A shrub about 2 m high, the branches rather stout, terete, brown, 
glabrous, the branchlets rather densely brown- or ferruginous-hirsute. 
Leaves opposite, coriaceous, elliptical-ovate or oblong-elliptical, 3 to 6 
cm long, 1.5 to 2.5 cm wide, the upper surface shining, glabrous except 
the somewhat pubescent midrib, the nerves strongly impressed, the 
lower surface with scattered short hairs, the midrib and nerves hirsute, 
the apex shortly acuminate, the base acute or somewhat rounded ; nerves 
6 to 8 on each side of the midrib, very prominent; petioles stout, densely 
ferruginous-hirsute, 1 mm long or less; stipules ovate, hirsute, 2 to 3 
mm long. Panicles terminal, congested, 3 to 4 cm long, very densely 
ferruginous-hirsute, the bracts narrowly oblong-lanceolate, hirsute, 4 mm 
long, the bracteoles similar but smaller. Calyx hirsute, 3 mm long, the

teeth.

Arbuscula 1 ad 3 m alta; ramis, ramulis, subtus foliis, paniculisque 
plus minus hirsutis; foliis membranaceis, oblongo-ellipticis, leviter falca- 
tis, usque ad 25 cm longis, apice acuminatis, basi longe decurrentibus 
nervis utrinque ca. 10 ; calycis segmentibus anguste lanceolatis, hirsutis, 
1.5 cm longis, persistentibus, sepala foliaeea alba. 
A shrub 1 to 3 m high, more or less hirsute. Branches reddish-brown, 
terete, the younger ones grayish-brown, hirsute. Leaves membranaceous, 
oblong-elliptical, slightly falcate, 15 to 25 cm long, 6 to 10 cm wide, 
nearly glabrous above, except the slightly hirsute midrib and nerves, 
somewhat shining, the lower surface paler, hirsute on the midrib and 
nerves and with scattered hairs on the lamina, the apex rather strongly 
acuminate, the base long and narrowly decurrent-acuminate, equilateral ; 
nerves about 10 on each side of the midrib, distinct ; petioles 2.5 cm long 
or less; stipules 1 cm long, ovate, long-acuminate. Panicles terminal, 
hirsute, the bracts 1.5 to 1.8 cm long, hirsute, cleft into three long, 
acuminate, narrow segments. Calyx segments persistent, narrowly lan- 
ceolate, about 1.5 cm long, 2 to 3 mm wide, with long spreading hairs,
