with the upper edge depressed in the center. Vestiture of leaf- 

 sheath man}^ sharp, stiff setae. Vestiture of throat of sheath straight, 

 rather short hairs on the auricles, adjacent edges of the leaf and leaf- 

 sheath, and sometimes on the face of the hase of the leaf. IMost im- 

 portant distinguishing characters color, striped leaf-sheath, and form 

 of the buds. 



Yellow Caledonia. — Habit erect. Length long. Eliameter above 

 medium. Shape of stalk straight. Color greenish -yellow, tinged with 

 red on the upper internodes and where exposed to the sun ; with fine, 

 dark-colored cracks in the epidermis ; more or less glaucous on the 

 lower part of the node. Internodes long and quite uniform ; typically 

 straight-sided, but sometimes slightly constricted and sometimes 

 slightly sub-conical ; no furrow. Nodes rather large : the portion 

 above the leaf-scar long and about the same diameter as the inter- 

 nodes; about four rows of rudimentary roots; leaf -scar projecting 

 prominently from beneath the bud. Buds usually small but uniform, 

 about as broad as long, typically ovate to sub-elliptical in outline, 

 plump and with a margin narrow but uniform as to width, and fol- 

 lowing the shape of the bud ; scales of fine texture ; bearded at the 

 tip and sometimes pubescent on the sides. Foliage abundant, green 

 leaves inclined to adhere to the stalk rather far down, but the dry 

 leaves are shed; medium dark in color. Leaf broad, long, tapering 

 medium abruptly into a point. Leaf-sheath large in circumference at 

 the throat, color light green with sometimes a pinkish tinge ; auricles 

 small; ligula medium length, with the upper edge depressed in the 

 center. Vestiture of leaf-sheath a few setae in a line on the back. 

 Vestiture of throat of sheath short hairs on the auricles, adjacent 

 edges and face of the base of the leaf, and sometimes back of the 

 ligula; also sometimes finely pubescent on the face of the base of the 

 leaf. INIost important distinguishing characters color, cracks in the 

 epidermis, and form of the internodes. 



B-347.— Habit erect to reclining. Length medium to long. Di- 

 ameter medium to large. Shape of the stalk usually straight. Color 

 yellowish-green, with a tinge of red on the upper internodes; more 

 or less glaucous; marked with irregular, light-colored spots, appar- 

 ently caused l)y a loss of the cuticle. Internodes slightly flattened, 

 medium length, usually staggered ; sides sometimes straight but 

 usually more or less tumid, mainly on the side opposite the one on 

 which the bud grows. Nodes medium to large ; the leaf-sear pro- 

 jecting out a little on all sides; above the leaf-scar often a little 

 smaller than the portion of the internode just above -it ; rudimentary 

 roots two to five rows. Buds typically long in comparison to width,
