Flora of Virginia Name/Status
Cyperus lupulinus (Sprengel) Marcks ssp. lupulinus
Map is very incomplete at present, as only a few specimens of Cyperus lupulinus have been determined to subspecies. In addition, this species has generally been lumped with Cyperus filiculmis and its subspecies not recognized in Virginia studies. See also map of the Cyperus lupulinus complex, which includes all records for both ssp. and Cyperus filiculmis. Extensive field and herbarium work will be necessary to determine the status of each subspecies and map them separately.
The species occurs in dry, rocky woodlands, barrens, and outcrops on mafic, granitic, and felsic sedimentary and metasedimentary rocks; dry sandy or clay soil of fields, pastures, and clearings. Currently, the distribution and status of ssp. lupulinus are incompletely known, but it appears to be locally frequent in all parts of the state, except perhaps sandhill areas of se. Virginia.
