A description of Cyperus filiculmis is provided in The Flora of North America.




Cyperus filiculmis is found mainly in sandy soils, both wet and dry, including drying loamy sand, coarse sand, and moist sandy-peaty soil. It prefers sunny, open sites, and occurs in longleaf pine-wiregrass flatwoods and longleaf pine-turkey oak sand ridges. C. filiculumis is seen in disturbed habitats such as power line corridors, clear-cuts, and bulldozed or logged sites.[1]

Associated species includes Pinus palustris, Quercus laevis, and Aristidia stricta.[1]


C. filiculmis has been observed both flowering and fruiting in May through November with peak inflorescence in June and August.[2][1]

Seed dispersal

This species is thought to be dispersed by gravity.[3]

Fire ecology

This species is fire tolerant, and has been observed in recently burned pine flatwoods.[1]
