Inflorescences interfoliar; peduncle 8-15 cm long, recurved, flattened, spiny; prophyll 14-19 cm long; peduncular bract to 30(-40) cm long, persistent, moderately to densely covered with blackish or brownish, somewhat soft spines interspersed with straight black spines; rachis to 8 cm long, densely spiny; rachillae 25-89, to 14 cm long, filamentous, densely to moderately covered proximally with spinules; triads more or less regularly arranged (but often with solitary staminate flowers interspersed) on proximal ca. half or more of rachillae, and there tending to be absent from adaxial side of rachillae (paired or solitary staminate flowers only on distal ca. half of rachillae); staminate flowers 2-3 mm long; sepal lobes 0.5-1 mm long; petals 2-3 mm long; stamens 0, 3, or 6; pistillode absent; pistillate flowers 4-7 mm long; calyx cupular, 1-1.5 mm long, glabrous; corolla urceolate, 3-5mm long, spinulose; staminodes absent; fruits 1.2-2 cm diam., broadly obovoid, shortly rostrate, yellowish, orange, or red, with soft spinules; mesocarp starchy; endocarp obovoid, the sterile pores slighly displaced longitudinally; endocarp fibers few or absent; fruiting perianth with lobed calyx much shorter than the lobed corolla, without staminodial ring.

    Distribution
    The Guianas and Brazil (Amazonas, Pará); lowland rain forest on terrafirme or near streams in places liable to inundation, 200-260 m elevation. Near Manaus this species is usually seen in low, wet places near streams, but in French Guiana it is reported to occur on well drained slopes (de Granville, 1997); in Suriname it occurs in both habitats (Wessels Boer, 1965).
