Carex feta, the green-sheathed sedge or greensheath sedge, is a species of flowering plant in the family Cyperaceae, native to southwestern British Columbia in Canada, and Washington, Oregon, and California in the United States.[1] [2]
The leaf blade is between 2.5 and 5 mm long, with a triangular white patch. The open inflorescence is between 30 and 80 mm long, which are white-green to pale gold in color. The fruit is between 3 and 4.2 mm in diameter, green to pale gold in color, and either ovate or wide-ovate. The fruiting time is between the months of May and August.
