Description:
Species Description - Monoecious straggling shrub or tree, 5-20 m tall, reaching a dbh of 20 cm, often with rather long (sarmentose) branches hanging over other vegetation; young branchlets terete but flattened at the nodes, very sparsely covered with appressed stellate-lepidote hairs, glabrescent. Leaves opposite; petioles 1-2 cm long; lamina drying grayish brown, chartaceous, oblong, 13-20 X 3-5 cm, the base obtuse, the apex acuminate to cuspidate, the tip 0.5-1.5 cm long, older leaves glabrous on both surfaces except occasional stellate-lepidote hairs on the midrib base, with 14-15 pairs of secondary veins, the veins very fine and regularly spaced, the margin entire. Cymes 2.5-7 cm long (including the elongated pedicels of male flowers), covered with minute silvery stellate-lepidote hairs, with 15-20 flowers, the basal 3-5 flowers female, the distal 10-12 flowers male. Fresh flowers greenish yellow, yellow, or pale orange; male flowers subglobose, 2.5-3.1 mm in diam., 2.2-2.5 mm high, the tepals forming a narrow upright rim, the floral roof a little-developed membrane; pedicels elongating gradually during anthesis and becoming up to 4 cm long; stamens 14-15, thick-fleshy, when emerging from the floral roof at maturity arranged in a rosette; female flowers subglobose, 22-2.5 mm in diam., 2.3-2.5 mm high, the tepals forming a narrow upright rim, the floral roof broadly conical and densely tomentose; styles ca. 6. Fruiting receptacle globose, about 1.2 cm in diam., fresh and immature green, mature orange; drupelets ca. 5, lacking a stylar aril.

Discussion:
Siparuna sarmentosa is readily recognized by its narrowly oblong leaves and extremely fine secondary and tertiary venation. The only species with similar leaves is S. cymosa from eastern Amazonia and BahÃa, but that has cymes with smaller, more numerous flowers, shorter pedicels, and fewer stamens (4-9 vs. 14-15).
