Name: A.1680
Reference: EcoArt 2002
Description: This lush herbaceous alliance has been described from semipermanently flooded areas in the mountains of western Wyoming. Elevations are 1700-1800 m. Stands occur on moderate to steep, mid and lower slopes and toeslopes near seeps. Soils are saturated, but not stagnant, and composed of a sandy-textured mineral horizon with a thin organic layer. Stands have a medium-tall (0.5 m), moderately dense to dense herbaceous layer that is codominated by the perennial forbs ~Senecio triangularis$ and ~Mimulus guttatus$. Associated species include mesic and wetland forbs such as ~Epilobium$ spp., ~Mimulus lewisii, Mitella pentandra, Parnassia fimbriata, Saxifraga odontoloma$, and the graminoid ~Agrostis exarata$. Mosses form a nearly continuous ground cover between the forbs. Shrubs and trees are not present.
