Additional close-up photos of water sedge as seen in a ditch alongside Forest Service Road 16 in Summit Prairie, Malheur National Forest..............August 2, 2011. Note that the scales subtending each perigynia are reddish-margined with a broad, light-green central band. The scales are longer but much thinner than the perigynia. Note also the chestnut-brown base of the culm and rhizomatous nature of this plant.
