spring sedge, woodrush sedge
|
|
Plants cespitose to short-rhizomatous, 15–90 cm tall; culms much longer than the leaves. |
|
sheath fronts whitish hyaline; blades 3–9 mm wide, glabrous. |
|
lowest bracts with more or less inflated sheaths (5)10+ mm long; lateral spikes crowded around the terminal one or separated; erect and nearly sessile or the lower ones drooping on long; slender peduncles; female or androgynous, 1.2–3.2 cm long; terminal spike male, 1.1–6.6 cm long. |
|
(3)3.5–5.5 × 0.9–1.6(1.8) mm; either mostly purple, or green with reddish or purple spots, usually glabrous, sometimes with sparse, spreading to appressed, usually long; soft; thin hairs, with several inconspicuous veins; beak with distance from achene top to beak tip less than 2.5 mm; stigmas 3. |
|
trigonous. |
|
shorter than the perigynia; reddish brown to dark purplish with a light mid-stripe; margins sometimes white, glabrous. |

Bogs and wet meadows. 600–3000 m. BR, BW, Casc, CR, ECas, Est, Sisk. CA, ID, NV, WA; north to British Columbia, east to WY. Native. The broad, yellow-green leaves clustered at the base of the culm, together with the inflorescence bracts with more or less inflated sheaths, the pointy perigynia, and the reddish to purplish female scales, make C. luzulina unlike any other sedge in Oregon bogs. However, it is hard to point at any one consistent feature as identifying this species. Two varieties (sometimes treated as species) have been recognized in C. luzulina, but the traits supposedly distinguishing them vary independently. Variable C. luzulina is confused with Californian C. luzulifolia and C. fissuricola, which usually have perigynia with flat margins more than half as wide as the achene. In C. fissuricola, the perigynium faces, at least near the beak, have sparse, spreading-ascending, short, stiff bristles, and the pistillate scales have hairs on the distal margins. |
