6. SET ARIA., Beauv. 

 Annual, erect grasses; roots fibrous, stem simple or 

 slightly branched, nodes glabrous; 1. linear, finely acuminate,, 

 flat, ligule a ridge of hairs ; spikelets in contracted, usually 

 cylindric, solitary, terminal panicles, 1-2-fld., not awned, 

 glabrous, articulate on a very short pedicel that bears uni- 

 laterally an involucel of one or more rigid scabrid or barbed 

 bristles (branchlets) ; glumes 4, I— III membranous, 3-5- 

 veined, I half as long as III or shorter, II shorter than IV,. 

 Ill as long as IV, orbicular-oblong, paleate, rarely epaleate, 

 male or neuter, palea hyaline, IV sessile, coriaceous or 

 crustaceous, broadly ovoid, acute, dorsally very convex,, 

 smooth or rugulose, sides incurved; grain oblong, free within 

 the hardened glume and palea. — Sp. about ro; 7 in Fl.

The species of Setaria are variable ; I have described the Ceylon 

 ones according to specimens in Herb. Peraden., which do not represent 

 all the forms which several of them assume in continental India. The 

 character of panicle spiciform or more or less branched is often very 

 fallacious. 



Panicle spiciform, cylindric. 



Bristles of involucel with erect or spreading teeth 1. S. GLAUCA. 



Bristles of involucel with deflexed teeth . . 2. S. verticillata. 

 Panicle more or less lobed or branches elongate. 



Glume IV rugulose all over . . . . 3. S. intermedia. 



Glume IV smooth in the upper third . . . 4. S. gracillima.
