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?
There are already plenty of my pictures on Palmpedia... (Copyright Philippe Alvarez or Pilou) You can see my palms collection there : www.palmiers.eu
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!
