Description
R. alifanus is a perennial forb/herb of the Melastomataceae family that is native to North America.[1]
Distribution
R. alifanus is found in the southeastern United States; specifically in Florida, Georgia, South Carolina, North Carolina, Alabama, Louisiana, Mississippi, and Texas.[1]
Ecology
Habitat
R. alifanus is typically found in pine flatwoods, savannas, longleaf pine-scrub oak ridges, pine woodlands, hillside bogs, cypress ponds, and pocosin borders.[2][3] It is also found in disturbed areas including road banks, drained and bulldozed flatwoods bogs, logged pinelands, and burned longleaf pine savanna.[3] Transitions between uplands and lowlands, commonly wet prairie, is another common habitat to find R. alifanus.[4]
Associated species: Pinus palustris, Muhlenbergia capillaris, Paspalum plicatulum, Xyris spp., Pluchea rosea, Rhexia lutea, Liatris spp., Dichanthelium spp., and Asclepias.[5]
R. alifanus was unaffected by clearcutting and chopping in north Florida flatwoods forests.[6]
Rhexia alifanus is frequent and abundant in the Upper Panhandle Savannas and Panhandle Seepage Savannas community type. It is an indicator species for the Lower Panhandle Savannas community type as described in Carr et al. (2010).[7]
Phenology
R. alifanus has been observed flowering May through July.[8]
Seed dispersal
This species is thought to be dispersed by gravity.[9]
Fire ecology
Populations of Rhexia alifanus have been known to persist through repeated annual burning.[10]
Pollination and use by animals
Bees are pollinators for R. alifanus.[11]
Conservation, cultivation, and restoration
Cultural use
It is possible the greens and tubers can be used in salads for a sweetish, nutty taste.[12]
