 the lobes short and broad, obtuse or acute. Corolla fleshy, 

 thick, 9 mm. long, gibbous at the base, infundibular, 5-angled, 

 the teeth short and broad, erect or spreading. Filaments 

 inserted at the summit of the pilose tube, attached near the 

 base of the anther, which is wholly included, linear, 5 mm. long, 

 the mucn thickened black connective extending to the summit. 

 Disk tnick, fleshy, cup-shaped, with the mouth much con- 

 tracted. 



"A gnarled tree, 10 feet high. Top of San Lorenzo ridge, 

 about 7,500 feet, March (Herbert H. Smith, Colombia, No.

Apparently the same as Triana's No. 1653. 



Palicourea caloneura. 



Lower leaf-surfaces more or less pilose. Branchlets stout, 

 terete, purple, densely leafy to the summit. Interpetiolar 

 stipules 4 or 5 mm. long, broadly ovate and abruptly contracted 

 into a narrow summit, the broad lower portions connate. Peti- 

 oles 3 to 5 mm. long, stout, winged, narrowly grooved above, 

 the groove extended into the midrib. Blades 4 to 6 cm. long, 

 1.5 to 2.5 cm. wide, oblong, acute at both ends, sharply revolute 

 on the margin, thick, yellow-green, the venation lightly promi- 

 nent above, very strongly so beneath, the stout secondaries 15 

 to 17 on a side, widely spreading, then falcate, connected by 

 the crooked tertiaries, pilose with divaricate hairs. Thyrse 

 terminal, sessile, small, little exceeding the upper leaves, sparsely 

 subulate-bracted. Calyx 1.5 mm. long and broad, the tube 

 turbinate-campanulate, the teeth extremely short, obtuse. 

 Corolla-tube 5 mm. long, narrow, cylindrical, gibbous at the 

 base, strongly nerved, the throat 2 mm. long, campanulate, the 

 lobes 2 mm. long, lanceolate, acuminate, more or less recurved, 

 the tips inflexed. Stamens inserted at the somewhat contracted 

 summit of the tube, which is lightly pilose, the filaments short, 

 the linear anthers about as long as the corolla-lobes, attached 

 near the base to the filament, slightly exserted. Style-branches 

 a third the total length of the style, the branches flattened, the 

 stigmas with rounded summits. Disk large, the summit 

 rounded. 



"A shrub, 2 to 4 feet high, the flowers dull pinkish. Ex-
