Corypha ID help needed

[Hilo Jason]

I bought this as “Corypha Sp”. Can anyone help me with an ID on it?  I’m wanting to know the species name so I can get an idea of how large it will be when mature. Not sure I have enough space for this or not in the new garden. 
 

 

thanks in advance

Good question!  I have a small Lecomtei and Umbraculifera, but had a similar question a few years ago.  If I had to guess it's a Lecomtei, just based on the pictures I took at Leu Gardens a couple of years ago.  Realistically they are all absolutely gigantic...so you'd need 20-30 feet of ground level clearance before they start going upwards.  Here's the pics I took:

As I understand it, Umbraculifera tends to keep a smaller number of leaflet divisions when young, where Utan and Lecomtei have bigger splits.

Here's my in-ground Corypha today, which is likely an Umbraculifera:

 

The color of the teeth might be the difference too...these are mostly "straw" colored.
