Inflorescences infrafoliar, one per node, to 80 cm long, once branched; male inflorescences with 3-25 pendulous branches; female inflorescences with 2-15, horizontal to erect branches, orange in fruit. Male flowers with petals united at apex. Fruits black, about 9 x 11 mm. (Borchsenius, F. 1998)/Palmweb. Editing by edric.
The species is variable, especially in leaf size, number and size of pinnae, and size and ramification of the inflorescence. It is defined by having male flowers with petals fused at their apex, but variation in vegetative characters within the species is not fully understood. Simple-leaved forms are sometimes found occurring together with the common, pinnate-leaved form, e.g., around Plan de Milagro in the Morona-Santiago province. (Borchsenius, F. 1998)/Palmweb.
Requirements: Full shade to filtered light, this is an understory palm. Consistently moist soil, well drained position. Often planted in groupings.
Comments and Curiosities
Chamaedorea are dioecious, male, and female flowers, on separate plants.
Uses: The petioles are chewed by the Mayna Jivaros to blacken teeth, starting at an age of five or six years. (Schultes, R.E., and R.F. Raffauf. 1990)/Palmweb.
Chamaedorea pinnatifrons plants are removed from the forest by campesinos and sold in street-side markets in some cities. (Bernal, R. 1998)/Palmweb.
The basal part of the stem with its numerous adventitious roots has been used by the local population for whipping food; thus the local name, wich means " little mill." (Svenning, J.C., and H. Balslev. 1998)/Palmweb.
