The stilt palm ( Socratea ) constitute a genus within the family of Palm plants (Arecaceae). The five or so species are common in the Neotropics from Central to South America .
description
Vegetative characteristics
The trunks of the stilt palms are tall, gray, standing individually or rarely in groups (clusters). They are supported by an open cone of stilt-like, prickly, brown roots. The genus of the stilt palms can be recognized directly by the roots, in the other Iriarteeae genera the stilt roots are much closer together, so that the root cone is not transparent .
The leaf sheaths of the four to seven pinnate palm fronds form a distinct corolla. The leaflets , which are serrated at the tips, are segmented lengthways (with the exception of Socratea salazarii ). The segments separate and give the leaflets a clove-like appearance. The tips of the segments are often drooping, which is characteristic of some species.
Generative characteristics

- Socratea hecatonandra (Dugand) R.Bernal : The homeland is western Colombia and northwestern Ecuador.
- Socratea karstenii F.W. Stauffer & Balslev : The species first described in 2012 occurs in Venezuela.
