racliis of a simple spike, 1 sessile with 1 perfect flower, the other 

 pedicellate and barren, the spike solitary aud the racliis densely 

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

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

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

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

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

 minute. Styles distinct. Stamens 3. Grain 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. Racemes erect. 



They all differ a little from Manisuris {Rotthcellia), connecting 

 this with Andropogonete. Boissier has proposed Last urns as a 

 genus to include the species, having 3 spikelets instead of 2 at each 

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



Species about 12, mostly perennials spread over tropical and 

 subtropical America and Africa, sparingly in western Asia, and 

 one in tropical Australia.

 Androjjogou candidus Trin. in part. 



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

 or two of the upper ones bearing solitary branches. Sheaths terete, 

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

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

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

 late, much flattened, 7-9 mm. long; first glume lance-elliptical, 

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

 glume 5-6 mm. long, obscurely nerved, third and fourth about 

 equal, 4 mm. long, one 3-nerved, the other 2-nerved. Styles plu- 

 mose, red. Pedicellate spikelets 5 mm. long, borne on pedicels 

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

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

 long; no flower. E. Hackel considers the Brazilian grass, EUonu- 

 rus candidus (Trin.) Hack., to which our form has been referred.
