Throughout India, from the Panjab (ascendinpr the Western Himalaya to 

 8000 ft.) to Bengal and Arracan and southward to Cbylon. — 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 -J-J in., flat, glaucous, setaceously acuminate, 

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

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

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

 length. Spikelets pale green or purplish j gl. I rather thin, obtuse or narrowly 

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

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

 palea 0. — PecUcelled spihelets linear-oblong or -lanceolate j gl. I 5-9-nerved, glabrous, 

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

 less; IT 0.— A variable phiut, nearest perhaps to a Kuntzeanus from wliich 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 ^.^ijafter (Anatherum glabrum, Schult. Mani. ii. iiS) of both whicb there are 

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

 gl I ; A. glaier has few tpikes 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. Mmalayensis ; it is, I think, 

 referable to var. caucasicus.
