Description Rhizome short. Culms densely tufted, 13-16 cm tall, less than 1 mm thick, filiform, triquetrous. Leaves shorter than or equaling culm, linear, revolute on margins, blades 1-1.5 mm wide, soft, sheaths dark brown, persistent. Involucral bracts leaflike, shorter than inflorescence, long sheathed.
