Inflorescences: interfoliar but often infrafoliar in fruit, erect to spreading; peduncles 15-30 cm long, erect or sometimes curved in fruit, pale or greenish in flower, red-orange in fruit; bracts 5-6, green, thin-papery, turning brown in fruit, uppermost opening long-oblique and exceeding peduncle. Staminate forked with a very short rachis 1-2 cm long or perhaps spicate; flower-bearing portion of rachillae 20-30 cm long, I cm wide with flowers at anthesis, pendulous. Pistillate spicate; rachis or flower-bearing portion 10-15 cm long, stiff and erect in bud and in flower, becoming downward-pointing and curved in fruit. Flowers: Staminate in 8 dense spirals, contiguous, brownish white; calyx prominent, 2 mm high, lobed, sepals connate basally, rounded to straight and broad apically, ± rectangular, 2 x 1.5 mm, thickened below across apex; petals 4 x 2 mm, valvate, ± fleshy, thickened along margins; stamens not exceeding petals, filaments 2.5 mm long, longer than pistillode, terete, anthers 1 x 0.5 mm, medifixed, at right angles to filament; pistillode 1.5 x 0.5 mm, columnar, slightly expanded apically and with 3 rounded lobes, 1/2 as high as stamens. Pistillate in densely packed irregular rows, contiguous, 3.5 x 2.5-3.5 mm, yellow; calyx prominent, 2 mm high, lobed, sepals connate basally, widely truncate apically, 2 x 0.5 mm, thicker apically; petals 3 x 2.5 mm, imbricate nearly to apex, cupped with a short tip at center; staminodes lacking; pistil 2.5 x 2.25 mm, subglobose, styles short or lacking, stigma lobes closed but ± triangular.
