C'les medium to large, those on one side of the stalk sometimes acute- 

 pointed, and on the young sheaths, overlapped by the others; ligula 

 medium to short, with the upper edge sub-elliptical, to obtuse-pointed 

 in the center. Vestiture of leaf-sheath very long, sharp and promin- 

 ent setae. Vestiture of throat of sheath medium soft hairs on the 

 auricles, edges of the leaf, and a few back of the ligula. Most im- 

 portant distinguishing characters the shape and size of the internodes 

 and the buds. 



B-1809. — Habit erect. Length long. Diameter large. Shape of 

 stalk straight. Color medium green when young, but becoming yel- 

 lowish-green with age ; a glaucous ring on the node below the leaf- 

 scar, which becomes dark with the aging of the stalk. Internodes 

 medium to long, flattened ; typically nearly straight-sided or largest 

 in diameter just above the node, where there is a prominent ring, 

 and on the side opposite the bud a shoulder ; furrow broad and rather 

 deep, but narrower and shallower toward the top of the internodes. 

 Nodes rather large; typically smaller below the leaf-scar than above. 

 and increasing in size above until the lower limit of the internode 

 is reached ; two or three rows of rudimentary roots ; the depressed 

 ring forming the portion below the leaf-scar shallow on the side 

 opposite the bud but deeper immediately below it. Buds typically 

 long and more or less triangular in shape with the point either broad 

 or acute ; but sometimes about as broad as long, more or less ovate 

 and acute-pointed; adhering rather closely to the stalk; often in- 

 creasing in length on the standing stalk, l)ut not usually projecting 

 much through the scales; margin medium to narrow, and conforming 

 to the shape of the bud, or forming small lobes at the sides; usually 

 bearded near the point. Foliage abundant, medium green in color, 

 many dry leaves also retained. Leaf medium to l)i-oad, medium 

 length, erect growing. Leaf-sheath somewhat flattened at the throat, 

 glaucous; auricles medium to small; ligula medium length, with the 

 upper edge usually depressed in the center. Vestiture of leaf-sheath 

 medium stiff setae on the back. Vestiture of throat of sheath medium 

 long hairs on the auricles and edges of the base of the leaf, and some- 

 times a few on the adjacent areas of the face of the base of the leaf; 

 sometimes slightly pubescent on the face of the base of the leaf. ^lost 

 important distinguishing characters the shape and size of internodes, 

 buds, and leaves. 



B-3859. — Habit inclining. Length medium. Diameter medium. 

 Shape of stalk more or less curved. Color wine to greenish-wine : 

 a glaufous ring on the lower half of the node. Internodes mediuiii 

 lengtli, nearly round in cross-section, varying in shape with different
