Shape of stalk more or less curved. Color green when young, yel- 

 lowish-green when mature ; the surface is smooth and sometimes 

 glossy on the young stalks but when old it often contains fine cracks ; 

 usually glaucous on the lower portion of the node. Internodes me- 

 dium length ; typically variable in shape, but tumid on the side op- 

 posite the bud and more or less staggered ; furrow broad and shallow, 

 deepest underneath the bud. Nodes medium length ; the depressed 

 ring forming the portion below the leaf-scar medium width and depth, 

 deepest immediately below the bud ; rudimentary roots far apart, 

 white, in two to four rows. Buds medium size, typically ovate to 

 triangular in outline, rather flat when young: margin usually nar- 

 row and conforming to the shape of the ])ud : sometimes pubescent 

 at the base. Foliage al)undant, medium green in color. Leaf of 

 medium length and width, tapering into n medium long point. Leaf- 

 sheath flattened laterally at the throat ; auricles medium to large, 

 often a little more pointed on one side of the stalk than the other; 

 ligula medium to long, with the upper edge rounded to obtuse-pointed 

 in the center. Vestiture of leaf-sheath rather fine setae. Vestiture 

 of throat of sheath medium soft hairs on the auricles and edges of 

 the base of the leaf, and sometimes a few in adjacent area behind 

 the ligula. Most important distinguishing characters color and shape 

 of the buds and the internodes. 



B-7245. — Habit erect. Length medium. Diameter medium to 

 large. Shape of stalk straight. Color green to yellowish-green, some 

 of the upper internodes slightly reddened ; the lower portion of the 

 node glaucous. Internodes medium to long, nearly round in cross- 

 section, almost straight-sided, but the shorter internodes are tumid 

 and the longer ones typically slightly constricted in the lower half 

 on the bud side, or all around, making the upper half the largest in 

 circumference; furrow broad but usually shallow. Nodes medium 

 to large, the portion above the leaf-scar short on the side opposite 

 the bud; typically smaller in diameter above than below; the upper 

 portion increasing in size from below upward, and forming a promin- 

 ant ring at the upper extremity of the node; the leaf-scar and the 

 depressed ring forming the portion below it oblique ; two to three 

 rows of rudimentary roots, which are conspicuous. Buds varying in 

 size, generally adhering closely to the stalk, usually al)out as broad 

 as long; typically ovate to broadly ovate in outline, with the point 

 rounded and the margin medium to narrow ; sometimes bearded at 

 the apex. Foliage abundant, medium green in color. Leaf medium 

 to wide but variable, medium length, tapering into a medium to long 

 point. Leaf -sheath distinctly flattened laterally at the throat ; auri-
