298 TR1ANDRIA DIGYNJA. Panicum. 



valved. Seed ovale, longitudinally streaked, and transverse- 

 ly rugose. 



This is also a native of pasture ground, but chiefly that 

 which is shaded. It is exceedingly like the last described 

 species. 



Culms creeping-, &c. as in the last. Leaves also the same. 

 Spikes, the same as in P. grossarium. Spikelets or rather ra- 

 cemes, the lower one or two sometimes branchy in luxuriant 

 plants. Rachis, common, striated ; partial three-sided, and 

 downy. Flowers, the inferior ones in pairs, upon a short, 

 common pedicel ; besides, having their partial pedicels, one 

 of which is nearly as long as its flowers; above they are often 

 single, and somewhat remote ; hairs surround the insertion of 

 all. Calyx hairy. Corol, the neuter valve is here present. 

 Seed ovate, a little pointed, rugose, like that of the last species. 



Obs. The chief character consists in the lower flowers of 

 the racemes being paired on a common peduncle, with pedi- 

 cels of very unequal lengths and hairy involucres. 



28. P. cuspidatum. R. 



Creeping near the base, wholly smooth. Leaves linear, 

 without ligula. Spikes compound, secund ; spikelets adpress- 

 ed, secund. Flowers from one to three, equally sub sessile, 

 all hermaphrodite ; valves of the calyx three-nerved, and cus- 

 pidate. Seed cuspidate. 



A native of Bengal. Found in a rich moist soil, in flower 

 and seed in April. 



Culms, numerous in luxuriant tufts, creeping near the ori- 

 ginal root, then ascending to about two feet in height, ramous, 

 smooth. Leaves ensiform, smooth, with coloured margins. 

 Sheaths shorter than the joints, smooth, and completely des- 

 titute of ligula. Spikes compound, secund, slightly recur- 

 vate, with the secund spikelets on the convex side pressing 

 on the common, three-sided, hispid rachis ; often of a dull 

 purple colour. Flowers, from one to three together, and 

 equally sub sessile, Cah/x, all the glumes three-nerved, and
