Southeastern Alaska Distribution: Throughout, especially at lower elevations wherever there has been construction by man.
Habitat: Usually on moist sands and clay, in roadside ditches, marshes, gullies in glacial till, alluvial deposits, and similar, disturbed habitats.
Comments: Commonly with gemmae, never with sporophytes. Presumably this species would have had no difficulty in following the fluctuations of the ice margin during the Pleistocene as there would always be available suitable habitats in the disturbed terrain.
