Shasta sedge
|
Lyngbye's sedge
|
| Plants cespitose, 20–50 cm tall. |
Plants rhizomatous, but the deep rhizomes often not collected; forming dense stands; culms 25–130 cm tall; plant bases reddish brown. |
3–4 mm wide; flat or folded. |
sheath fronts hyaline, not spotted, not ladder-fibrillose; blades 3–8 mm wide, green; smooth-edged; dying in winter. |
1.3–3 cm × 12–20 mm; spikes 3–8, crowded but distinguishable, gynaecandrous. |
lowest bract usually longer than the inflorescence; lateral 2–4 spikes female or androgynous, dangling on curved peduncles (but the spike itself does not bend), usually truncate at the base, 1.8–5 cm × 5–7 mm; terminal 2–3 spikes male. |
broadly ovate; flat, 4–5.8 × 1.8–3.4 mm; straw-colored, green, or whitish with brown tip; widest below middle of total perigynium length, with 10–20 dorsal veins and 1–12 ventral veins; wings 0.4–1 mm wide; the edges often crinkled; beak winged and ciliate-serrulate to near the tip, or sometimes unwinged, brown; parallel-sided; and entire for the distal 0.5–0.7 mm, 2.2–3 mm from achene top to beak tip; stigmas 2. |
ovate to obovate, 2.5–3.5 × 1.6– 2.5 mm; yellowish brown with pale brown spots, 5–7-veined on each face; beak 0.1–0.3 mm long; stigmas 2. |
lenticular, located below the center of the perigynium; (1.4)1.7–2.4 × 1–1.6 mm. |
lenticular, often with a dent in the side. |
lanceolate to ovate, 3.2–4.8 mm long; shorter and narrower than the perigynia, white to reddish brown with pale mid-stripe; apex acute to acuminate. |
longer than the perigynia; reddish brown to dark purplish brown, acuminate. |

In rocky or gravelly soils, dry open slopes, sometimes in open forests, at or near timberline, often near persistent snowbanks. 1500–2800 m. Casc, ECas. CA, ID, NV, WA; northeast to MT, southeast to UT. Native. Carex straminiformis is a coarse, tough sedge with spikes that show a lot of contrast between pale perigynia and dark scales. The broad, flat, “potato chip” perigynia clinch the identification. Carex brevior has equally wide but plano-convex perigynia, and it grows only at low elevations. |
Coastal salt marshes and in more or less fresh water along the lower Columbia River. 0–50 m. CR, Est. CA, WA; north to AK, east to Greenland; Europe. Native. Carex lyngbyei forms extensive stands in coastal salt marshes. Its female spikes are relatively short, with truncate bases, dangling at the ends of curved stalks. Similar C. obnupta and C. aquatilis var. dives grow in fresh to brackish water, sometimes adjacent to C. lyngbyei stands. Both have longer, usually sessile female spikes with tapered bases. |
