Carex subspathacea, called Hoppner's sedge, is a species of flowering plant in the genus Carex , native to coastal salt marshes of the Arctic and northwest Pacific Oceans; Alaska, Canada, Greenland, Iceland, Norway, northern and far eastern Russia, Korea, and Japan. ^[2] It is grazed by snow geese ( Anser caerulescens ). ^[3]

Description

Carex subspathacea is a low-growing, rhizomatous sedge species, often growing in matted clumps in salty environments such as coastal salt-marshes. Leaves are long and narrow, growing up to 20 cm in height. Culms are smooth, usually shorter than the shoots. The inflorescence is a spike, fruiting in late summer. ^{[4] [5]}
