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.[1]

Ecology

Habitat

Habitats include dry, well drained pinelands[1] and sandhills, flatwoods, and scrub habitats in partial shade.[2][3] Specifically it is found in 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.[4] This species has also been found to be growing along roadsides.[3]

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.[3]

Phenology

A. angustifolia flowers from spring to summer and has been observed to flower in January and May to July in north Florida.[2][5]

Kevin Robertson has observed this species flower within three months of burning. KMR

Seed dispersal

This species is thought to be dispersed by consumption by vertebrates. [6]

Fire ecology

This species has been seen in burned and fire excluded areas[3]. Resprouts and flowers within two months of burning. KMR

Diseases and parasites

Susceptible to leaf blotch, eye spot, and other fungal diseases.[7]

Conservation and management

It requires frequent fire and protection from soil disturbance.
