EXCLUDED GENUS. 



PRIONANTHIUM, Desv. Opusc. 65 t. 4, is a S. African grass, erroneonsly described 

 as Indian. It was subsequently published by Nees as Prionachne Ecklonii. 



Tribe I. PANICE^E. (See p. 2.) 

 1. PASPALUBX, Linn. 



Annual or perennial grasses. .Spikelets 1-fld., secund in simple spikes 

 or spikelike branches of a simple panicle or raceme, articulate on the 

 pedicel but not thickened and callous at the base, never awned. Glumes 3 

 (homologous of II III and IV in Panicum), with rarely a very minute 

 lowest fourth (I of Panicum) ; I and II subequal, membranous, .both some- 

 times very small or I (at the back of the fl gl.) absent ; II. epaleate ; III 

 more coriaceous, paleate, bisexual. Stamens 3. Styles 2, free. Grain free 

 within the hardened glume. Species perhaps about 160, natives of all 

 warm regions. 



As above defined, Paspalum includes the Digitaria section of Panicum, which 

 appears to me to be artificially placed in the latter genus, because of the occasional 

 presence of a very minute scale-like glume at the base of what is the 3rd gl. of 

 Panicum (that opposite the fig.). This minute glume which is present or absent 

 even in the same species, is nerveless and never embraces that above it, as the lowest 

 gl. always does in Panicum proper. One Indian species alone of Panicum (P. 

 subeglume) has only 3 glumes, buc its decompound panicle and the form of its spikelets 

 and its affinities are with Panicum.
