narrowly elliptic, 6.5-20 by 1.5-7.5 cm; base cuneate to slightly attenuate, basal glands absent;
margin lowly undulate to lowly glandular-crenate, marginal glands regular, small, greyish or
blackish; apex acuminate to cuspidate; blade thin, lowly granular above and beneath, dull, not
brittle, drying greyish green to yellowish green above and beneath, nervation lighter beneath,
very sparsely puberulous, midrib and nerves (sparsely) hirsute, glabrescent; dots irregularly set,
fine, greyish, mostly indistinct; disc-like glands occasionally few, small, along margin. Nervation:
midrib slightly prominent above, prominent beneath; nerves 8-10 pairs, slightly prominent to flat
above, prominent beneath, marginal arches distinct, 1.5-2.5 mm from the margin; tertiary veins and
venation often distinct, rather densely reticulate, slightly prominent to flat above, (slightly)
prominent beneath. Inflorescences axillary or just below the leaves. Staminate inflorescences 1-4
clustered together, 5-22 by 2-3.5 mm, (sparsely) puberulous; peduncle 0.5-1.5 by 0.7-1 mm; bracts
broadly triangular, 0.4-0.7 mm long, inconspicuous, very sparsely hairy outside, glabrescent,
glabrous inside, margin ciliate; glomerules ellipsoid, consisting of 7-10 densely set flowers, c.
2 by 0.5 mm, spaced at 0.5-1 mm at base, apically slightly massed in a cylindric head; pedicel
absent. Staminate flowers 0.3-0.7 mm long; sepals (3 or) 4, obovate, 0.2-0.4 mm long, connate at
base, glabrous, margin ciliate at apex; stamens 2 (or 3), 0.3-0.6 mm long, slightly exserted;
anthers 0.1-0.2 mm long, connective glabrous; pistillode absent. Pistillate inflorescences 1-3
clustered together, 2-7 by 0.7-1 mm, (sparsely) puberulous; flowers single at apical end of rachis;
bracts broadly triangular, 0.5-0.8 mm long, sparsely puberulous outside, glabrous inside; bracteoles
ovate, c. 0.5 mm long, sparsely hirsute outside, glabrous inside; pedicel 1.5-2 mm long, puberulous.
Pistillate flowers 1.5-3 mm long; sepals 5 (or 6), ovate, subequal, reflexed, 1.2-1.5 mm long,
fleshy, sparsely puberulous; ovary ellipsoid, 1.5-2.5 mm, 3-locular, slightly punctulate, sparsely
puberulous to subglabrous; stigmas sessile, broad, apically lowly lobed, flattened on top of ovary,
straight, 0.5-1 mm long, lowly papillate above, glabrous, connate to the ovary beneath.
Infructescences 3-11 by 0.8-1.2 mm, sparsely puberulous, glabrescent; fruiting pedicel 2-6 mm long.
Fruits juicy, globose, often with sunken stigmas, not stiped, not beaked, 9-15 by 10-15 mm, smooth,
drying light or brownish yellow, sparsely puberulous to glabrous; pericarp 0.5-3 mm thick, fleshy;
septae and column glabrous. Seeds 2-4, half-terete, ellipsoid, 8-11 by 6-9 by 3-5 mm. [from Flora
