 

 scabrous. Outer glumes very narrow, about 2|- lines long, the outermost rather 

 shorter than the 2nd. Fruiting glume rather more rigid than in D. crinita and 

 minutely pitted-rugose. Awns 6 to $ lines long, not nearly so crowded as in that

61. ERIACHNE, E. Br. 



(Eeferring to the glumes being hairy.) 



Spikelets 2-flowered, usually not very numerous, in a -loose or dense panicle, 

 the flowers both hermaphrodite and similar, the rhachis of the spikelet articulate 

 above the outer glumes and hairy round the flowering ones. Empty glumes 2. 

 persistent, acute or tapering into a point or short awn, many (usually 9 to 11) 

 nerved. Flowering glumes with fewer nerves, with long spreading hairs on the 

 'iDack or margins, awnless or tapering into a fine straight or curved awn not 

 twisted. Palea very flat, often hairy on the back, with 2 prominent almost 

 marginal nerves. Styles distinct, short. Grain more or less flattened, enclosed 

 in the glume and palea, free from them. 



Besides the Australian species, which are mostly endemic, there are others in South Africa 

 and tropical Asia. 



.AwQS much longer than the glumes. Panicle dense. Spikelets sessile or 

 nearly so.
