| Original Botanical Description or Link to | Perennial, monoecious herb with creeping stems, rooting at the nodes when in contact with the substrate, up to ca. 25 cm long, sparsely hairy with white hairs up to ca. 2 mm long. Stem creeping, internodes 1.5−4 cm long, greenish. Leaves alternate; stipules persistent, 12−13 × 5−8 mm, ovate, with an abaxially slightly prominent midrib projecting up to 5 mm at the apex, greenish-reddish, glabrous; petioles 8.5−18.5 cm long, terrete, red, sparsely to moderately hairy; lamina 6.5–12.5 × 5–10 cm, asymmetric, elliptic to suborbicular, base cordate and lobes slightly over-lapping, apex rounded, margin entire and undulate in the larger leaves, adaxial surface green to dark green, glabrous, abaxial surface reddish, glabrous;
primary veins 5–7, actinodromous, secondary veins craspedodromous. Inflorescences: protogynous; female inflorescences 1-flowered (female
flowers solitary), basal to male inflorescences, peduncles ca. 1 mm long, pale green, glabrous; male inflorescences composed of up to 7 partial
inflorescences, each partial compressed monochasial with up to 5 flowers, peduncles 2.5–5 cm long, pink, glabrous; bracts 5−10 × 3−5 mm,
ovate, midrib slightly prominent projecting up to 1 mm at the apex. Male flowers: pedicels 17–20 mm long, white-pinkish, glabrous; tepals 2, white and tinged pink at the margin, 9–11 × 11–14 mm, broadly ovate, base slightly cordate, margin entire, apex rounded; androecium of 24–27 stamens, yellow, filaments up to ca. 1.5 mm long, fused at the base for ca. 1 mm, anthers up to 1.5 mm long, obovate, dehiscing through unilaterally positioned slits that are ca. 1/2 as long as the anthers. Female flowers: pedicels 4–9 mm long, pale green, glabrous; tepals 5, subequal, white or white tinged pink, 10–14.4 × 6.5–12 mm, elliptic, margin entire, apex rounded; ovary (without wings) 8–11.5 × 7.5– 8.5 mm, ovoid, sometimes beaked at the apex, pale green, wings 3, subequal to unequal, one wing
larger than the other two, base rounded, apex cuneate, up to 8 mm long at the widest point (subapically to middle of the ovary), style up to 4 mm long, basally fused, 3–branched, each stylodium bifurcate in the stigmatic region,
stigmatic surface a spirally twisted papillose band, orange. Fruit: peduncle ca. 1 mm long; pedicels 4−6 mm long; seed-bearing part 10−17 × 8−9 mm(excluding the wings), ovoid, glabrescent, dehiscent, splitting along the wing attachment, wings subequal to slightly unequal, base rounded, apex subtruncate to rounded, up to 13 mm long at the widest point (subapically to middle of the seed-bearing part). Seeds barrel-shaped, ca. 0.3‒0.4 mm long. |
