stalks, sometimes straight-sided. Imt tyoieally tumid in the lower 

 part, especially on the side opposite the bud. and sometimes eons- 

 trieted above; more or less staggered: furrow shallow. Nodes rather 

 long, considerably longer on the side to which the hud is attached; 

 leaf-scar usually o])lique; the portion above typically larger in diame- 

 ter than that below : two or three rows of rudimentary roots ; tiu> 

 depressed ring forming the portion below the leaf-scar medium depth 

 and narrow. Buds typically expanded and projecting out from the 

 stalk, but before starting adhering closely to the stalk and typically 

 ovate to oval in outline: margin narrow and conforming to the shape 

 of the bud. ])earded at the point. Foliage abundant, medium green 

 in color. Leaf medium width, length medium to short, growing erect, 

 tapering rather abruptly to a tine point. Leaf-sheath tiatteued at 

 the throat, reddish in color: auricles medium size but sometimes 

 aente-pointed on one side of the stalk ; ligula medium width, with 

 the upper edge rounded to obtuse-pointed in the center. Yestiture 

 of leaf-sheath a few short and tine setae on tlie back, rather closely 

 appressed. Yestiture of throat of sheath medium long and coarse 

 hairs on the auricles, the adjacent edges of the leaf, and sometimes 

 a few l)ehind the ligula. ^tost important distinguishing characters 

 shape and size of tlie internodes and the buds. 



B-6292.— ^Habit erect. Length long. Diameter small. Shape of 

 stalk straight. Color light green to reddish-green, a glaucous riiu' 

 on the node below the leaf-scar. Internodes almost round in cioss- 

 section, usually tumid on the side oj^posite the bud and sliglitly 

 depressed on the l)ud side: furrow, when i)resent, l)ro:ul and shallow. 

 Xodes medium size, longest on the bud side: the depressed ring form- 

 ing the portion below the leaf-scar shallow. Hutis usually having 

 conniienced to expand and standing out from the stalk, the shoot 

 being acute-pointed and extending through the scales; when not 

 having started to develo]) shoots the buds are typically broadly semi- 

 elliptical in outline, with ;i margin of medium width. Foliage me- 

 diinii to ;il)un(laiit, mediiuu green in color. Leaf imrrow ami long, 

 tapering into a long point. Leaf-sheath slightly flattened ;it th" 

 throat: aiiricles lai-ge and obtuse-angular, except occasionally on 

 one .side of the stalk they are semi-acute pointed: ligula medium to 

 long, with the upi)er edge rounded in outline. Vestiture of throat 

 of sheath mediinn coar.se hairs on tlie auricles and adjacent edges 

 ;iii(l surface of the leaf. Most important distinguishing clniractci-s 

 the foi-m of the buds and the long, slender stalk.
