Is it Chambeyronia macrocarpa (green form) or sp. houailou? And I've never seen a new red leaf from this tree.

Could you help identify? All photos were taken in different months. But they are from the same tree. Thank you.

Caveat: I am not an expert. That doesn't look like C. houailou to me. I would expect more recurve in the leaves and more of a V-arrangement of the leaflets, which should also look thicker and heavier than the palm in your photos exhibits. I'm not even sure this is Chambeyronia, though it does have the look of a New Caledonia palm. (I can't explain that.) When I compare the trunk to those in my garden, the leaf rings seem too close together, yet the leaves seem to match. Is this growing in a dry area?

Thank you for your information.  This is growing near stream in Northern of Thailand . It is in tropical rainforest area.

Does this rain forest have a dry season and a wet season? Are there other palms of this species nearby? Does it seem likely that it was planted or seed arrived via the stream?  

Just for comparison of the trunk, I'm adding a photo of my Chambeyronia grove which are half macrocarpa and half var. 'hookeri.' You can see what I mean about the leaf scars. These are grown in an area with 150 inches of rain per year with no extended dry season.

Definitely C macrocarpa. I’m pretty sure I see var macrocarpa and var hookeri in these pics.

Chambeyronia macrocarpa is a variable species and depending on your location in New Caledonia can have varying features. Some never get red new leaves. Some have more of a recurve to the leaves, some with thinner leaflets, others that have wider leaflets. Some are dark green in the crownshaft, others even have a slight bluish tinge, and in one forest you may see these slight variations between individuals. 

I think the palm in question is a green form macrocarpa.

What about cyphophoenix elegans?

Thank you.  However I don't think it is because the seeds are different.

Answer your question.  Yes, we have dry and wet season. In my garden have MC green form, Hookeri, Watermelon and houailou. It was planted.

The dry season would explain the closer leaf scars perhaps. I agree with Tyrone's conclusion, green form.
