Carex.
Botanical name:
CAREX, L. Sedge. A tribe of grasses rather than genus: nearly 150 species lately ascertained with us, by Schweinitz, Torrey, Dewey, and myself. Not much liked by cattle: the large kinds make a rough kind of hay; those of salt marshes rather better owing to the salt taste; useful to consolidate marshes and sands. Those with odorous roots are medical, like C. arenaria of Europe, edible, stomachic, diuretic, equivalent of sarsaparilla, gayac and Dactylon.
