Palm ID needed - Coccothrinax?

[Gunnar Hillert]

Aloha,

What palm species might this be? It seems to be a species of the genus Coccothrinax, is growing for many years in Maui, Hawaii in a fairly moist (mesic) climate. It is exposed to wind regularly.

I’m no expert in Coccothrinax, but I do have a bunch growing at the house.  Looks like Barbadensis to me.

If @Looking Glass is no expert on Coccothrinax  then I’m whatever is below that because I only have a couple in pots along with a bunch of seedlings. I am newly interested in the species though. That being said I believe some of the tell tale characteristics as I understand them are the color of the hastula, the stiffness and shape of the leaflets, how deeply divided they are, how complete of a circle that the leaflets form and the structure of the fibers. Of course the seeds can help to ID them as well. 
Someone here on Palmtalk shared this doc which has good info in it.

Iam throwing my money on cocthrinax Alta @Looking Glass the two are a synonym has it correct but I can’t see the hastula so barbadensis might be the one.

Depending on the resource, people still might go back and forth about Barbadensis and Alta being the same, or very slightly different.   All I know, is that ID’ing coccothrinax will drive you nuts!  

And the further away you get from Cuba and The Islands, the more mixed up and jumbled things get with all the hybrids sold as purebreds out there.   Palmpedia is a great resource, but every entry under coccothrinax has erroneous IDs/photos mixed in.   Probability wise, droopy fronted older randoms are usually heavy on the barbadensis/alta genes, and the very stiff older cardboard ones usually are miriguama descendants.  For the rarer ones, knowing your parent source has a direct line to Cuba is the best bet.   These guys hybridize like crazy.  And some of the hybrids are quite handsome.   

I always preferred the stiffer varieties, and liked Thrinax radiata as a smaller, droopy pinnate palm better than the droopier coccos.  But, we all have different tastes.  

Here’s just random photos of 5 different varieties in the yard, for fun…..

@Gunnar Hillert and @Looking Glass it looks like Cocothrinax barbadensis to me. Mine has set seeds and it’s a dead ringer for the palm in the OP.
