A Range Extension for Carex sartwellii in Interior Alaska
Our documentation of Sartwell’s Sedge, Carex sartwellii, on nine shrinking lakes during fieldwork in the central Yukon Flats, Alaska, represents a range extension for this species. Previously, its range extended as far northwest as Yukon, Canada, with a reported, but lost collection, from Alaska in...

Our documentation of Sartwell’s Sedge, Carex sartwellii, on nine shrinking lakes during fieldwork in the central Yukon Flats, Alaska, represents a range extension for this species.

Two earlier collections from the Yukon Flats have been verified; one was misidentified as Carex praegracilis until 2007.
