282 TR1ANDRM DIGYNIA. Panicum. 



P. conglomeratum. Linn. sp. pi. ed. Willd. i. 341 . does not 

 agree with our plant in having cylindrical spikes with flowers 

 equally disposed on all sides. This is a very small species, 

 a native of Coromandel. 



2. P. barbatum. R. 



Culms from three to five feet high; very ramous at top. 

 Leaves lanceolate. Spikes simple, cylindric. Involucrets 

 simple, and bearded, surrounding on every side a single 

 flower ; seed smooth. 



This species sprung' up in beds, in the Botanic garden 

 where earth had been thrown that came from Sumatra, or 

 Amboyna. Compare with P. polysiachyon. Linn. sp. pi. ed. 

 Willd. i. 335. 



Root annual in Bengal. Culms erect, about five feet high, 

 simple, till near the top, there very ramous. Leaves lanceo- 

 late, often a foot and a half long, hispid on the margins, other- 

 wise smooth ; the sheaths about half the length of the joints, 

 with a few single hairs at the mouth. Spikes terminal, and 

 solitary (though from the numerous ramification of the top of 

 the culms the whole may be called a large leafy panicle) sub- 

 cylindric, about three or four inches long. Invoh/crets of 

 two sorts, the longest about twice the length of the flowers 

 with their lower half bearded, hence the specific name, which 

 for the same reason is also applicable to my Pa?iicitm hol- 

 coides,) the innermost one is in this species about double the 

 length of the other five, six, or seven; all are of a reddish 

 brown colour from the bearded part to the point. The other 

 sort of involucrets are simple and about the length of the 

 flowers. The two sorts surround on all sides a single flower. 

 Calyx one- flowered, exterior valve very minute. Seeds smooth, 

 slender and pointed. 



Ohs. It ditfers from my P. holcoides in the culms being' 

 very ramous at the top only, and in the leaves being lanceo- 

 late ; from polysiachyon it differs, I think, in having two
