Species
Carex eggertii L.H.Bailey · unaccepted
Carex lupulina var. polystachya Schwein. & Torr. · unaccepted > superseded combination (Variety elevated to the rank of...)
Variety elevated to the rank of species, but the name Carex polystachya Sw. ex Wahlenb. (1803) was already used, necessitating the creation of new name (Carex lupuliformis).
Carex lurida var. polystachya (Schwein. & Torr.) L.H.Bailey · unaccepted > misapplication (This combination results from a...)
This combination results from a misapplication of the name Carex lurida Wahlenberg by L. H Bailey, who believed for a while that Carex lupulina Muhl. ex Willd was a junior synonym of Carex lurida.

Description Plants loosely cespitose or not, long-rhizomatous. Culms solitary or not, erect, 50–130 cm. Leaves 4–7; basal sheaths brownish; sheath of distal leaf 3–21 cm; ligules rounded to triangular, 6–28 mm; blades 30–80 cm × 6–13 mm. Inflorescences 6–40 cm; peduncles of proximal spikes 1–13 cm, basal 2 peduncles 2–17 cm apart; of terminal spikes 1–12 cm, shorter than to somewhat exceeding the distal pistillate spike; bracts leafy, sheath 1–9 cm; blades 20–70 cm × 4–11 mm. Spikes: proximal pistillate spikes 2–6, the distal usually ± crowded, ascending, densely 8–90-flowered, usually cylindric, 2–8 × 1.5–3 cm; terminal staminate spikes 1–2, 2–10 cm × 2–5 mm. Pistillate scales 3–9 veined, lanceolate, 6–13 × 1.8–3.2 mm, apex acute to awned, awn rough, to 5.5 mm. Anthers 3, 3.5–7 mm. Perigynia ascending to spreading, strongly 17–25-veined, sessile, lance-ovoid, 12–18.5 × 3.8–6 mm, shiny, glabrous; beak conic, 6–9 mm. Achenes stipitate, rhombic, concave faces, angles thickened, prominently knobbed with hard, nipplelike points, 3–4.5 × (2.2–)2.4–3.4 mm; style same texture as achene. [details]
