lateral nerves above the basal pair, about 5 on each side of the 
midrib, distant, curved, anastomosing, the reticulations lax; 
petioles 6 cm long; stipules not seen. Inflorescences slender, 
narrowly paniculate, about 20 cm long, long-peduncled, casta- 
neous when dry, pubescent, the lower branches up to 4 cm in 
length. Flowers 15 to 18 mm long, their pedicels 6 to 10 mm 
long. Calyx tube somewhat cylindric, nearly glabrous, the lobes 
4 to 6 mm long, erect, ultimately spreading, narrowly oblong, 
obtuse, not at all cohering even in bud, hirsute inside. Ovary 
ovoid, subsessile, densely pubescent; style stout, pubescent, 
about 1 mm long, the stigmas somewhat spreading or recurved, 
thickly club-shaped, about 1 mm long, the carpels 8 or 4, nearly 
free. Anthers 10, sessile at the base of the carpels.

This species belongs in the group with Sterculia laevis Wall., 
from which it is distinguished by its caudate-acuminate leaves 
and the calyx lobes being much shorter than the calyx tube.
