This close relative of crinita has a northeastern and Appalachian range, and may be typical of more acid sites. Hybrids are reportedly rare and sterile (FNA 23; and citations there). Perigynia are ovoid-ellipsoid (versus obovoid); apices of pistillate scale are acuminate (versus retuse); and sheaths are scabrous (versus glabrous). Some colls. need rechecking or may appear intermediate.
