Illustration : Harden (2000: 502). 
Shrub or small tree, 1.5-5(-9.5) m tall; bark 
grey, smooth; branching sparse to abundant, 
branchlets usually zig-zag, some very small 
leaves usually present near base of branchlets. 
Leaves distichous, petiolate; petiole 3-7 mm 
long, reddish, weakly marginate, flat on 
adaxial surface. Lamina chartaceous, elliptic, 
often somewhat asymmetrical, (1.5-) 4.8-12.5 
cm long, (0.7-) 1.5-3.6 cm wide; apex obtuse 
to acuminate, base cuneate, adaxial surface 
dull to glossy green, abaxial surface paler, 
glabrous except for scattered scales, margins 
may be undulate and weakly recurved, midrib 
depressed on adaxial surface, prominently 
raised on abaxial surface; lateral veins may be 
relatively inconspicuous, 13-25 pairs on either 
side of the midrib irregularly looping near the 
margins; glands of of both types, irregularly 
globular, reddish and more frequent near 
the margins, often visible as bumps on the 
adaxial surface, when lineate appearing black 
with a length:width ratio up to 10:1, chiefly 
visible on the abaxial surface, the latter are 
not always present in every leaf. Inflorescence 
an axillary raceme, appearance depends 
on the spacing of the pedicels, may appear 
subumbellate or congested, to 2 cm long; 
flowers 3-7(-10) per inflorescence; peduncle 
and pedicels reddish; pedicels filiform, 2- 
5(—10) mm long, scattered glandular papillae 
often present, glands dark red, globular to 
shortly lineate, density variable; subtending 
bracts chartaceous and soon caducous, c. 
1.5 mm long and 0.75 mm wide at base; 
glands globular reddish, margins scarious. 
Flowers 5-merous, 2-3 mm long. Calyx 5- 
lobed, green; tube 0.1-0.2 mm long, lobes 
triangular 1-1.5 mm long, 0.75-1 mm wide at 
base, glands globular red to dark red, margins 
scarious. Corolla rotate, white to pinkish-red; 
tube 0.2-0.4 mm long, lobes usually widely 
spreading after anthesis, 2-2.5 mm long, 
1-1.5 mm wide, median portion of lower half 
of lobe thickened on adaxial surface, papillae 
present, uniseriate hairs present at junction 
of corolla-tube and lobes; glands pale to dark 
red, margins scarious. Stamens opposite the 
petals; base of filaments fused to form a small 
rim, free portion flattened, c. 0.2 mm long; 
anthers 2-locular, cordate-sagittate tapering
