being directed forward or upward, not downward ; and we can 

 hardly conceive this character to be variable. The neuters/ore* 

 is more frequently wanting in this species. The minute rough- 

 ness of the corolla is like the last. Sometimes the spike, though 

 usually green, has a purple tinge.

Annual. July. 



Root fibrous. Stems several, often 2 feet high, stout, leafy, smooth, 

 with some tufts of radical leaves, and a few short, more spread- 

 ing, stems, at their base. Leaves harsh, pointed, neither warty 

 nor hairy. There are no stipulas of any kind, one represented in 

 Engl. Bot. being an error. Sheatlis compressed, striated, smooth. 

 Panicle erect, rigid, unilateral, with angular rough-edged stalks -, 

 its lower branches rather distant, and zigzag ; upper crowded $ 

 all with tufts of fine smooth bristles, originating in tubercles, at 

 their base ; which bristles seem not essentially different from 

 those of Richard's Pennisetum, and greatly invalidate the sup- 

 posed character of that genus, of which our two foregoing species 

 are examples. The larger valve of the calyx is ovate, concave, 

 ribbed, bristly, pointed, or slightly awned ; smaller cup-shaped, 

 embracing the whole base of the flower. Cor. of the perfect 

 floret 2 ovate awnless valves, very smooth, and even, finally 

 horny coating the seed j the larger concave, obscurely ribbed'; 

 the inner smaller, flattish : that of the neuter floret of 2 very 

 dissimilar valves j the outermost resembling the outer valve of 

 the calyx, to which it has heretofore been supposed to belong, 

 concave, ribbed, bristly, inflexed at the edges, and terminating 

 in a rough, straight awn, generally short, as in Engl. Bot. } but 

 sometimes very long as in Leers, and Morison's/ 16 ; the in- 

 nermost rather smaller, thinner, flat, notched at the tip, see
