cate, somewhat acuminate, persistent and somewhat accrescent 
in fruit, attaining a length of 2.5 cm, longitudinally 7-nerved, 
somewhat reticulate. Flowers sessile, white, 4.5 to 5 cm long, 
calyx about 12 mm long, at first 2-lobed, ultimately equally 5- 
lobed, the lobes oblong-ovate, acute or acuminate, 3 mm long. 
Corolla tube conspicuously pilose externally with long, weak 
hairs, the lower 18 mm narrow, cylindric, then widened. Fila- 
ments 12 mm long, glabrous, the anthers 2 mm in length, con-, 
nate. Staminodes filiform, glabrous, 5 to 6 mm long. Disk 
cylindric, glabrous, nearly 3 mm long, slightly crenulate. Ovary 
glabrous, the styles slightly pilose, the stigma oblique, 1 mm 
long, 3 mm wide. Fruit oblong, subcylindric, glabrous, 1.5 to

Along streams in damp forests at low altitudes. 
A species strongly characterized by its unbranched habit; by 
its opposite, subequal, long-petioled, entire leaves; and especially 
by its peculiar inflorescences which are axillary, short-peduncled, 
supplied with two conspicuous, persistent bracts subtending the 
usually three sessile flowers. The species is entirely glabrous 
except the conspicuously pilose corollas. It does not appear to 
be closely allied to any previously described species of the genus 
and is aberrant in the various sections of the genus as defined 
by C. B. Clarke, although apparently coming nearest to the sec- 
tion Coccineae.
