scar about ;is large- or larger than the internodes, usually a prouiineiit 

 ring at the upper limit of the node ; two to three row* of rudimentary 

 I'oots. Buds typically variable in size and shape and more or less 

 triang'ular in shape, usually short for their width, sometimes having 

 the appeai'ance of being five-sided: margin typicnlly narrow and 

 uniform in width with the sides of the bud. edges either straight, 

 eurved or irregular; lol^es small or none. Foliage abundant ; retained 

 well down on the stalk, including some of the dry leaves; medium 

 to dai'k in color. Leaf medium to bi-oad. medium length, taiici-ing 

 into an acute point of medium length. Leaf-sheath almost round 

 at throat, glaucous; auricles small, sometimes long-pointed on one 

 side of the stalk ; ligula medium to short, with upper edge rounded 

 in outline. Vestiture of leaf-sheath a few setae which are short and 

 soft. Vestiture of throat of sheath medium coarse hairs on the auri- 

 cles, edges and surface of base of the leaf, and sometimes a few extend- 

 ing to the area behind the ligubi. Most impoi'tant distinguishing 

 characters color and the form of the internodes and buds. 



B-208. — Habit inclining to reclining. Length medium to short. 

 Diameter medium to large. Shape of the stalk usually curved, ("ohu* 

 medium green, more or less glaucous. Internodes nearly round in 

 cross-section, typically short and tumid, and with a prominent 

 shoulder on the side oj)posite the one on which the bud occurs: fur- 

 row very shallow. Nodes small; the portion above the leaf-scar a 

 little longer, and larger in circumference than that below; tlie de- 

 pi'essed ring forming the poi'tion below the leaf-scar medium depth 

 but nai'i-ow. deepest below the bud. Two or three rows of rudiment- 

 ;iiy roots. I>uds typically having stai'ted through the scales ;ind pro- 

 jecting out from the stalk in a globoid to conical point : before 

 staiting short and swollen: when very young typically flat, very 

 broad and ovate-cuspidate in outline, with the margin extending 

 across the top or rather than on the sides; lobes typically well-marked. 

 Foliage medium in amount, rather daik in coloi'. Leaf medium to 

 siiort. lu'oad. gi-owing semi-erect, tajx'i'ing medium al»ruptl\' into a 

 point. Leaf-sheath bioad. almost I'ound at the thi-oat. light green 

 to reddish-gj-een in color: auricles medium to small: ligula medium 

 length, with the upper al^xi' slightly dei)i-essed in the c(Miter. \'es- 

 titure of leaf-sheath many long, medium stitf setae, not closely ajt- 

 pressed. \'estitui-e of thi'oat of sheath metlium soft hairs on the 

 auri<'les and edges of the base of the leaf, and more or less on the 

 adjacent ai-ea of the face of the leaf. .Most im|»oi-tant distinguishing
