Diagnosis Specie insigne intermedia tra le sezioni Paludosa e Vesicaria si accosta alla prima per gli otricoli maturi coriacei e per la forma delle squame maschili; io invece la colloco nella seconda per gli stili fortemente ginocchiati alla base e per l'otricolo bruscamente contratto in rostro cilindrico e lungo. Del resto è distintissima da tutte le specie note di queste due sezioni.[A species intermediate between the Paludosae and Vesicariae sections, it resembles the former in its mature leathery perigynia and the shape of the staminate scales; however, I place it in the latter section due to its styles strongly geniculate at the base and its perigynia abruptly contracted into a long, cylindrical beak. Moreover, it is quite distinct from all known species in these two sections.] [details]
Original description Rhizoma stoloniferum, subcaespitosum; stolones abbreviati robusti. Caules (inflorescentia non computata) circ. 50 cm. alti, basi foliosi, acute, triquetri, sub inflorescentia omnino laeves. Folia culmum aequantes, 4-8 mm. lata parce septato-nodosa, striato-nervosa. Axis inflorescentiae acute triquetra dense in angulis serrulato-hispidula, scaberrima; internodio inferiore 3,5-4,5 cm. longo, caeteri valde abbreviati, bracteae breviter (1-4 cm.) vaginatae lineares. Inflorescentia abbreviata densa e spicis 4-6, erectis, pedunculis 5-12 mm. longis cylindraceis, foemineis 4-7 mm. longis, 8-10 mm. crassis, purpurascentibus; masculis semper solitariis 3-5 cm. longis, 5-6 mm. latis purpureo et viride variegatis. Squamae foeminae atropurpureae in dorso angustissime virides, 3 mm. longae, 1 mm. latae, anguste ellipticae abrupte in cuspidem contracta 1-2 mm. longam. Utriculi squamas (cuspide comprehensa), aequantes vel superantes, 3-4 mm. longi, horizontaliter patentes, densissimi, in axi subverticillate inserti, ovati apice abrupte in rostrum 1 mm. longum subcylidraceum apice breviter bicuspidatum, cuspidibus parum divaricatis laevibus, basi in stipitem 0,5-1 mm. longum angustati nitidi, longitudinaliter crebre et crassicuscule nervosi anguste vesciculosi e coriacei, virides sed ad apicem et in rostro purpurei. Achenium obovatum, acute triquetrum minute rugosum, fusce flavum, apice rotundatum in stilum basi eximie flexuosum, decurrens, 1,2 mm. longum, 0,8 mm. latum. [details]
Translation Rhizome stolonifère, subcespiteux ; stolons courts et robustes. Tiges (inflorescence non comprise) d’environ 50 cm de haut, feuillées à la base, à angles aigus, triquètres, entièrement lisses sous l’inflorescence. Feuilles de même longueur que la tige, de 4 à 8 mm de large, peu septées-nodulées, à nervures parallèles. Axe de l’inflorescence aigu triquètre, densément serrulé-hispidulé aux angles, très scabre ; entre-nœud inférieur de 3,5 à 4,5 cm de long, les autres très courts, bractées courtement engainantes (1 à 4 cm), linéaires. Inflorescence courte et dense, à 4 à 6 épis dressés longuement cylindriques, pédoncules de 5 à 12 mm de long, épis femelles de 4 à 7 mm de long et de 8 à 10 mm d’épaisseur, violacés ; épis mâles toujours solitaires, de 3 à 5 cm de long et de 5 à 6 mm de large, panachées de pourpre et de vert. Écailles femelles pourpre foncé avec une étroite bande verte sur le dos, 3 mm de long par 1 mm de large, étroitement elliptiques et se rétrécissant brusquement en une arête de 1 à 2 mm de long. Écailles pistillées (arête comprise) égalant ou dépassant le périgyne. Périgynes elliptiques, de 3 à 4 mm de long, étalés à l'horizontale, très denses, insérés de façon sub verticillée sur l'axe des épis, abruptement contractés en un bec sub-cylindrique de 1 mm de long se terminant par deux dents courtes, légèrement divergentes et lisses. Base des périgynes se terminant par un stipe étroit de 0,5 à 1 mm de long. Périgynes brillants, étroitement vésiculeux et coriaces, verts mais pourpres à l'apex et dans le bec, à nervures longitudinales nombreuses et épaisses. Akène oboval, à trois angles aigus, finement rugueux, jaune foncé, à apex arrondi en un style extrêmement flexueux à la base, décurrent, de 1,2 mm de long et 0,8 mm de large. [details]
Translation Rhizome stoloniferous, subcespitose; stolons short and robust. Stems (excluding inflorescence) approximately 50 cm tall, leafy at the base, sharply angled, triquetrous, completely smooth below the inflorescence. Leaves same length as the stem, 4 to 8 mm wide, slightly septate-nodulose, with parallel veins. Inflorescence axis sharply triquetrous, densely serrulate-hispidulate at the angles, very scabrous; lower internode 3.5 to 4.5 cm long, the others very short, bracts short-sheathing (sheath 1 to 4 cm long), linear. Inflorescence short and dense, with 4 to 6 erect, long-cylindrical spikes, peduncles 5 to 12 mm long, female spikes 4 to 7 mm long and 8 to 10 mm thick, purplish; male spikes always solitary, 3 to 5 cm long and 5 to 6 mm wide, variegated purple and green. Female scales 3 mm long by 1 mm wide, dark purple with a narrow green band on the back, narrowly elliptical and tapering abruptly into a 1 to 2 mm long awn. Pistillate scales (including awn) equal to or exceeding the perigynium. Perigynia elliptical, 3 to 4 mm long, horizontally speading, very densely arranged, insertion sub-verticillate on the axis of the spikes, abruptly contracted into a sub-cylindrical beak 1 mm long ending in two short, slightly divergent, smooth teeth. Base of perigynia ending in a narrow stipe 0.5 to 1 mm long. Perigynia shiny, narrow vesicular in shape and leathery, green but purple at the apex and in the beak, with numerous thick longitudinal veins. Achenes obovate, with three acute angles, finely roughened, dark yellow, with an apex rounded into a style strongly geniculate at the base, decurrent, 1.2 mm long and 0.8 mm wide. [details]
