Trichopteri/x] xxviii. (UJAMiNEyE. 215 



from among the withered leaf -sheaths of lastseas-on and enveloped 

 at the base by a few leaves reduced to the In-own membranous 

 sheath or with only a small blade ; stem internodes 2 to 3 like the 

 nodes and sheaths gla1)rous ; sheaths cylindrical, dose-litting, 

 much shorter than the internodes; ligule a short dense row of 

 hairs ; blades slender, convolute, rigid and setaceous, erect, the 

 uppermost reaching or overtopping the inflorescence, pubescent 

 on the inner face ; panicle very dense, spikelike, linear, spikelets 

 subsessile or shortly stalked on the very short appressed com- 

 pressed branches, lanceolate-subulate, light l)rown ; gl. I. about 

 half as long as gl. III., lanceolate, subacute, 3-nerved, dorsally 

 flattened, margins incurved with a close line of dark brown warts 

 with spreading white bristly hairs; gl. II. linear-lanceolate, 

 acuminate, blunt, 3-nerved, the involute margin minutely scabridu- 

 lously hairy from below the middle to below the tip; gl. III. 

 exceeding gl. II., linear below, tapering above into an acuminate 

 iiwn ; 3-nerved ; pedicel of fertile flower slender, bearing short 

 basal tufts of hair like the callus, fertile gl. coriaceous, puberulous, 

 convolute, inconspicuously 7-nerved with minutely bilobed apex 

 between which springs the long awn ; pale linear-tapering, nerves 

 strong, approximate. 



Culms 11 to nearly 2 ft. long, sheathed for about 2 in. at the 

 base, internodes '} to ] line in diameter ; cauline sheaths 2 to 3 in. 

 long, leaf -blades 3 to 5 in., }^ to 1 line in thickness in their natural 

 convolute condition. Panicle barley-like, 1^ to 3 in. long not 

 including the awns ; fully developed spikelets '^ in. long ; gl. I. 

 4 to 4}, lines long, gl. II. 7^ lines or slightly less, gl. III. 8^ to 9 

 lines, pale 4 lines, narrow, flattened, with a bifid apex ; pedicel of 

 fertile flower slender, l.V line long, exceeding the truncate callus, 

 gl. 3 lines long including callus, column of awn pale brown, 

 twisted, about 1 in. long, subula greenish 1| to l?j in. long, pale 

 narrow, 2f line. The stamens have dropped, but there appear to 

 have been 2 in the $ flower. 



A distinct species near T. hordeiformis Stapf, but differs in its 

 perennial habit, narrow setaceous leaves, glabrous nodes, shorter 

 inflorescence and relative lengths of the glumes.

('ulms slenderer than in the type with short narrow -linear 

 tapering involute leaves, and basal sheaths glabrous like the 

 upper; spikelets smaller, 10 to 13 lines long, and gl. I. less robu.st 

 and generally more acute. Leaves 5 to 1 !", in. long, 2 lines or less 

 in breadth.
