    General Description
    Dwarf, clustering, unarmed, pleonanthic, dioecious palm. Stem very slender, internodes long, ringed with leaf scars. Leaves pinnate or entire, bifid and pinnately nerved; sheaths slender, tubular, not splitting opposite the petiole; petiole slender; rachis ± triangular in cross-section; leaflets when present only 24 per side, with broad insertions, thin, smooth, lanceolate, midrib and sometimes another pair of veins larger, transverse veinlets not apparent. Inflorescences interfoliar, staminate and pistillate inflorescences superficially similar, branching to 1(–2) orders; peduncle elongate; prophyll tubular; peduncular bract 1, tubular, it and the prophyll included within the sheath or exserted and exceeding the peduncle; rachis shorter than the peduncle; rachillae slender, few and subdigitate to numerous, bearing low membranous bracts, floral bracteoles not evident. Staminate flowers in acervuli of 2–6; sepals 3, briefly connate and markedly gibbous basally, distinct distally and the lobes ± hooded at least in bud, the margins usually thin; petals 3, thin, nerveless when dry, valvate, spreading to recurved at anthesis; stamens 6, the filaments erect in bud, distinct, anthers medium with rounded ends, fleshy connectives very short; pistillodes 3, distinct or somewhat connate. Pollen ellipsoidal, slightly asymmetric; aperture a distal sulcus; ectexine tectate, very finely striate, aperture margin similar or slightly perforate; infratectum columellate; longest axis ranging from 26–32 µm; post-meiotic tetrads tetrahedral, occasionally tetragonal [1/1]. Pistillate flowers solitary or in vertical pairs; sepals 3, connate in a low, 3-lobed cupule, gibbous basally; petals 3, imbricate, gibbous, about twice as long as sepals; staminodes 3, minute; gynoecium subglobose, trilocular, triovulate, stigmas 3, reflexed, ovule pendulous, form unknown. Fruit ellipsoidal, with basal stigmatic remains and remnants of abortive carpels, orange-red at maturity; epicarp smooth, mesocarp thin, lacking fibres, endocarp membranous, not adherent to the seed. Seed with a single raphe branch ventrally curving over the top and a side branch curving around each lateral surface, endosperm homogeneous; embryo lateral slightly below the middle. Germination and eophyll unrecorded. Cytology: 2n = 28.
    Diagnostic
    Diminutive pinnate-leaved dioecious undergrowth palms from rain forest in South America; the leaves are often entire bifid; inflorescences are very small with flowers in acervuli.
    Distribution
    A single species with three varieties, each confined to three separate basins of the western Amazon in Brazil, Peru and Bolivia.
    Biology
    This is a palm of the undergrowth of lowland rain forest on terra firme (Henderson 1995).
