Description
A description of Cyperus retrorsus is provided in The Flora of North America. Cyperus retrorsus is a perennial graminoid. Most individuals are composed of 1-3 stems (FSU Herbarium).
Distribution
Ecology
Habitat
C. retrorsus requires wet summers and dry winters.[1] It also prefers higher light levels associated with open or semi-shaded conditions, and moist to wet sandy soils (FSU Herbarium). It has been observed growing in a variety of related soil types, including wet sand, moist sandy peat, moist loamy sand, drying sandy soil, drying loam, peat, and dry sterile sand (FSU Herbarium).
As such, this species can be found in or near wet habitat like pocosin communities[2], lake shores, phosphate pools, marshes, lakeside sinkhole berms, drained bogs, river floodplains, seepage streams, and drying wetland depressions (FSU Herbarium). However, it also can be found in drier areas, including flatwoods communities[3], and longleaf pine communities[4]. Additionally, it has been found in oak-hickory forests, grassy areas on islands, turkey oak sand ridges, sandhills, live oak hammocks, dried lake bottoms, pine flatwoods-savannas, old stabilized sand dunes, prairies, open scrub, and scrub barrens (FSU Herbarium).
Along with being found in natural community types, C. retrorsus has been found in disturbed habitat such as cleared floodplains, roadside ditches, railways, trail edges, clear-cuts, fallow fields, borrow pits, dredge spoils, former pine plantations, orange groves, longleaf pine restoration sites, and disturbed sandhill communities (FSU Herbarium).\
Associated species include Paspalum notatum, Eupatorium mohrii, Rubus cuneifolius, Ludwigia maritima, Pityopsis, Solidago fistulosa, Aletris lutea, Eleusine, Dactyloctenium, Digitaria, Panicum, Rhynchospora fernaldii, R. fasicularis, Andropogon, Scleria reticularis, Trilisa, Liatris, Aristida, Andropogon, Bulbostylis, Clitoria, Juncus, Pteridium aquilinum, Cyperus filiculmis, Commelina erecta, Serenoa repens, Sagittaria graminea, Woodwardia virginica, Nyssa biflora, Acer rubrum, Liquidambar styraciflua, Rynchospora fernaldii, R. fascicularis, Carex longii, madien cane, and others (FSU Herbarium).
Phenology
Flowering has been observed in July through October (FSU Herbarium).
Seed dispersal
Seed bank and germination
It accounted for 29% of a late-summer Virginia pocosin seed bank.[2]
Fire ecology
C. cyperus has been found in burned areas including recently burned slash pine-scrub flat, annually burned savanna, and frequently burned mature longleaf pine-wiregrass communities, indicating a level of fire tolerance (FSU Herbarium).
It responds best to a moderate-severity level burn. Recovery after fire is achieved by resprouting and seed.[1] Abundance was found to significantly decrease over 25 years after fire in a scrubby flatwoods, suggesting the significance of fire in its life history.[5]
