Would anyone be able to identify from this photo? It's the only one I have of what the Lacandon (Maya) call "miis". They say it's like Chamaedorea ernesti-augustii but with longer leaves. Apparently they don't use it for thatch. Looks perfect for that (to me at least.)
This photo was taken in the rainforest of Chiapas, MX at 825 m elevation.
