Ti'inius' plant is from San Domingo in the West Indies, and if it w«re not on the authority oj 

 Muhro.I should have great hesitation in uniting with it this one from. Central Australia, but I 

 can -fintl nothing to separate the specimens from these two distant regions,: although; Trinius's 

 figure represents a much looser aud less copious infloresoenee than that of the Australian 

 plant. — Benth.

 nodes often much thickened. Leav.es flat,- narrow, tapering into fine points. 

 Panicle terminal, loose and slender, consisting of few distant spreading simple or 

 scarcely divided branches,. the rhachis almost filiform. Spikelats few and distant

 li'airs, rarely quite glabrous. Leaves narrow, with short shpaths, the ligulavery 

 short or scarcely prominent, ciliate. Panicles in the axils of the numerous floral 

 leaves, often scarcely exceeding them, reduced to very few unequal spreading 

 capillary branches, each bearing 1 to 3 spikelets, all pedicellate glabrous, acute,

 them by a stipes or prolongation of the rhachis bordered under the spikelet by a 

 broad short hyaline membrane.
