Description Plantae 45—60 cm altae; rhizomata repentia nulla. Radices pilis brevibus griseolis tectae. Culmi scabri, basi vaginis rubeolo-fuscis vel purpureis, splendentibus, brevibus (2—3 cm lg.) praediti. Folia fructificatione culmis sesqui-duplo breviora, rarius eis subaequilonga, 1—2.5(3) mm It., plana, marginibus involuta, subtus papillis obtecta. Inflorescentia communis (1.2)2—4(4.2) cm lg., spiculis in numero 3—4, distantibus. Bractea infima cum lamina angusta evoluta, inflorescentia paulo brevior, sina vagina, bractea secunda setacea. Spicula terminalis staminata (1) , oblongo clavata, 0.9—1.2 cm Ig., 1.1—1.3 mm I, stipitata, stipite 0.6—0.8 cm Ig., brunnea vel fusca, squamis pallide-fuscidulo-fermugineis, acutis, frequenter cum mucrone. Prope basin spicula estaminatae flores solitarios femineos vulgo habens. Spiculae pistillatae in numero 1—2, ovoideae vel oblongo ovoideae, (0.3)0.7—1(1.1) cm Ig., 0.3—0.4 cm lt., pauciflorae, laxiflorae, (1)2.5—3.5 cm lg. distantes, sessiles, inferior interdum stipitata stipite brevit; squamae vulgo utriculis breviores et angustiores, atrofuscae vel brunneae cum dorso diluto, acutae, saepe cum mucrone.
