Folia linearia, 1.5-3.0 dm longa, erecta vel leviter expansa, subdisticha, vaginis scaporum longiora. Laminae vaginis 5-10-plo longiores, 1-2 mm latae, planae, rectae, longitudine pauci-pluri-costatae et sulcatae, a basi ad medium compressae, apicem versus teretes vel subteretes, apices contracti, angusti rotundati, incrassati, persaepe canaliculati, margines integri, non incrassati; vaginae carinatae, pallide lamprobrunneolae, pluricostatae, praeter costas scariosae, marginibus in laminas gradatim convergentibus, ad apicem ligulam scariosam curtam latam fascientibus, infime gradatim expansae, acies integrae. Vaginae scaporum laxae, tortae, multicostatae, ad apicem dilatatae; laminae breves, rectae. Scapi graciles, teretes, recti vel aliquantum flexuosi, 2.5-3.5 dm alti, 0.50.6 mm crassi, olivacei vel rubelli. Spicae pluriflorae, ellipticae, 5-6 mm longae, acutae, bracteae subdecussatae, naviculares vel convexae, ecarinatae sed mediane 1-nervosae, scariosae, ferrugineae, erosae; bracteae steriles 4, pari infimo oblongo saltem medium spicae aequans, pari intimo ovato ca. 3 mm longo; bracteae fertiles ovatae usque ad 4 mm longae; area dorsali lanceolata, ferruginea vel brunneola, bractearum dimidium vel totum aequans. Sepala lateralia lanceolata, valde inequilatera, ca. 4 mm longa, acuta; ala carinali angusta sed fortes, integra. Laminae petalorum late obovatae, 2.53.0 mm longae, late rotundatae, valde erosae, cuneatae, luteolae. Staminodia bibrachiata, brachiis longipenicellatis.
