Leaves oblong to oblong-ovate, distinctly inequilateral, 7 to 10 
cm long, 3.5 to 4.5 cm wide, the upper surface glabrous, some- 
what shiny, somewhat narrowed upward to the obtusely rounded 
apex, the base somewhat obliquely cordate, the sinus shallow, 
narrow, the margin on the narrower side usually with 1 or 2 
short obtuse lobes, on the broader side with from 2 to 4 similar 
lobes or undulations ; basal nerves usually 6, slender, distinct ; pet- 
ioles slender, 10 to 13 cm long. Peduncles 18 to 24 cm long, 
glabrous, dichotomously branched at the apex, the primary 
branches up to 3 cm in length, few-flowered. Flowers pink, the 
sepals of the staminate ones broadly ovate, rounded, about 14 
mm long, 11 mm wide. Petals equaling , the sepals, narrowly 
oblong, 4 mm wide. Pistillate flowers as large as the staminate 
ones, the young capsules equally 3-winged, about 14 mm wide 
and 10 mm long including the wings, base rounded, apex some- 
what truncate.

In the form and characters of its leaves this species is remote 
from all other described ones of the section and is easily recog- 
nized by its usually oblong, rounded, obtuse leaves, which have 
a few short rounded lobes or undulations on each side.
