Habit: solitary, erect, appearing stemless, to 1-1.5 m tall. Stem: 2-3 cm in diam., creeping or erect at or below ground level or covered with leaf litter, to 15 cm tall or long, prominently ringed, nodes congested, internodes 3-5 mm long. Leaves: 4-6 per crown, erect-spreading, pinnate; sheath to 15-30 cm long, long-obliquely open, splitting deeply opposite petiole and tubular only near base, green; petiole 30-45 cm long, much ribbed or striate laterally, flattened or slightly angled and green above, rounded and green below; rachis to 0.75-1 m long, slightly angled and green above, rounded and green below; pinnae 16-20 on each side of rachis, to 20-35 x 2.5-4 cm, linear-Ianceolate to lanceolate, falcate or slightly sigmoid, narrowly acuminate, contracted basally, regularly disposed, opposite or subopposite, lower margin decurrent on rachis, glabrous, bright green, a central prominent midrib above, 2 less prominent primary nerves on either side of this, indistinct secondaries between the primaries and midrib, 5 nerves prominent below. Inflorescences: interfoliar or less frequently infrafoliar, often arising from below leaflitter, erect-ascending, long-pedunculate; peduncles to 75 cm long, slender, erect, 1-1.5 cm wide at base and there ± flattened, 2-4 mm in diam. at apex and there rounded, greenish in flower, orange in fruit; bracts 5-10, prophyll to 2 cm long, 2nd bract to 2.5 cm, 3rd to 5 cm, 4th to 8 cm, 5th to 11 cm, 6th and 7th to 13 cm, 8th to 10cm, 9th to 6 cm, tubular, strongly longitudinally striate-nerved, membranous, acute and bifid apically, brownish or rotting away by anthesis and in fruit, upper one equalling peduncle. Staminate diffuse, flowering portion to 25 cm long and broad; rachis 15-20 cm long, green; rachillae 15-30, lower ones longest, these to 10-15 cm long, uniformly spreading and diverging from rachis at nearly right angles, drooping apically, green, slender. Pistillate few-branched; rachis 1-8 cm long, green in flower, orange in fruit; rachillae 4-9, these to 10 cm long, ± stiff, erect, parallel or slightly curving, rachillae green in flower becoming yellow-orange to orange in fruit. Flowers: Staminate in ± dense spirals, in immature bud 2 x 1 mm, near anthesis 3 x 2.5-3 mm, ± globose, green, abruptly short-pointed, slightly sunken; calyx 0.5-1 x 2 mm, prominently lobed, conspicuously brown-margined, sepals connate in basal 1/3, slightly flared and broadly rounded apically; petals 2.5-3 x 1.5 mm, valvate, free nearly to base, erect-spreading, acute; stamens 2 mm high, leaning away from and not exceeding pistillode, filaments 1 mm long, pale, anthers 0.5-0.75 mm long, bilobed; pistillode 2-2.5 mm high, columnar, pale, greenish apically and there sharply 3-lobed and enlarged. Pistillate in fairly dense spirals, 2.5 x 2-2.5 mm, ± globose, green, slightly sunken; calyx 0.5 x 2 mm, prominently 3-lobed, brown-margined, sepals free and separated basally, triangular, rounded to acute apically; petals 2.5 x 2.5 mm, cupped, imbricate nearly to apex, sharply acute and recurved slightly apically, thick; staminodes 1 mm high, acute, whitish; pistil 2-2.5 x 1.5-1.75 mm, inverse-conic, green; stigma lobes sessile, short, close, forming a pyramid-shaped structure, pale, shorter than petals. Fruits: 5-7 mm in diam., black, globose (oblong when immature); eophyll pinnate. Editing by edric. (Hodel, D.R. 1992)/Palmweb. Editing by edric.

Culture

It is best suited for the understory, of the warm temperate garden, but is very rare in cultivation, mainly because seeds are very difficult to obtain.

Comments and Curiosities

Chamaedorea are dioecious, male, and female flowers, on separate plants.

Etymology: Honors R. W. Schery, co-collector of the type.
