 are glabrous as in typical A. Ischaemiun. For the species see

Habr Awal country, Robecchi. " Grows in small feathery clumps 

 in the plains of British Somaliland. Winn die hot weather comes 

 the leaves fall off, leaving a kind of stubble from 4 to 5 inches 

 long, on which animals feed." — Appleton. 



Distr. (of the species). Abyssinia to the Panjab. 



Col. Appleton also collected several panicles of what seems to 

 be a form of this variety with somewhat smaller, dark purplish 

 spikelets. He says of it : u This grows in tufts with an abundance 

 of green leaves, forming an excellent feed. It requires very 

 little water, grows freely in patches round Little Bohotle, but is 

 frequently met with on the road from Gararo to Upper Sheikh. " 

 The same form was found by Dr. Drake-Brockman in the Golis 

 Range (153). His specimens are very complete. They consist of 

 dense bundles of underground branches dividing, where they 

 emerge from the soil, into short barren, densely leafy shoots, and 

 forming, as Col. Appleton says, " tufts with an abundance of green 

 leaves." The leaves are 1-1-5 cm. long, and the flowering culms 

 springing from the cushion-like tufts are about 25 cm. high. 

 Typical G. Aucheri var. quinqueplumis from Afghanistan and 

 Beluchistan occasionally exhibits a similar mode of growth.
