slightly depressed in the center. Vestiture of leaf-sheath none. Ves- 

 titnre of throat of sheath medium soft hairs on and adjacent to the 

 auricles; also sometimes slightly pubescent on the face of the base 

 of the leaf. Most important distinguishing characters the form of 

 the internodes and the buds. 



B-7169. — Habit erect. Length medium. Diameter medium. 

 Shape of the stalk usually straight. Color yellowish-green to red- 

 dish-green, having a somewhat glossy surface and sometimes with 

 a -few fine cracks in the epidermis; the lower portion of the node 

 sometimes glaucous. Internodes medium length, nearly round in 

 cross-section ; typically almost straight-sided but a little tumid on 

 the side opposite the bud; the lower portion often slightly the largest 

 and becoming smaller until the node is reached; furrow none or 

 very shallow. Nodes medium size ; almost uniform in length around 

 the stalk, but the portion above the leaf-scar sometimes longer, and 

 that below a little shorter on the bud side, the leaf-scar then being 

 set at an angle ; three or four rows of rudimentary roots, which show 

 as white points. Buds regular in shape; typically ovate to acute in 

 outline and acute-pointed; usually flat against the stalk but occa- 

 sionally slightly prominent ; margin narrow, with the edges straight 

 or conforming to the shape of the bud ; lobes small ; scales of fine 

 texture. Foliage abundant, medium green in color. Leaf medium 

 to narrow, medium length, sub-erect, tapering into a medium long 

 point. Leaf -sheath flattened laterally at the throat ; auricles medium 

 to small ; ligula medium length, with the upper edge rounded to sub- 

 elliptical. Vestiture of leaf-sheath a band of setae on the back, 

 rather long and medium stiff. Vestiture of throat of sheath medium 

 fine hairs on the auricles, adjacent edges and face of the leaf, and 

 sometimes a few behind the ligula. ]\Iost important distinguishing 

 characters color and glossy appearance, and the form of the inter- 

 nodes and the buds. 



B-3405. — Habit erect to inclining. Length medium to long. 

 Diameter medium. Shape of stalk nearly straight. Color reddish- 

 green, being reddest in the upper internodes and where exposed to 

 the sun ; often glaucous on lower portion of the node. Liternodes 

 medium length, slightly flattened, typically slightly tumid on the 

 side opposite the one which bears the bud, and sometimes a little sub- 

 conical ; often slightly staggered ; furrow shallow but usually broad. 

 Nodes medium size ; leaf-scar often oblique and usually projecting 

 prominently from beneath the bud; the portion above the leaf-scar 

 rather long; the depressed ring forming the portion below medium 

 Avidth and shallow, excepting immediately below the bud where it
