r;i('l>i.s of a simple spike, 1 sessile with 1 perfect flower, the other 

 pedicellate and barren, the spike solitary and the rachis densely 

 silky-hairy. Onter glume of the barren spikelet usually spread- 

 iiii;-. Fertile spikelet appressed; glumes 4, the outer one firm, 

 largest, erect and often 2-lobed, with a imlsam-bearing line along 

 the nerves, second shorter, thin but rigid and pointed, third and 

 fourth shorter, hyaline, ail without awns; palea none or very 

 minute. Styles distinct. Stamens 3. CJrain enclosed in the 

 outer glumes, but not adherent. Culms tufted, usually erect. 

 Sheaths subtumid; ligule very short, truncate; blades flat or more 

 or less folded. Tkacemes erect. 



They all differ a little from Manisurh {EotfhcelUa). connecting 

 this with AtKh'opofjonece. Boissier has proposed Lasiurus as a 

 genus to include the species, having 3 spikelets instead of 3 at each 

 node of the rachis: but this character is by no means constant. 



Species a])out 12, mostly perennials spread over tropical and 

 subtropical America and Africa, sparingly in western Asia, and 

 one in tropical Australia.

Culms tufted, slender. 50-70 cm. high, containing 3-4 nodes, one 

 f»r two of the upper ones bearing solitary branches. Sheaths terete, 

 loose; blades of the lower leaves verv narrow, often 30 cm. long, 

 the upper 1-4 cm. long, 0.7-1 mm. wide. Spike 0-8 cm. long, 5 

 mm. wide, white with dense silky hairs. Sessile spikelet lanceo- 

 late, much flattened, 7-1) mm. long; first glume lance-eliiptical, 

 densely hairy, obscurely 7-uerved, the lateral nerves heavy, second 

 glume h-{\ mm. long, obscurely nerveil. third and fourth about 

 ('(|ual. 4 mm. long, one 3-nerved, the other 3-nerved. Styles plu-

 rather shorter, the outer glume lanceolate, flattened on the back, 

 hairy, the second acute. 4 mm. long, the third and fourth 3 mm.
