Wow - fantastic photos - and welcome to Tropiscape. As Scott mentioned, habitat photos of mature palms are a real treat. Living in Thailand, I'm sure you have others, don't hesitate to share - and I'm sure Ed will use some on Palmpedia, with your permission?
Fantastic? I wonder if they grow real slow in situ like they do in my yard? Well, the slowest one I have might be mariae, actually. I'm not sure of the quality of the identification. I should just order some seed from RPS so I know what they are!
