Description
Common Name: Slender scratchdaisy
Distribution
U.S. Gulf States. Sandy soil where pocket gophers occur which gives the area the characteristic disturbed appearance, “with bare and freshly turned patches of soil”[1] It is found occasionally in disturbed areas as defined in - Analysis of Longleaf Pine Sandhill Vegetation in Northwest Florida - in the bluestem-dominant plots.[2]
Ecology
Pine thinning resulted in significantly higher frequencies of C. divaricatum after 5 and 8 years.[3]
Habitat
Occurs in Sandhill Research and Education Center in South Carolina where soil series include Lakeland sands, loamy sands. Are mostly entisols (arenic and grosarenic quartzipsamments) with high permeability and low available water capacity. Previously was an agricultural area, so some of the land includes mosaic old-fields, pine stands, scrub oak dominated forests, and forested wetlands.[4] Found in open areas near the edges of mixed pine-hardwood forests and wetlands, at boundaries between or near 2 or more natural communities in Alachua County, Florida.[5] It is found in longleaf pine savanna communities.[3] Is found in Longleaf pine-wiregrass savannas, turkey oak sand ridges, and edges of hardwood swamps and hillside bogs. Is also found in human disturbed areas, such as roadsides, fallow fields, and orange groves. Requires high light levels. Is associated in areas with sandy loam, clayey soil, and sandy soil types (FSU Herbarium).
Phenology
Summer annual.[1] Has been observed fruiting in October and November (FSU Herbarium).
