Description
A description of Cyperus plukenetii is provided in The Flora of North America. Cyperus plukenetii is a perennial graminoid. Individual plants have numerous stems, each with a cormose base; and the bases are tightly bunched together (FSU Herbarium).
Distribution
Ecology
Habitat
C. plukenetii requires sandy soils.[1] It also prefers higher light levels, from open to semi-open conditions (FSU Herbarium). It is found in sparse scrub woods, woods' edges, and open fields.[2] Other habitat types include dry pine and oak lands, scrub oak sandhills, turkey oak-longleaf pine barrens, open hardwood stands, open upland pine forests, and river banks, but it is infrequent in open stands of longleaf pine and wiregrass (FSU Herbarium). It also has been found in disturbed areas, including bulldozed scrub oak sandhills, cut-over longleaf pine-turkey oak sand ridges and flatwoods, pasture fence lines, young pine plantations, and roadsides (FSU Herbarium).
Associated species include Liatris, Agalinis, Chrysopsis, Aristida stricta, Phoebanthus tenuifolias, Eupatorium album, Pteridium aquilinum var. pseudacaidatum, Serenoa repens, Quercus margaretta, Q. minima, Q. ellottii (FSU Herbarium).
Seed dispersal
It can be dispersed in a variety of ways: rain wash, transport of achenes in mud on feet of migratory waterfowl[3], ingestion of fruits by migratory waterfowl[4], and flotation of achenes (Chermezon 1924; Ridley 1930; Lye 1981)[5]It also uses animals as dispersal agents by attaching to their fur by spikelets[1] According to Kay Kirkman, a plant ecologist, this species disperses by gravity.

Fire ecology
This species is fire tolerant and has been found on annually burned pinelands (FSU Herbarium).
