Discussion

Epiphyllum phyllanthus var. hookeri was recently reported by A. N. Lima (1996) from Estero Island, Lee County, Florida, growing on Sabal palmetto. The variety also occurs in the swamp at Fakahatchee Strand, Collier County, Florida. The population biology of this species, as well as its long-term persistence in the flora, need to be monitored. Details of its pollination biology are not known.
