Tree, to 7-8 n1 tall. Terminal buds pubescent with yellowish brown to reddish brown,
erect wavy hairs. Twigs terete, con1pressed when young, densely pubescent with erect, long
wavy hairs, less densely to glabrescent when older. Leaves opposite, rarely subopposite;
petioles (0. 7) 1.1-1. 7 mm, flat or slightly canaliculate above, pubescent with erect wavy

firmly chartaceous, narrowly elliptic, n1argin son1etimes slightly undulate, (7) 12-20 (24) x
(2) 2.5-5 (6) em, base cuneate, not inrolled, apex acute; leaf surface glabrous on both sides,
lower leaf surface not glaucous; midrib immersed above, raised below, secondary veins ( 13)
14-22 pairs, slightly raised above, raised below, tertiary veins not percurrent, ramification
coarse, square-like with free veinlets, slightly raised above, raised below. Inflorescences
axillary, paniculate, 2.5-6 (10) em, pubescent with erect hairs, with 30-60 flowers per
inflorescence; flower pedicels of the lateral divisions 1.2-2 mm long, pedicels of the central
flowers up to 2.7 mm long. Flowers 2-2.7 mm long, ca. 2.5 mm in diam; tepals 6, equal,
ovate, 1.3-1.7 mm long, 0.9-1.3 n101 wide, outside pubescent with erect hairs, inside
sparsely pubescent with appressed to erect hairs; stamens 9, outer six filaments ca. 0.4 mm,
innermost three filaments ca. 0.5 nun long, filmnents sparsely pubescent, outer six anthers
0.6-0.8 min long, innermost three anthers ca. 0.5 mm long, all the anthers 2-celled, apex of
the outer six anthers roundish to acute, apex of the innermost three anthers truncate, apex of
all the anthers glabrous, glands of the innennost three stamens globose; staminodia 3,
cordate in outline, 0.4-0.6 n101 long; pistil ca. 1.2 mm long, glabrous or slightly pubescent,
ovary slightly longer than and gradually narrowed into the style or sometimes the border

fruit pedicel, fruit pedicels constricted at the base, free from lenticels and darker than the
infructescence axis.
