Florida Keys History and Distribution: Reported in 1913 by John Kunkel Small for hammocks and sandy places on the island of Key West (as C. blodgettii - the type locality) and for hammocks on Long Key (as C. litoreus - the type locality).  We consider this native to the middle Keys and lower Keys, but possibly extirpated in the middle Keys.
