Carex disticha

Tracheophyta MagnoliopsidaCyperaceaeCarexCarex disticha


This rhizomatous species is found in wet meadows and marshes, fens, by ditches and streams, on the margins of lakes and ponds, and occasionally in dune-slacks. It almost invariably grows in well-illuminated sites, particularly on base-enriched substrates, and favours areas with a fluctuating water table. Generally lowland, but reaching 455 m on Windburgh Hill (Roxburghs.).
