A shrub or small tree; the branches and young shoots glabrous or (var. pubescens) 
pubescent. Leaves subcoriaceous, from obovate-lanceolate to oblong-lanceolate, inequila- 
teral, sub-faleate, shortly acuminate, remotely and minutely mueronate-serrulate, nar- 
rowed and unequal at the base, shining and glabrous except the midrib and nerves 
which, on both surfaces, are usually more or less pubescent; nerves 5 to 8 pairs, spread- 
ing or sub-erect, thin but prominent beneath; length 2:5 to 5 in, breadth 75 to 2:5 
in., petiole “25 to 35 in.; stipules persisteat, linear-lanceolate, pubescent, about as long 
as the petioles. Male inflorescence small, supra-axillary, 1- to 4-branched, uniparous, 
tomentose, bracteolate, cymes not much longer than the petioles, flowers ‘25 in. in 
diam. Sepals 5, rotund, the 3 external slightly imbricate, pubescent; the 2 inner much 
imbricate, glabrescent. Petals 5, smaller than the sepals, fleshy, with long white silky 
hairs externally, and each internally with a small oblong scale. Filaments short, thick, 
sericeous, the connective reniform ; the anther cells small, remote from each other. 
Ovary 0. Female flowers solitary, supra-axillary, on glabrous pedicels “5 in. long. Sepals 
and petals as in the male, stamens without pollen; ovary ovoid, tomentose; stigmas 3, 
large, flat, bifid, reflexed. Fruit on a pedicel “5 in. long, solitary, axillary, depressed. 
globular, minutely rugose, and velvetty tawny-tomentose; about 1 in. in diam. or 
less; pericarp dry, thin. Seeds 3 or 4, plano-convex, *5 in. long.

This varies considerably as to size of leaf and fruit and in the amount of pubescence. In some 
specimens of the male plant the leaves towards the apices of the branches are much reduced in size. 
The form which has larger, more pubescent leaves may be separated as a variety, and farther 
. acquaintance with it may prove that it is separable as a species.
