Floodplain forests, lake shores, swamps, streamsides, wet thickets, wet meadows, in sites that are soggy wet in spring but may dry out on the surface later in the season. 0–1000 m. BW, Col, WV. ID, WA; north to British Columbia, east to New Brunswick. Native. Carex retrorsa is a robust, cespitose sedge with its spikes all nestled near the bases of its long inflorescence bracts. Its male spikes are located among the clustered female spikes. One’s first impression might be that this is a deformed C. utriculata or C. vesicaria; both of these species have spikes more separated, with the male spikes held distinctly above the female ones, and with inflorescence bracts not more than 2.5 times as long as the inflorescence. In addition, C. utriculata is strongly rhizomatous. |
