Panicles terminal, bracteate, less than 4 cm long; bracts acute, mostly 1-2.3 mm long; branches flattened; pedicels 4-13 mm long; flowers unisexual, the buds ob­long; staminate flowers cylindrical in bud; calyx bilobed, spathaceous, splitting on one side and recurving to expose other parts, ca 1 cm long, greenish; petals 4, ± equaling calyx, white, free, to 2 mm wide, hooked inward at apex; stamens many, 5-7.5 mm long; filaments white; anthers minute, longitudinally dehiscent; pistillode to 1 mm high, with 4 sessile stigmas; pistillate flowers similar to stami­nate ones; ovary glabrous; styles 4, only slightly exceeding staminodia, persisting in fruit; staminodia numerous, ca 7 mm long. Fruits ± obovate, 1.5-2 cm long, 4-lobed (at least when dry), splitting to expose red interior when ripe, 4-carpellate, each carpel with one seed; exocarp usually with scurfy, lenticellate areas; seeds oblong, ca 7 mm long.
