Carex brunnescens, the brownish sedge[2] or green bog sedge,[3] is a species of plant in the sedge family (Cyperaceae). It has a circumboreal distribution, and is native to North America and Eurasia.[4] In the United States it is primarily found in the Northeast and Midwest extending south into the Appalachian Mountains, with disjunct populations westward in the Rocky Mountains.[5] It has a wide-ranging natural habitat, is in found in forests, bogs, fens, and rock outcrops.[4][6]
Carex brunnescens is morphologically variable across its wide range. It has a different morphology when growing in shade vs. sunlight. Shade growing specimens tends to be slender and weak-stemmed with green scales, and sun growing specimens tend to be stiffly erect with brown scales.[4] The degree of variation in this species warrants further taxonomic study.[4]
