Taxonomic notes
Synonyms: Asimina longifolia Kral var. longifolia; Pityothamnus angustifolius (Rafinesque) Small[1]
Varieties: none[1]
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, roadsides, 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. It was found to decrease its occurrence or become absent in respnse to soil disturbance by agricultural practices in southwest Georgia. It has also shown resistance to regrowth in reestablished pinelands that were disturbed by agriculture.[4]
Associated species includes Phlox floridana, Stillingia sylvatica, Lactuca graminifolia, Stylosanthes biflora, Erigeron strigosa, Baptisia lanceolata, Hedyotis crassifolia, Pterocauloon undulatum, Asclepias humistrata, Quercus hemisphaerica and others.[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] and resprouts and flowers within two months of burning. KMR Populations of Asimina angustifolia have been known to persist through repeated annual burns.[7]
Herbivory and toxicology
It consists of 2-5% of diet for small mammals and terrestrial birds.[8] For humans, the fruit is edible, like a cucumber, with a fine hard pulp that is yellow inside.[9] The plant also serves as a host for the Zebra Swallowtail Butterfly, and it is seasonally consumed by gopher tortoises.[10]
Diseases and parasites
Susceptible to leaf blotch, eye spot, and other fungal diseases.[11]
Conservation, cultivation, and restoration
A. angustifolia should avoid soil disturbance by agriculture to conserve its presence in pine communities.[4] It requires frequent fire and protection from soil disturbance.
Cultural use
The fruit of A. triloba is known to be sweet and custard-like. It was often used in baking, pie filling, or eaten raw. The fruits fall from the tree early and must be harvested from the ground to ripen later.[12] For medicinal purposes, the seeds can be used to induce vomiting or to treat head lice when powdered, and the fruit juice can be a treatment for intestinal worms.[13] Caution should be exercised though, as some people exhibit an allergic reaction of dermatitis to the fruit.[14]
