 lappaceus, Tausch in Flora XX. (1837) 57. The Panjab, Upper Gangetic Plain, and 

 Deccan Peninsula, Arabia, Africa, Madeira. A nearer approach to Cenchrus than 

 P. cenchroides, but at once distinguishable from that genus by the filiform tips of 

 the bristles of the involucel. It occurs here and there in the sanfe areas as P. 

 cenchroides, and passes into it.

Quite glabrous. Stems tall, slender, erect, or short prostrate stout and much 

 branched, with geniculate leafy branches. Leaves 1-8 in., rigid, narrow with 

 filiform tips, scaberulous ; sheath inflated ; ligule of very fine hairs. Spikes on 

 long exserted or short included peduncles, 2-4 in. long, 1^ in. diam. across the 

 bristles, very pale ; rachis slender, geniculately flexuous, compressed, quite smooth ; 

 involucels subsessile ; bristles 1 in. flexuous, dilated and ciliate below. Spikelets % in. ; 

 gl. I ; II = III both ovate-lanceolate, cuspidately acuminate, 5-nerved ; IV like 

 III, but rather longer, 5-nerved ; palea like the gl., 2-nerved. Anthers linear. Grain 

 broadly orbicular-oblong, cuspidate, flattened, 



DOUBTFUL SPECIES., 



P. NEPALENSE, Spreng. Syst. i. 303 (to which Grisebach refers lanatum, Kl.) 

 differs according to the description from lanatum in the coloured sefrse, which are 

 not described as branched, and in the habitat, Nepal, which is far to the east of the 

 range of lanatum. Sprengel's specimen is in all probability from Wallich, who 

 alone had distributed plauts from Nepal at that time. 



15. CENCHRUS, Linn. 



Characters of Pennisetum, but involucels composed of subulate hard 

 spines without filiform tips, connate below into a short coriaceous cup, 

 -which is surrounded by erect or squarrose bristles. Species few, tropical 

 and subtropical.
