half to three feet long, pale yellow-green, an inch and a half

Dry coral ridges from the shores of Bay Biscayne, where it 
is rare, along many of the southern keys to the Marquesas group, 
west of Key West. Discovered by A. H. Curtiss in 1880. Very 
similar to Thrinax argentea R. & S., the seeds differing, however, 
from those of that species as named in the herbarium of the 
Royal Gardens, Kew, in their brown, not mahogany-red, color 
and larger size. i

shores of Bay Biscayne, and possibly only a depauperate form 
of the last. :
