Discussion

  • The description is from Galeano (1986), who stated that C. murriensis is related to C. warscewiczii but differs in the leaves obovate in outline instead of ovate and the very large apical pinnae occupying more than half the rachis. Not cultivated, C. murriensis is apparently rare in the wild, being known only from the type locality and a few collections in the Darien region of adjacent Panama. (Hodel, D. 1992.

Biology And Ecology

  • Dense, wet forest; 700-1,500 m elevation. (Hodel, D. 1992. Chamaedorea Palms, The Species and Their Cultivation. The International Palm Society.)A

Etymology

  • Derived from the location where the species was discovered, the corregimiento de Murri in Colombia. (Hodel, D. 1992. Chamaedorea Palms, The Species and Their Cultivation. The International Palm Society.)A

Description

  • Habit: solitary or cespitose, erect, 2-3.5 m tall. Stem: 2-3 cm diam., green. Leaves: 7-10, pinnate; sheath 16 cm long, tubular, green, striated; petiole 5-6 cm long; rachis 42-50 cm long; blade obovate; pinnae 2-4 on each side of rachis, apical ones very large, 50 x 18-20 cm, occupying a little more than 1/2 rachis, elliptic, slightly toothed toward apex, 10-11-nerved, other pinnae 25-32 x 5-7 cm, lanceolate, sigmoid, acuminate, 4-7 cm apart, I prominent primary nerve per pinna, this yellowish, several secondaries and tertiaries, primaries total 13 on each side of rachis. Inflorescenses: simply branched. Staminate with peduncle 72 cm long, 3 mm wide; bracts 6, upper one 20 x I cm, tubular, membranous to papery, slightly striated; rachis 7-8 cm long; rachillae 14, these to 30 cm long, 1 mm wide, pendulous, rigid. Pistillate green in flower, red with mature fruits; peduncle 60 70 cm long, 4 mm wide; bracts 6, similar in shape and size to those of staminate; rachis 6-13 cm long; rachillae 11-14, these 16-20 cm long, rigid, 1.5 mm diam. Flowers: Staminate in rather lax spirals, 3-3.5 x 2.5-3 mm, ± globose, dark when dried; calyx 1-1.5 mm x 2.5-3 mm, deeply lobed, sepals connate in basal 1/4, broadly rounded apically; petals 3 x 1.5-2 mm, valvate, connate apically and basally and adnate apically to pistillode and corolla opening by lateral slits, lanceolate, thick; stamens 2.5 mm high, filaments 1.75-2 mm long, anthers 2 mm long, dorsifixed, straight, oblong, white when fresh; pistillode 2.5-3 mm high, columnar, truncate. Pistillate in lax spirals, 2.5 x 3-3.5 mm, depressed-globose, dark when dried, superficial; calyx 1.5 x 2.5 mm, lobed, sepals imbricate in basal 1/2, broadly rounded apically; petals 2.5 x 22.5 mm, broadly ovate, imbricate, thick, acute and erect apically; pistil 2.2 mm high, ellipsoid, briefly 3-lobed apically. Fruits: 12 x 9-10 mm, subglobose, black, stigmatic residue basal; seeds 10 x 8 mm, subglobose, brown. (Hodel, D. 1992. Chamaedorea Palms, The Species and Their Cultivation.
