SLENDER SAND SEDGE
C. filiculmis of Michigan Flora.
Usually in dry sandy open ground, including oak or jack pine savannas, roadsides, old fields, dunes, and dry prairies; occasionally in moister places on banks of lakes and ponds. A fairly distinctive species, and one of our commonest. Most Michigan collections are subsp. macilentus (Fernald) Marcks, with the scales ca. 1.9–2.6 mm long, but a scattering of specimens from the southern half of the Lower Peninsula are the coarser subsp. lupulinus with scales mostly 2.5–3.4 mm long (in Michigan specimens). A few specimens appear transitional.
