lets, fragile. Spihelets i to nearly J in., pale or dark, glabrous to villous ; gl. I from 

 broadly oblong witb a rounded tip to oblong-lanceolate, symmetrical or sligbtly 

 curved or subdimidiate-oblong, upper i or :^ usually herbaceous nerved and with a 

 narrow ciliate wing on one or both sides j II acute or acuminate j IV about J shorter 

 than II, 3-nerved below the insertion of the slender pale awn, which is rarely twice 

 the length of the spikelet ; upper epikelet not awned, pedicel very short. — In Hohen- 

 acker's specimen of var. 'itiangaloricum gl. IV is cleft f way down. In a small form 

 from Salsette (Bombay) Jaequcmont n. 374, the keel of gl. II is notched about the 

 middle, winged and serrulate thence to the tip. 



The following is Hackel's grouping of some of the more distinct forms of this 

 variable plant. It has the advantage of bringing the authorities and synonyms 

 into some order, but does not include all the definable forms, of which I have added 

 two : —
