Description
Distribution
Ecology
Habitat
Occurs in the Kansas-Nebraska Drift Loess Hills characterized by divides with moderately steep slopes with silt loams and silty clay loams occasionally broken by bedrock outcrops (Watt et al. 1967). Digitaria filiformis was vouchered on an outcrop habitat on Panola Mountain located within Henry-Rockdale county line, southeast of Atlanta, Georgia (Bostick 1971). Digitaria filiformis has been found occasionally in mesic flatwoods in Hillsborough County, Florida (Myers et al. 2003). It has been described as occuring on “upland, sandhill areas on droughty, infertile entisols and ultisols with loamy sand to sandy loam surface horizons” (Archer et al. 2007).
Phenology
Flowering and fruiting have been observed in June, August, September, October and November (FSU Herbarium).
Seed dispersal
Seed bank and germination
Fire ecology
This species has been found in habitat types that are maintained by fire, which implies some level of fire tolerance (FSU Herbarium).
Pollination
Use by animals
White-tailed deer stomach contents, in Kansas-Nebraska Drift Loess Hills, included Digitaria filiformis year-round (Watt et al. 1967).
Diseases and parasites
Conservation and Management
Cultivation and restoration
