IllustratedEndemic
Synonyms: Carex nova var. pelocarpa (F. J. Hermann) Dorn
Treatment appears in FNA Volume 23. Treatment on page 412. Mentioned on page 402, 410.

Plants cespitose. Culms 10–40 cm, smooth. Leaves 3–4 mm wide. Inflorescences: proximal bracts shorter than, sometimes equaling or, occasionally, exceeding inflorescences; spikes overlapping, contiguous, forming a dense terminal cluster or, sometimes, proximal spikes separate and distinct, sessile, short-oblong, 7–10 × 5–7 mm; lateral 2–3 spikes pistillate; terminal spike gynecandrous. Pistillate scales dark-brown or black to margins, lanceolate, shorter or longer than, and narrower than, perigynia, midvein same color as body, inconspicuous, apex usually acute, occasionally short-mucronate. Perigynia ascending, glossy reddish-brown, often with yellowish or greenish brown margins, veinless, obovate or circular, 3.5–4.5 × 2.5–3 mm, apex abruptly beaked, smooth; beak 0.5–0.8 mm, deeply bidentate, smooth. Achenes filling proximal 1/2 or less of perigynia.


Phenology: Fruiting Jul–Aug.
