Description
See NRCS Plants Database Common Name: oblongleaf snakeherb
Distribution
The Florida distribution is provided by the Atlas of Florida Vascular Plants.
Ecology
Indicator of longleaf pine woodlands; not found on pasture or cultivated lands.[1]
Habitat
D. oblongifolia appears to be restricted to soils with a sandy A horizon, whether in Entisols (sandhills) or Ultisols (clayhills) (KMR,[2]). Native undisturbed longleaf pine assosciate; found in burned and unburned areas.[3] Resides in upland and lowland areas old growth longleaf pine/wiregrass sandhill habitat.[4] A common forb in a fire-maintanied forest structure that is savanna-like with an open canopy of P. palustris.[5] It is found in pineland.[6] It is abundant in longleaf pine communities.[7] Resides in upland, midslope, and lowland areas old growth longleaf pine/wiregrass sandhill habitat.[4]. Dyschoriste oblongifolia is restricted to native groundcover with a statistical affinity in upland pinelands of South Georgia.[2]. This species also has been observed in scrub environments, turkey oak barrens, wiregrass-palmetto flatwoods, mixed hardwood forests, mixed pine-hardwoods, and slopes and ridges of longleaf pine forests (FSU Herbarium) It has also been seen growing in human disturbed areas such as recently cleared pine forests, ruderal edges of sandhills, roadsides, plowed areas, bulldozed areas, and open fields (FSU Herbarium). D. oblongifolia can grow in both full light and semi shaded environments in deep, loose, and/or loamy sands along ridges and generally flat areas (FSU Herbarium).
Phenology
D. oblongifolia germinates and flowers within a few weeks following fire at a wide range of burn dates, at least from March to July (KMR).
Seed dispersal
By ants.[3]
Seed bank and germination
Fire ecology
It resprouts after fire.[7] It flowers within two months of burning in the spring.KMRExtremely vulnerable to disturbance.[8] Was observed to resprout one month after a fire in July of 1993.[9].
Pollination
Use by animals
Diseases and parasites
Conservation and management
Cultivation and restoration
