is deeper; two or three rows of rudimentary roots. Buds typically 

 having started to expand on the standing cane and projecting from 

 the stalk ; before starting semi-elliptical to broadly ovate in outline ; 

 margin narrow in the young buds but appearing wide in the older 

 ones, typically semi-elliptical pointed ; lobes inconspicuous ; some- 

 times slightly barbate at the point and barbellate on the sides. Fo- 

 liage medium to scant, medium green in color, dry leaves well shed. 

 Leaf medium to narrow, long, tapering into a long and fine point. 

 Leaf -sheath almost round at throat, slightly glaucous ; auricles medium 

 to large ; ligula medium ^\ddth, with the upper edge either rounded in 

 outline or slightly depressed in the center. Vestiture of leaf-sheath 

 many setae, which are rather long and medium stiff. Vestiture of 

 throat of sheath long and medium course hairs on the auricles and 

 adjacent edges of the leaf, and sometimes a few on the adjacent areas 

 of the face of the leaf. Most important distinguishing characters the 

 form of the buds and the internodes. 



D-117. — Habit erect. Length long. Diameter medium. Shape 

 of the stalk straight. Color light green to yellowish-green. Inter- 

 nodes medium to long, slightly flattened ; typically straight on the 

 side opposite to the one on which the bud occurs, but on the bud 

 side largest at the base and extending up nearly straight from that 

 point ; sometimes slightl.y constricted above the enlargement at the 

 base ; furrow, when present, shallow but rather broad. Nodes large, 

 typically largest on the bud side above the leaf-scar ; often a slightly 

 prominent ring at the line of union with the internode above; leaf- 

 scar projecting prominently from beneath the bud; nidimentary 

 roots many and close together, in three or four rows. Buds typicalh- 

 broadly-ovate to triangular in shape and medium acute-pointed; 

 margin medium to narrow, and uniform in width with the sides 

 of the bud ; lobes inconspicuous or none ; sometimes bearded at the 

 point and barbellate on the sides. Tliese buds sometimes start to 

 expand on the standing stalk, but they ilo not become prominent; 

 the sprout from the bud is plump and medium obtuse pointed. 

 Foliage medium in amount, medium green in color, some of the dry 

 leaves are retained. Leaf medium in Avidth, medium length, tapering 

 into a medium long point. Leaf-sheath slightly flattened laterally 

 at the throat ; auricles medium size but sometimes long-])ointed on 

 one side of the stalk ; ligula short, with the upper edge eitlier rounded 

 or slightly depressed in the center. Vestiture of leaf-sheath a few 

 medium soft setae. Vestiture of throat slieath long hairs on the auri- 

 cles, adjacent edges of tlie leaf, and sometimes liner hairs on tlie 

 adjacent surface of the base of the leaf; also more or less pubescent
