Description
Distribution
Ecology
Habitat
Habitats of E. discoidalis include pine dominated habitats such as longleaf pine scrubs, sandhills, upland pine, and drained uplands. It prefers areas that have high light level/ open canopies. It also occurs in disturbed habitats such as fallow fields, clearings, and in annually burned pinelands. It likes sandy soil types.[1] Euphorbia discoidalis is restricted to native groundcover with a statistical affinity in upland pinelands of South Georgia.[2] Populations appear to increase due to disturbance.[3]
Associated species include longleaf pine, slash pine, shortleaf pine, oaks, red oak, mockernut hickory, magnolia.[1]
Phenology
It flowers from late August to frost.[4] This species has been observed flowering in August and September.[1]
Fire ecology
This species is found in areas that are burned annually such as longleaf pine-wiregrass savannas and sandhills.[1] It responds positively to fire. Kral (1983) writes "In naturally stocked uplands it increases as a result of woods fires which reduce competing woody vegetation." [4]
