ovate, acute, recurved, the style exserted about 2 mm., the 

 stigma truncate. Stamens 1.5 cm. long, the filaments distinct, 

 half as long as the anther, narrow, flattened, attached 3 mm.

"A vine to 25 or 30 feet, with bright red flowers, in damp 

 forest and thickets near streams. Las Nubas, 4,500 feet, Decem- 

 ber 2." (Herbert H. Smith, Colombia, No. 1554). 



Cybianthus foliosus. 



Glabrous, the stems erect, very stout, purple, striate, sparsely

 broad, thinly margined and keeled, attached by a broad base. 

 Blades 10 to 15 cm. long, 4 to 6 cm. broad, oblong to oblance- 

 olate, with short-acuminate base and a very short obtusish 

 point at the summit, entire, thin, deep-green and profusely 

 black-dotted, the dots coarse, the very finely anastomosing 

 slender venation prominent beneath, slightly so above, the 

 principal secondaries numerous, very slender, strongly ascend- 

 ing, faintly connecting close to the thinly revolute margin. 

 Panicles axillary, shorter than their leaves, very slenderly 

 peduncled and branched, loose and open, the bracts minute, 

 ovate, the flowers mostly in threes at the ends of the branchlets, 

 slenderly pedicelled, the pedicels mostly longer than the flowers, 

 dilated and angled at the summit. Calyx-tube crateriform, 

 2 mm. broad and half as long, the lobes 2 mm. long, ovate, 

 obtuse, thin. Corolla parted nearly to the base, the lobes 3 

 mm. long, oval with rounded summit, thin, purple striate. 

 Stamens 5, shorter than the corolla, the slender filaments shorter

 thick, the midrib sharply prominent beneath, narrowly chan- 

 nelled on the upper surface, the very numerous and very slender 

 secondaries lightly prominent on both sides, nearly straight, 

 faintly anastomosing near the margin, the venation finely 

 reticulate. Panicle terminal, shortly and stoutly peduncled, 

 loosely branched and flowered. Flowers not seen. Pedicels 

 of very young fruits mostly deflexed, 3 mm. long, thickened 

 upward, nerved and minutely roughened. Calyx a third the
