Pond margins that are wet in spring and other seasonally wet spots. 0–1500 m. Casc, Est. ID, WA; north to AK, east to Newfoundland. Native and exotic. Carex crawfordii is a tufted, yellow-green plant with a tight head. It grows in the “bathtub ring” around a seasonal pond. It resembles C. athrostachya, but the inflorescence bracts are usually not prolonged beyond the end of the inflorescence, and the spikes and heads are more slender. Coastal plants were introduced in cranberry bogs, probably from northeastern North America. |
Nutrient-poor fens and bogs, floating peat mats; wet, peaty meadows and pond margins. 900–2200 m. BW, Casc. CA, NV, WA; north to AK, east to Newfoundland and DE, southeast to UT; Eurasia. Native. Carex limosa is a spiky little sedge. Each of the shoots bears a couple of short, erect leaves. The bract and the narrow male spikes point upwards. The short, broad female spikes hang downwards. Compare to C. pluriflora. |
