1. D. sylvatica, Kuntk Revis. Gram. i. 77, Enum. PI. i. 243, 

 Suppl. 188, t. xiv. f . 5 ; tall, leaves long scabrid beneath, panicle contracted 

 at length open, spikelets in., gl. I and II subequal ovate-lanceolate, III 

 rather shorter than I tip shortly lacerate, callus loosely bearded, awn about 

 twice as long as its gl., palea rather shorter than its gl., rachilla shortly 

 bearded. Calaraagrostis sylvatica, DO. Fl. Fr. v. 253 ; Host Gram. Austr.

WESTERN HIMALAYA ; Kunawur, alt. 8000 ft., Thomson- Kashmir, alt. 10-11,000 

 ft., Dutfiie. DISTBIB. Europe, Reg. Caucas. 



Stem 3-5 ft., from a creeping base. Leaves linear, 1-2 ft. by ^- in., finely 

 acuminate ; ligule short. Panicle erect or drooping ; branches short, scabrid. 

 Spikelets green or purplish ; gl. I 1-nerved ; II 3-nerved ; awn of III shortly 

 exserted. I have seen only two Indian specimens, which I think belong to D. 

 sylvatica, Kunth, one from Thomson, with a very large panicle 16 in. long has the 

 callus hairs scanty, about ^ the length of the gl., the other from Duthie has a 

 shorter panicle, a much shorter rachilla, and the callus hairs are more copious and 

 twice as long. I do not venture upon further citations than are given above, the 

 synonymy of both Deyeuxia and Oalamagrostis being in great confusion. 



2. D. elatior, Rook.f. ; very tall, stout, leaves long, panicle 1-2 ft. 

 pyramidal branches long spreading, spikelets in., gl. I and II subequal 

 lanceolate acuminate, III rather snorter than II tip truncate erose, callus 

 laxly bearded, palea rather shorter than its gl., awn exserted, rachilla very 

 short its hairs about half the length of the gl. or longer. Calamagrostis

KHASIA HILLS, alt. 5-5500 ft., Griffith, &c. 



Stem 5-6 ft., as thick as a swan's quill below. Leaves 2-3 ft. by i-f in., coria- 

 ceous, closely nerved, midrib prominent beneath, glabrous or hairy beneath ; sheaths 

 hirsute or glabrescent ; ligule short, scarious. Panicle 4-8 in. broad when expanded ; 

 branches scabrid, lower fascicled. Spikelets subscaberulous ; gl. I and II thin, keels 

 and upper margin of II scabrid ; III membranous, callus hairs sometimes the 

 gl. ; awn subbasal, twice as long as its gl. Grain linear-oblong. Grisebach in re- 

 ducing this to a variety of D. scabrescens, has overlooked the great difference in 

 size and habit, and the different position of the awn which is subbasal. 



3. D. triaristata, Hook. f. ; very slender, leaves narrow, panicle 

 flexuous contracted, rachis and branches capillary, spikelets \ in. few, gl. 

 I and II subequal narrowly lanceolate, III \ shorter than I truncate, two 

 lateral nerves produced into long awns, two intermediate mucros, median 

 awn exserted, palea = \ its gl., hairs of callus = \ gl. III. 



SIKKIM HIMALAYA ; iu woods, Yeumtong, alt. 12,000 ft., J. D. H. 



Stem 1218 in., geniculately ascending from a slender creeping base, weak. 

 Leaves 6-8 in., narrowly linear, finely acuminate, smooth, flaccid ; ligule short.
