Plants cespitose, 10–40 cm tall. |
sheath fronts green and veined except for a small white-hyaline triangle at the top; blades 2–4.5 mm wide. |
3–4 mm wide. |
1–4.5(6) cm × 5–14 mm, typically elongate; spikes distinct but overlapping, gynaecandrous, rounded or tapered to tip. |

trigonous, filling less than half of the perigynium body. |
2.2–3.7 mm long; shorter and narrower than the perigynia, white-hyaline; aging silvery brown, with green center; apex obtuse. |

Bogs and pond shores, on peaty or sandy soils, often where water levels fluctuate greatly, sometimes a weed in cranberry bogs. 0–50 m. Est. WA; eastern North America, HI, Central America, Caribbean; New Zealand. Exotic. Carex longii is cespitose and has a silvery-green, elongated inflorescences and green leaf sheath fronts. It strongly resembles native C. feta, which has rounder spikes and perigynium bodies widest near the middle. |
Alpine slopes, ridges, boulder fields, talus slopes, and rocky streamsides. 2500–3100 m. BR, BW. ID, NV; northeast to MT, east to UT and CO. Native. Carex pelocarpa is an alpine sedge with dark, sessile spikes. It is similar to C. media, which also has sessile spikes, but C. media grows in lower elevation, often wetter habitats and has smaller, green perigynia that are nearly filled by the achene. Its spikes usually have more contrast of dark scales with light perigynia, in part because the scales are usually less than half as long as the perigynia. Carex pelocarpa and C. nova have sometimes been treated as the same species. |
