CYPERACEAE

Cyperus granitophilus McVaugh. Granite Flatsedge. Phen: Jul-Oct. Hab: Granitic flatrocks, rarely on diabase flatrocks of the Piedmont, Altamaha Grit glades of the Coastal Plain, and sandstone outcrops of the Cumberland Plateau. Dist: Sc. VA south to ec. AL in the Piedmont; disjunct in se. and c. TN on sandstone and limestone and in sc. GA on Altamaha Grit; disjunct in c. TX and s. OK (O'Kennon & Taylor 2015). Plants reported as C. granitophilus by O'Kennon & Taylor (2015) are more closely related to C. squarrosus and are better treated as C. squarrosus var. runyonii (R. Carter, pers.comm., 2022).
