Growing in rain forest, south east Chiapas, MX, at approx. 825 m elevation. Leaves used for roof thatch. The people say it has red fruits, and reddish growing tip (?). It grows in the "hills" (not in inundated, flat land). The bifid leaves and thecorrogated appearance of the blades suggest to me it is a geonoma. Apparently only G. interrupta grows in the area (Henderson et. al. 1995). Anbd this species shown here doesn't resemble G. interrupta. So I was wondering what else it could--a kind of Chamaedorea? Something else?
When palms are young and growing in a shaded place they can appear quite different to the adults. I don't have access to much information on Geonoma but from the photos I've seen Geonoma interrupta would be a good possibility. If you want to find out for definite try the IPS website (www.palmtalk.org/forum/), someone there will be able to give you an answer straight away.
