Description
Common Name: Slimleaf Pawpaw
Synonym names: A. longifolia Kral var. longifolia; Pityothamnus angustifolius (Raf.) Small
Distribution
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 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). Found in dry, well drained pinelands (Weakley 2015) and sandhills, flatwoods, and scrub habitats (Wunderlin and Hansen 2011, FSU Herbarium).
Phenology
Flowers from spring to summer (Wunderlin and Hansen 2011).
Seed dispersal
Seed bank and germination
Fire ecology
Resprouts and flowers within two months of burning. KMR
Pollination
Use by animals
Diseases and parasites
Conservation and Management
Requires frequent fire and protection from soil disturbance.
Cultivation and restoration
