Description Perennials. loosely caespitose, with long creeping rhizomes. Stems 20-70 cm tall, obtusely trigonous, smooth on lower part and scabrid on top. Leaves longer than or equaling stem, 4-8 mm wide, light green, scabrous. Basal sheaths yellowish brown, soft, slightly fibrillose. Involucral bracts leaflike, longer than inflorescence, usually without sheaths or sometimes lowermost one shortly sheathed. Inflorescences spikes usually 3; terminal spikes male, clavate, 1.5-2 cm long, shortly pedunculate; lateral spikes female, rather approximate, subglobose or oblong-ovate, 1.5-2 cm long, densely many flowered, nearly sessile. Staminate scales pale brown, midrib broadly light green, apex acuminate. Pistillate scales pale brown, midrib broad, green, apex acuminate or shortly aristate. Perigynia stramineous or yellowish brown, obliquely patent, later horizontally patent or reflexed, much longer than pistillate scales, broadly ovate or ovate, inflated trigonous, ca. 10 mm long, 5-veined abaxially, apex gradually narrowed to a stiff beak, mouth bidentate. Achenes broadly rhomboid, trigonous, ca. 3 mm long. Stigmas 3. [details]

Taxonomic remark Les bractées dépourvues de gaines, les épillets femelles formés de fleurs nombreuses, les périgynes largement ovales à la base, distinguent bien le C. Dickinsii du C. rostrata Michx (C. Michauxiana Boeck.). Par ses bractées et la forme du périgyne, il se rapproche davantage du C. intumescens Rudge; mais cette espèce a des épillets femelles pauciflores et ses périgynes sont parcourus par de nombreuses nervures très-fines qui disparaissent presque à la maturité. Le C. Grayi, dont les bractées sont également dépourvues de gaines, a ses épillets femelles, quoique formés de 15-20 fleurs seulement, presque une fois plus larges (3-4 cent.), à cause de la dimension du périgyne qui atteint jusqu'à 18 mill. de longueur. Le C. lupulina s'éloigne davantage par sa bractée inférieure plus ou moins engainante et surtout par les écailles des fleurs mâles et femelles qui ne sont pas dissemblables et beaucoup plus étroites.

Taxonomic remark Les bractées dépourvues de gaines, les épillets femelles formés de fleurs nombreuses, les périgynes largement ovales à la base, distinguent bien le C. Dickinsii du C. rostrata Michx (C. Michauxiana Boeck.). Par ses bractées et la forme du périgyne, il se rapproche davantage du C. intumescens Rudge; mais cette espèce a des épillets femelles pauciflores et ses périgynes sont parcourus par de nombreuses nervures très-fines qui disparaissent presque à la maturité. Le C. Grayi, dont les bractées sont également dépourvues de gaines, a ses épillets femelles, quoique formés de 15-20 fleurs seulement, presque une fois plus larges (3-4 cent.), à cause de la dimension du périgyne qui atteint jusqu'à 18 mill. de longueur. Le C. lupulina s'éloigne davantage par sa bractée inférieure plus ou moins engainante et surtout par les écailles des fleurs mâles et femelles qui ne sont pas dissemblables et beaucoup plus étroites. [details]
Translation The bracts have no sheaths, the female spikelets have numerous flowers, and the perigynia are broadly ovate at the base, all of which distinguish C. dickinsii from C. rostrata Michx (C. Michauxiana Boeck.). The bracts and shape of the perigynia are closer to those of C. intumescens Rudge, but this species has female spikelets with fewer flowers and its perigynia are covered with numerous very fine veins that almost disappear at maturity. C. Grayi, whose bracts are also devoid of sheaths, has its female spikelets, although formed of only 15-20 flowers, almost once as wide (3-4 cm), due to the size of the perigynum, which reaches up to 18 mm in length. C. lupulina differs further in its more or less sheathing lower bract and especially in the scales of the male and female flowers, which are not dissimilar and much narrower. [details]
Translation Plant pale green, a bit flaccid; rhizome creeping, thin; culms ½-2 feet high, slender, obtusely triangular, only scabrous at the apex under the spikelets, with leaves inserted up to the middle; leaves slightly exceeding the culms, 3-4 mm wide, very scabrous at the margins and underneath, long sheathing, apex of sheaths with a ligule on both sides, both ligules similar, ovate, 2-3 mm long; lower bract sheathless, with a blade equaling or exceeding the culms; male spikelet solitary, 1½-2 inches long, 3 mm wide, linear, long pedunculate, with dirty whitish scales, oblong, obtuse or acute, with a single nerve on the back, sometimes awnless, sometimes with a short awn, awn scabrous; female spikelets 2, subsessile, contiguous, densely floriferous, 25-40 flowers, subglobose, or ovate, or obovate,1¼-3 cm long, 1½-2 cm wide, pistillate scales covering about half the length of the perigynia and a third of its width, ovate, sides dirty reddish, back greenish, three-nerved, middle nerve ending in a short, scabrous arista; style trifid; mature perigynium, 10-12 mm long, base broadly ovate, 3 mm wide, stramineous (juvenile dark brown), 13-15 nerves prolonging into a long beak. Beak with smooth edges, ending with two teeth; achene loosely enclosed, broadly ovate, acutely triangular, dark brown, papillose scabrid, apex attenuated, long mucronate. [details]
