Additional Information at NatureServe

Diagnostic Characteristics:
Densely clumped sedge in the section Ovales , leaves thin, 1.5-3 mm wide and green without hyaline (white area) nearly to summit; inflorescence arched (not stiff) and spikes separated (not overlapping); perigynia very flat and thin, narrowly winged with a toothed beak half as long as the body, the scale short enough to expose at least the beak.

Avoid changes in moisture/hydrologic conditions at the site. Changes could result from overstory removal, stream/wetland alteration or impacts due to erosion.

Global Range:
Carex straminea occurs in widely separated populations throughout it range. It is known from Rhode Island, Connecticut, and New York south to North Carolina west to Missouri, Illinois, and Wisconsin (Mastrogiuseppe et al. 2002). Mackenzie (1931-1935) has a much larger range for C. straminea. This is because Mackenzie misapplied the name C. straminea to C. albolutescens and instead used the name C. richii for C. straminea (Mackenzie 1931-1935, Fernald 1970).
