Trees 30 to 40 m high, the' younger branchlets densely covered with 
brush-like, fascicled, tawny, stiff hairs; stipules rose-colored, up to 15 
cm long, bi-ushy-hirsute ; leaves of younger branchlets very large, 30 fo 45 
cm long and of a thinner texture, the older ones smaller, broadly oblong 
to ovate-oblong, obtuse or rounded at the somewhat narrowed base, on a 
5 cm brushy-hirsute petiole, shortly acuminate, chartaceous, or almost 
coriaceous, upper surface along the impressed nerves and lower surface 
eveiywhere pubescent with short, tawny, stellate and simple hairs. 
Flowers showy, rose-colored, forming simple, short, axillary racemes 
covered with brush-like, fascicled, stiff hairs; calyx tawny-tomentose with 
stellate hairs ; petals oblong, blunt, several times the length of the calyx, 
thickly covered on their outer surface with stellate hairs; fruiting calyx 
ovoid, about 2.5 cm in diameter, terete, the two wing-like lobes 17 to 20 
cm long, 3 to 4 cm broad, with three prominent longitudinal vems and 
numerous, more or less distinct, transverse veins. Fruit hard and heavy, 
more or less fibrous inside, and containing resin; upper portion of the 
fruit with or without .small obtuse, rounded protuberances, which 
alternate with the lobes of the calyx. 
Dipterocarpiu^ ivarhurgii Brandis and D. Jaslopodus FerK were de- 
scribed as belonging in the Section TuhercuJati, but they were described 
from fragnientai'y or immature material, which does not present very 
conclusive evidence of their belonging to that section. Leaf and fruit 
characters of D. pilosn^, as shown by our collections, have shown such 
a range of variability that it has seemed to me best to refer the above 
names to synonymy. It is possible that more complete material may 
show them to be good species, but at present I can see no reason for 
l^eeping them distinct.
