A dioecious shrub up to 7 m in height, prominently stellate- 
tomentose. Branches terete, rather stout, 5 to 10 mm in diam- 
eter, the leaf-bearing parts densely covered with pale-brown- 
ish, soft, stout, densely stellate-tomentose papillae about 5 mm 
in length, the younger petioles often with similar papillae. 
Leaves alternate, broadly ovate, long-petioled, chartaceous, 13 
to 36 cm long, 10 to 25 cm wide, the base broadly rounded 
and peltate, the petiole inserted 1.5 to 5 cm from the margin, 
the apex prominently caudate-acuminate, the margins suben- 
tire to irregularly dentate, the teeth never large, usually mi- 
nute, the upper surface eventually glabrous, or the nerves 
somewhat stellate-tomentose, pale-olivaceous or brownish-oliva- 
ceous, the lower surface very densely stellate-tomentose with 
grayish to subferruginous, short hairs; petioles up to 18 cm 
in length, those of the smaller leaves very much shorter, some- 
times but 3 to 4 em in length, uniformly and densely stellate-

papillae. Staminate inflorescences about 20 cm long, densely 
Sstellate-tomentose, sparingly branched, the branches 3 cm long 
or less. Pedicels about 3 mm long. Sepals 4, oblong-elliptic, 
2.5 mm long. Stamens about 70, their filaments 2 mm long. 
Pistillate inflorescences solitary, simple, peduncled, the flower- 
bearing part dense, cylindric, spiciform, 4 to 5 cm long, 1 to
