This grass differs from the other Australian species of the genus, principally m habit. 



3. E. annulata (annular), Kunth, Emm. i. 73 ; Benth. Fl. Austr. vii. 463. 

 A smaller and more slender green grass than E. punctata, the leaves usually 

 narrower, glabrous. Spikes slender, 1 to Ifin. long, the main axis of the inflores- 

 cence as well as the rhachis usually glabrous, the pedicels sometimes bearing a 

 few short hairs. Spikelets narrow, tapering at the end, scarcely IJ line long, 

 including the point, which is rather longer than, in E. punctata. Empty glumes 

 much less hairy than iri' that species; 3 or rarely 5 -nerved. Flowering-glume 

 the same.— PaspaZwTO annulatum, Fliigge r Trin. Spec. Gram. t. 133.

3. ISACHNE, R. Br. 

 (Referring to the 2 equal outer glumes.) 

 Spikelets 2-flowere,d, both flowers hermaphrodite or the upper female or the 

 lower male, Small, in loose panicles, the rhachis of the spikelet articulate above 

 the empty glumes, glabrous and not produced above -the flowering ones. Glumes 

 unawned, convex, faintly nerved, 2 outer empty' ones nearly equal ; flowering 

 ones of a firmer consistence, closely sessile or the upper one slightly raised. 

 Palea as long as the glume. Styles distinct. Grain enclosed in the hardened 

 glume and palea, free from them. 



A small tropical genus, common both to th.e New and the Old World. The Queensland 

 species have both a wide range in tropical Asia. 



Leaves lanceolate, Spikelets glabrous or nearly so, nearly 1 line long . . . . 1. I. mistralis. 

 , Leaves ovate, small. Spikelets hairy, about J line long ......... 2. I. viyosotis.. 



1. I. australiS (southern), jB. Br. Prod. 156; Benth. Fl. Austr. vii. 625. 

 Stems, rather slender,, decumbent, creeping and rooting at. the lower godos, 

 ascending to Iffc. or more. Leaves lanceolate, rough, with a minute pubescence. 

 Panicle loose, spreading^ ovoid in circumscription, 1^ to 3in. long, with numerous 

 filiform branches. Spikelets all pedicellate, nearly 1 line long. Outei; glumes 

 quite glabrous. Lower flower usually male, with a glabrous glume, the upper 

 female, shortly stipitate, with the glume usually minutely and slightly pubescent, 

 the rhachis slightly dilated and articulate immediately under the upper glume. —

 Fi. Austr. vii. 625. Slems slender, decumbent and branched at the base, 

 generally short but sometimes extending to l^ft. Leaves- ovate to ovate- 

 lanceolate; small to above lin. long, scabrous, with hairy sheaths and ciliate 

 margins. Panicles ovoid and loose with slender spreading branches as in I. 

 australis but smaller. Spikelets much smaller, rarely above J line long, the 2 

 outer glumes more or less pubescent or hirsute, sometimes" very mu^ so ; 

 flowering glumes glabrous or nearly so, the upper flower female the lower
