uniformly black and shining on both surfaces when dry, lanceo- 
late to oblong-lanceolate, 18 to 25 cm long, 5 to 7 cm wide, sub-

Whitford & Hutchinson, November 29, 1907, on forested ridges, 
altitude about 30 meters. : 
This species is strongly characterized by its elongated, many- 
nerved leaves; its peduncled, trifid inflorescences; its 5-merous 
flowers; and short corolla-tube which is not bearded at the 
throat, the lobes being twice as long as the tube. The plant is 
entirely glabrous except the sparingly puberulent inflorescence.
