Taxonomic notes
The genus Palafoxia is named after Jose de Palafox y Melci a spanish captian-general, well known in the Peninsular War. The species is named for William T. Feay, who was an avid plant collector in the southeast[1].
Description
A description of Palafoxia feayi is provided in The Flora of North America.
Distribution
P. feayi is endemic to the southern two thirds of the Florida peninsula[1].
Ecology
Habitat
P. feayi is restricted to the well drained sandy uplands of the southern two-thirds of the Florida peninsula [1]. Habitats include oak-palmetto-Lyonia scrubs, sand pine scrubs, and pine/palmetto scrubs. It has also been observed growing with Bigelowia nuttallii in sandbur-natal grass in an open sand pine remnant. Associated species include Bigelowia nuttallii, Serenoa repens, Pinus clausa, natalgrass, sandbur, and oak species (FSU Herbarium).
Phenology
Flowers July through December (FSU Herbarium).
Seed dispersal
Seed bank and germination
Fire ecology
It has been observed growing in a burned scrub (FSU Herbarium).
Fire is important for maintaining the scrub habitat and occurs intervals ranging 10-100 years, depending on the specific scrub. Above ground P. feayi individuals are killed by fire, however it quickly resprouts after fire This species has adapted to fire by establishing seedlings between fires and resprouting postfire from the root system. Reproduction peaks during the first year post-fire and sharply declines after the first year (Ostertag and Menges 1994). Conrad and Segaves (2012) found a strong decrease in AMF colonization with time since fire, however, they propose that this is the result of an ephermal nutrient pulse associated with scrub fires and changes in light availability. On the contrary to these findings, Anderson and Menges (1997) did not find a change in mycorrhizal colonization associated with fire.
