A tree, according to Mr Brown, with terete, yellowish-brown branches, the 
younger ones subpubescent, their extremities hairy with thick brown 
hairs, the rest glabrous. Leaves placed in whorls of 4 or 6, lingulato-ob- 
long, placed upon short footstalks, erecto-patent, quite entire at the mar- 
gin, and slightly recurved, the upper side glabrous, dark green, the un- 
der side white, with short cottony pubescence ; the extremity obtuse or 
even retuse, muticous, or in the younger ones sometimes terminated with 
a short hair or bristle-like point. Midrib prominent beneath, and gi'een, 
glabrous, in the uppermost leaves covered with numerous brown bristles. 
Amentum terminal, appearing lateral only in consequence of the putting forth 
of a new shoot beneath it, cylindrical and elongated, densely clothed with 
truncated, red-brown, very silky scales or bracteas; these are placed in 
threes (two small and one larger one) beneath each pair of flowers, and 
upon a hairy receptacle. 
Flowers in pairs : each of 4 petals, forming a tube by the cohesion of the pe- 
tals or leaflets of the perianth, which afterwards become more or less sepa- 
rated, curved, especially towards the extremity. Lamince ovate, for some 
time cohering together, very concave within, the margin thickened, 
and tawny; the claws slender, yellowish, their base hairy. Stamens placed 
one within the concave extremity of each petal. Filament short : Anther 
oblong yellow. Pistil single. Germen roundish, small, hairy at the 
top, the base surrounded with 4 small, oblong, obtuse, upright scales. 
Sti/le yellowish-green, very long and singularly rigid, exceeding the co- 
rolla in length, bursting with its middle through the side of the corolla 
with a remarkable curvature, but retained at its extremity for gome time 
within the closed laminae of the corolla. Stigma ovato-oblong, yellow.
