Stream banks, bogs, meadows, and open forests, on stable, usually calcareous substrates that are wet in spring but may dry out later. 1600–2500 m. BW. North to AK, east to Newfoundland. Native. Carex concinna is recognized by its hairy perigynia, tiny staminate spike, and absent or tiny inflorescence bract. It lacks basal spikes among the leaf bases. |
Dry grasslands, mesic meadows and open forests. 600–2800 m. BR, BW, Casc, ECas, Sisk. CA, ID, NV, WA; northeast to MT. Native. Carex pachycarpa is a “ball-headed” bunchgrass sedge with large, pale, shaggy heads. Its pale perigynia have smooth oval bodies and wings that are broad near the beak but taper smoothly to become narrow beside the achene. Dorsal perigynium veins may appear impressed rather than raised. Individuals in the Warner Mountains may have unusually long, lanceolate perigynia. Other montane upland species (within subkey 9) with dense heads have darker or more compact inflorescences. This species can be confused with Californian C. multicostata. |
