Plants with glabrous leaves and sheaths are occasionally found and have been treated as Carex oxylepis forma glabra Kükenthal; plants with perigynia pubescent, in addition to normally pilose leaves and sheaths, have been treated as C. oxylepis var. pubescens. Taxonomic recognition is not warranted in either case because the traits vary within populations and are not correlated with other structural differences.
