Description
Distribution
Euphorbia discoidalis is distributed from eastern and central Georgia south and west to the Florida panhandle and eastern Texas.[1]
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.[2] Euphorbia discoidalis is restricted to native groundcover with a statistical affinity in upland pinelands of South Georgia.[3] Populations appear to increase due to disturbance.[4]
Associated species include longleaf pine, slash pine, shortleaf pine, oaks, red oak, mockernut hickory, magnolia.[2]
Phenology
It flowers from late August to frost.[4] This species has been observed flowering in August and September.[2]
Fire ecology
This species is found in areas that are burned annually such as longleaf pine-wiregrass savannas and sandhills.[2] 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]
