Discussion
Pseudophoenix sargentii occupies a most precarious position in the North American flora: only small populations remain on Elliott Key in southern Florida (B. R. Ledin et al. 1959; C. Lippincott 1992, 1995). Since its discovery some 100 years ago, botanists have witnessed a precipitous decline in Pseudophoenix populations in the Florida Keys as these attractive palms were removed for use in landscaping (F. C. Craighead Sr. and D. B. Ward n.d.). Recently naturalists have replanted palms on Long Key, more than 30 years after the last wild palms had been seen there (C. Lippincott 1992, 1995).
Pseudophoenix is probably insect pollinated, since its greenish yellow flowers produce nectar and attract numerous bees. The fruits of P. sargentii, which float when dry, are thought to be dispersed by water (R. W. Read 1968); their attractive red coloration and fleshy mesocarp, however, suggest animal dispersal (S. Zona and A. Henderson 1989).
