Leaves glabrous, ovate, acuminate, margin undulate or entire ; second- 
ary nerves 6 pairs; tertiary nerves parallel, not conspicuous, joined by 
reticulate veins., Anthers linear; appendix of connective very short. 
Ovary glabrous; style cylindric, articulate with ovary, stigma minutely 
papillose. Wings of fruiting-ealyx twisted, very unequal, the two largest 
7 to 13 cm long, with 10 to 12 prominent nerves, the third 6.5 cm long, 
the others much smaller. Fruit tomentose, acuminate ; base of fruiting- 
ealyx pubescent. The number of secondary nerves is rather variable as is
