South Florida History and Distribution: Ranked as critically imperiled in Rare Plants of South Florida (
Gann et al. 2002; pp 404-406) based on three occurrences in two protected areas and one non-protected area. This species is now known from eight protected areas and was reranked as imperiled using updated NatureServe criteria.

Comments: Although ranked as critically imperliled by IRC in Rare Plants of South Florida (Gann, Bradley and Woodmansee 2002), a number of new populations have been discovered since 2002 and additional herbarium specimens have become available leading to the downranking of this to imperiled in 2014.  Updated NatureServe criteria were used.

          Florida Keys History and Distribution: First collected between 1838 and 1853 by John Loomis Blodgett on the island of Key West.  Reported in 
1913  by John Kunkel Small for open hammocks and sandy places on the island of Key West.  Recently disovered by George D. Gann on Stock Island adjacent to the island of Key West.  Also recently discovered on Lignumvitae Key.  We consider this native and extant in the middle Keys and lower Keys.  For more information on C. floridanus in South Florida, see IRC's 
species account.
