Ecology
Habitat
D. filiramum can be found pinelands ranging from dry to moist soils.[2] A specimen collected from the Apalachicola National Forest in the Florida panhandle found the species frequent in an open area of cutover pine flatwoods that was near a trail in wet loamy sand.[3]
Phenology
This species generally flowers from May until October.[2] This species was observed fruiting in May.[3]
Pollination and use by animals
