Description

Small palm solitary or clustering, with a spiny trunk to about 3 m. tall, and 8 cm. in diameter. Leaves are pinnate, slightly recurved and up to 1.5 m. long, with up to 60 pairs of leaflets. It has a white inflorescence, and brown fruit.

Stems solitary or clustering, but usually cespitose (growing in tufts or clumps), 4-10 m tall, 5-9 cm in diam., spiny on internodes. Leaves 6-9 per crown; leaf spines somewhat clustered, black, to 3 cm long, often in 3 longitudinal rows on petiole, on abaxial surface of rachis, fewer on adaxial surface; sheath to 40 cm long; ocrea not seen; petiole 30-90 cm long; rachis 0.8-2 m long; pinnae 46-67 per side, irregularly arranged in obscure clusters, spreading in different planes, linear, unequally bifid with midrib terminating subapically, spinulose along the margins; middle pinnae 35-39 x 1.7-2 cm. Inflorescences interfoliar; peduncle 10-19 cm long, recurved, spiny; prophyll 12-16 cm long; peduncular bract 30-48 cm long, moderately to densely covered with black spines to 3 cm long; rachis 7-15 cm long; rachillae 28-45, 15-17 cm long, at anthesis covered with brown, moniliform trichomes; triads irregularly arranged among paired or solitary staminate flowers; staminate flowers about 2 mm long; sepal lobes to 1 mm long; petals to 2 mm long; stamens 6; pistillode small; pistillate flowers 1.5-3.5 mm long; calyx annular, 0.5-1 mm long; corolla cupular, 1-2 mm long; staminodes absent; fruits 1.3-1.5 cm in diam., depressed-globose, red; mesocarp mealy or oily; endocarp turbinate, the sterile pores slightly displaced longitudinally; endocarp fibers absent; fruiting perianth with small calyx and three-angled, 2 mm long corolla, without staminodial ring.

Bactris plumeriana is diagnosed by its linear, 46-67 pinnae per side, and depressed-globose, red, fruits 1.3-1.5 cm diameter. Salzman & Judd (1995) have given a detailed description and discussion of relationships of this species. Bactris ? chaetophylla, listed as an ambiguous name by Salzman & Judd, is a synonym of B. plumeriana. The type and description are based on a juvenile leaf. (Henderson, A.J. 2000)/Palmweb.

Culture

Sunny, moist, tropical to warm, sub-tropical position. Doesn't mind wet low lying areas.
