 on the same plant with the dark coloured.

 Province, Tkivaites. DISTRIB. N. Africa. 



Very variable in height, 6-24 in., much branched below. Leaves 1-6 by J~ in., 

 glabrous or ciliate ; sheaths 1-1| in.; ligule rounded, scarious. Panicle 2-3 in., 

 peduncle filiform. Spikes erecto-pateut, lowc-st i-f in., upper gradually smaller; 

 rachis trigonous. Spikelets geminate, lower sessile or pedicelled. The pauicled 

 inflorescence is very different from that of P. pedicellare. 



DOUBTFUL SPECIES. 



P. GRIFFITHIANUM, C. Mull, in Sot. Zeit. xxix. (1861) 325. " Foot of Khasia 

 Hills, Griffith." There is no Indian Paspalum that at all resembles the description 

 of this, which, according to its author, is an ally of P. fluitans, Ell., and other 

 American species. There is probably an error as to the habitat and collector. 



2. ERIOCHZ.OA, H. B. & K. 



Annual or perennial grasses. Leaves flat. Spikelets secund on the 

 spiciform branches of a raceme or panicle, base thickened and articulate 

 on the thickened top of the short pedicel. Glumes 3, I and II subequal, 

 membranous; III shorter, apicnlate, hardened in fruit. Lodicules 

 truncate. Stamens 3, anthers linear. Styles free. Grain oblong, free 

 within the hardened glume. Species few, tropical. 



The thickened base of the spikelet alone distinguishes Eriochloa from Paspalum.
