English: The bunched Carex kelloggii and the taller-statured and rhizomatous Carex utriculata were the two most common wetland sedges along the John Muir trail system, including here along the shores of Middle Rae Lake. They often dominated the margins of ponds and lakes. Carex utriculata usually stood about a meter tall whereas Carex kelloggii about half that height. The bunched growth habit along lake and pond margins combined with narrow-cylindrical pistillate spikes of green veinless perigynia each enclosing a lenticular achene are distinguishing of Carex kelloggii.
