Description
A description of Asimina angustifolia is provided in The Flora of North America.
Distribution
It is found in southeastern Georgia to central peninsular of Florida to the west towards the Suwannee River (Weakley 2015).
Ecology
Habitat
Growing in what was previously upland sandhill longleaf pine- wiregrass ecosystem. [1] In Heuberger’s study, they observed Asiminia angustifolia in burned and in unburned patches. Frequently burned longleaf pine-wiregrass uplands (Ultisols) and longleaf wiregrass sandhills (Entisols) in north Florida and southern Georgia. Asimina angustifolia is predominately in the native groundcover with a statistical affinity in upland pinelands of South Georgia (Ostertag and Robertson 2007). It is found in dry, well drained pinelands (Weakley 2015) and sandhills, flatwoods, and scrub habitats in partial shade (Wunderlin and Hansen 2011, FSU Herbarium). This species has also been found to be growing along roadsides (FSU Herbarium).
Associated species includes Phlox floridana, Stillingia sylvatica, Lactuca graminifolia, Stylosanthes biflora, Erigeron strigosa, Baptisia lanceolata, Hedyotis crassifolia, Pterocauloon undulatum, Asclepias humistrata, Quercus hemisphaerica and other (FSU Herbarium).
Phenology
It flowers from spring to summer (Wunderlin and Hansen 2011).
Kevin Robertson has observed this species flower within three months of burning. KMR
Fire ecology
This species has been seen in burned and fire excluded areas (FSU Herbarium). Resprouts and flowers within two months of burning. KMR
Conservation and Management
It requires frequent fire and protection from soil disturbance.
