Type Concept: This herbaceous vegetation occurs from California to British Columbia and eastward at 12 to 152 m (40-500 feet) elevation. Habitat is low-elevation beds of dried shallow seasonal pools and lakes. Soils are seasonally flooded to saturated silt loam. Trees are peripheral and not included in plots, but the setting is usually adjacent to bottomland forest of Fraxinus latifolia and Populus balsamifera ssp. trichocarpa. Salix lucida ssp. lasiandra is present in half the sampled plots, and Salix fluviatilis is also often present, but neither occurs in large amounts. The herb layer contains about 20 annual and perennial species adapted to early-season inundation and subsequent exposure as lakes and ponds dry up. Most exotic species are excluded by inundation extending into the growing season. Eragrostis hypnoides is the primary species with an average cover of 37% and cover ranging up to 85%, while Gnaphalium palustre has somewhat lower constancy but similar cover when present. Lindernia dubia forms patches in some stands. The remaining species occur only in trace amounts. Eragrostis hypnoides forms a loose and patchy sod with Gnaphalium, and considerable bare ground may be present. These sites appear to be drier than those occupied by the mudflat vegetation of Lilaeopsis occidentalis or Azolla associations, the mud often cracking deeply and the top layer losing most of its moisture.
