Carex richardsonii B. S. Slaughter

Very local, flourishing for only a few days in spring or early summer. Sandy open ground, bluffs, borders of oak forests, openings among cedars over limestone rock.

This species is sometimes misidentified as Carex pensuylvanica, and indeed is somewhat similar in overall appearance to C. pensylvanica (and C. lucorum).  It is easily distinguished by the definitely sheathing, purple tinted lower bracts, and the short pedunculate, and more elongate pistillate spikes.
