Florida Keys History and Distribution:
Not reported for the Florida Keys by John Kunkel Small in 1913. This hybrid (P. glaucescens x P. prostrata) was collected only once in 1995 by George D. Gann and Keith A. Bradley (151, FTG) at Dagny Johnson Key Largo Hammocks Botancal State Park in an area that has since been highly modified as part of an ecological restoration project.
