Limestone Meadow Sedge

Carex granularis Muhl. ex Willd.

Comments

provided by eFloras
Carex granularis is widely distributed and common across the eastern half of the United States and southeastern Canada, but not on the Coastal Plain or in the high Appalachians. It varies not only in the dimensions and ultimate overall shape of the perigynia but also in less tangible features, such as texture, color, and amount of red speckling on the perigynia, prominence of perigynia veins, and papillosity of achene surface. One phase distinguished by the smaller, slightly less inflated, more ellipsoid perigynia with more pointed apices and finer veins has often been treated as C. haleana or C. shriveri; it intergrades rather freely with typical C. granularis. Because of the subtlety of the distinctions, the intergradation in morphology, and the difficulties presented by specimens in immature stages or distorted during preparation, we maintain C. granularis as a single variable species without infraspecific taxa. An apparent hybrid between C. granularis and C. flaccosperma Dewey or C. glaucodea Tuckerman ex Olney is known from one locality in Arkansas.
