Rhynchospora fusca (L.) W. T. Aiton
Common Name: BEAK-RUSH
Coefficient of Conservatism: 7
Coefficient of Wetness: -5
Wetness Index: OBL
Physiognomy: Nt P-Sedge

Sandy-peaty shores, interdunal hollows, sandy excavations, boggy meadows; occasionally on bog mats but more often at remnants of bogs and often in somewhat marly places.

The very slender involute-filiform leaves and elongate, creeping rhizomes of this species will distinguish it quickly from the flat-bladed, cespitose R. capitellata, if achenes are not available for examination of the barbs on the bristles.
