Description

"Tall, usually solitary palm (sometimes suckering and sometimes trunkless) from South America - very spiny palm! Very long leaves up to 20' with white undersides- striking. But everything is spiny on this palm-even the seeds and flowers." (Geoff Stein).

A large, highly variable species that can be short and stemless thru to a tall, robust, clustering palm. It has an open conical shaped crown with large, flat leaves, and closely spaced leaflets, with dark green uppers, and silvery undersides. The large fruits are edible, and the seed kernel is a significant source of edible oil in Brazil, where it is gathered commercially. The kernel also produces a very rich extract which is used by the beauty industry for shampoos, conditioners, and moisturizing skin care products, The leaf fibers used locally for hammocks.

Caespitose palms; infructescence often pendulous; fruit up to 9 cm long, 4,5 cm broad; mesocarp very fleshy when ripe, 6—10 mm thick; corolla of the pistillate flower vase-shaped, or tubular often shallowly contracted at the middle or at the distal third (like a 8), large enough to encompass the proximal part of the stigmas.
