Throughout INDIA, from the Panjab (ascending the Western Himalaya to 

 8000 ft.) to Bengal and Arracan and southward to CEYLON. DISTEIB. Westward 

 to the Caucasus, China, Malaya, and the Pacific. Trop. Africa. 



Perennial. Stem 3-5 ft., stout or slender, slightly flattened on one side ; nodes 

 glabrous or hairy. Leaves 6-18 by i-g i 11 -, flat, glaucous, setaceously acuminate, 

 ciliate towards the base ; sheath hairy at the top ; ligule very short, truncate. Panicle 

 very variable in form and density, pyramidal thyrsiform or subcorymbose, rachis 

 and branches glabrous the latter usually in opposite pairs ; spikes variable iu 

 length. Spikelets pale green or purplish; gl. I rather thin, obtuse or uarrowly 

 truucate, 4-7-nerved ; II oblong or lanceolate, 3-nerved, keel smooth, margins 

 glabrous; III = I, oblong, glabrous, nerveless; IV a slender awn, 1-1^ in. long, 

 palea 0. Pedicelled spikelets linear-oblong or -lanceolate ; gl. I 5-9-nerved, glabrous, 

 keels ciliolate ; II lanceolate, 3-nerved, ciliate; III shorter, oblong, glabrous, nerve- 

 less; IV 0. A variable plant, nearest perhaps to a Kuntzeanus from which the 

 paniculate inflorescence and smaller spikelets distinguish it. In some specimens the 

 spikes are reduced to a few, and then the paniculate character disappears. 



The following are Hackel's varieties of the Indian plant, which a larger series 

 of specimens than he had access to tends to invalidate. Roxburgh's A. punctatus 

 and A. glaber (Anatherum glabrum, Scliult. Mant. ii. 446) of both which there are 

 good original drawings, do not fall under any of Hackel's vars. Both have pitted 

 gl I ; A. glaber has few s- pikes on the branches of the panicle, A. punctatus has many 

 long quite simple spikes on a rather short rachis. Hackel has given a plant of 

 Duthie's from Simla, 7-8000 ft., the mss. name of var. himalayensis ; it is, I think> 

 referable to var. caucasicus. 



Var. genuinus; panicle 4-5 in. subsimple, branches with one or few spikes, gl. I 

 not pitted appressedly hairy below, keels rigidly ciliolate. A. Vachelii, Nees in

Var. Hoenkii; panicle 5-6 in. compound, branches with 4-8 spikes, sessile spike- 

 lets g- in., gl. I rarely pitted slightly depressed along the middle line, keels rigidly 

 ciliolate. A. Hsenkii, Presi Eel. Hcenk. i. 340. A. Vachelii, /3, Hook. Sf Arn. I.e.
