Description
Common Name: pine barren flatsedge
Cyperus retrorsus is a perennial graminoid. Most individuals are composed of 1-3 stems (FSU Herbarium).
Distribution
Ecology
Habitat
It requires wet summers and dry winters.[1]It can be found in pocosin communities[2], flatwoods communities[3], and longleaf pine communities[4].
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]
