2. Gl. I and II as in 1, fl. gl. scabrid move or less throughout. 



3. Gl. I and 11 long setaceously lanceolate or lanceolate and long-awned, fl. gls. 

 smooth or scabrid towards the tip. 



4. Gl. I and II as in 3, 9. gls. scabrid more or less throughout. 



2. A. semicostatum, Nees ex Steud. Syn. Oram. 346; tall, sleader, 

 leaves flat, spike elongate, spikelets distant 7-8-fld., gl. I and II linear- 

 lauceolate acuminate smooth or scaberulous strongly 5-7-nerved, fl^. rattier 

 longer erect lanceolate scaberulous above tip entire or 1-2-toothed and 

 narrowed into a straight rarely recurved slender awn twice as long as 

 itself or shorter. Boiss. Fl. Orient, v. 662; Duthie Grass. N.W. Ind. 45. 



Temperate Himahya; from Kashmir to Silckim, alt. 6-11,000 ft. (as low as 

 3000 ft. in the Sutlej valley), Thomson, Sot/le, Jacquemont, &c. — DlSTitiu. Affglian. 

 Turkestan. 



Stems 2-3 ft., tufted, erect, or longer, and up to 8 ft., then weak and inclined. 

 Leaves narrow, rarely ^ in. broad, acuminate, scaberulous or smooth ; sheaths smooth j 

 ligule very short. Spikes 3-8 in., rachis scabrid, slender or rather stout. Spikelets 

 1-2 in. including the awns, green ; internodes of rachilla short ; gls. scabrid as is 

 the callus of the fl. gl. ; empty gls. always large but very variable in size and nerves, 

 ^— f in. long ; flg. gls. erect and appressed, not at all spreading, tip toothed on one 

 or both sides ; awn rarely 1 in. long. — As suggested by Boissier this is very closely 

 allied to A. caninum. In a specimen from Kashmir (^Duthie, No. 12,651| named 

 semicostatum by Hackel, the awns are upwards of an iuch long and reflexed as in 

 longe-aristatum, to which it may be referable. 



Tar. Thomsoni, Hook. f. ; leaves hairy, sheaths villous with reversed hairs. —

3. A. striatum, Wees ex Steud. Syn. Qram. 346 ; tall, robust, leaves 

 flat or involute, spikelets many large imbricating, gls. I and II linear- 

 oblong or oblong-lanceolate as long as (;1. IH acute or obtuse very strongly 

 7- many-nerved, flg. gls. ovate-lanceolate 5-nerved puberulous or glabrous 

 margins usually oiliate, tip notched or entire, awn straight longer or shorter 

 than the gl. Triticum striatum, Steud. I. c. 



Kashmir, alt. 8-12,000 ft., Boyle, Jacquemont, &c. 



Stem 2-4 ft., as thick as a goose's or swan's quill, or more slender. Leaves i— |- in. 

 broad, scaberulous above. Spike 3-8 in., rachis stout, glabrous with ciliolate margins 

 of the hollows or puberulous. Spilcelets J-l in. long, glumes not spreading; I and 

 II subequal, very coriaceous, II j-J in. long, deeply channelled when (ky ; tip 

 sometimes notched or obliquely truncate. — Probably a gigantic form of A. semi- 

 costatum or caninum. 



4. A. Jacquemontii, Hook. /. ; dwarf, leaves filiform flexuous, 

 sheaths hyaline silvery, spikelets 2-5 cuneately obovate, glumes spreading, 

 I and II small lanceolate acuminate, II 3-nerved awned, fl. gls. lanceolate 

 smooth 5-nerved above the middle narrowed into a slender recurved awn 

 many times longer than itself. Bromus tataricus, Jaoquem,. mss.
