Discussion

A common sedge of the central Rocky Mountains, Carex scopulorum var. bracteosa is distinguished from var. scopulorum by the scabrous stems and sheaths and by the narrower, more ellipsoid perigynia. It is usually distinguishable from var. prionophylla by the absence of bladeless, ladder-fibrillose sheaths; the two taxa may be difficult to identify in areas where both occur.
