I'm hoping someone can help to identify this wild palm/palmetto growing in the woods in Wilmington, NC.  Most of the two dozen specimens are in a roughly 200-foot radius within a larger area of pines and small hardwoods.  The forest floor is a deep, undisturbed mat of pine needles, and the immediate area has had little direct human disturbance for at least 10-15 years.
 
 
The tallest plants have a woody trunk 18 inches tall and maybe 1.5 inches in diameter.  A striking characteristic is some of the leaves have curly fibrous edges.
 
 
Thanks for any ideas you may have!
