region, from Spain to Egypt and Arabia, is a slight variety with a stouter dense 

 panicle, which Dr. Stapf and I have independently sought in vain to distinguish by 

 any other character, and this is of the slightest.

Perennial ; stems 12-18 in., densely tufted. Leaves 2-5 by -j^-J in., narrowed 

 from the cordate base to the finely acuminate tip, margins smooth, somewhat haiiy 

 towards the base ; ligule a ridge of minute hairs. Panicle 3—5 in., interrupted, very 

 pale yellowish. Spikelets very shortly pedioelled ; gls. all 1-nerved j I and II 

 hyaline, puncticulate ; I rather shorter and narrower than II. — Of the synonymy 

 cited above that of V. littoralis |3, and the two sp. of AgrosHs are taken from J. 

 Gay's mss. on a Senegal specimen in Herb. Kew. Of V. scairifolia I know nothing, 

 nor where Edgeworth gets the name (which is not in the " Kew Index," but from 

 his citing Stock's number (667) as the same plant, there is no doubt that S, 

 glaucifolius is that meant. Edgeworth (I.e. 182) mentions this amongst other 

 plants of which the seeds are swept up for food by the poorer classes of the desert.
