Description:
This wetland community is found in the central Great Plains of the United States, where it occurs in shallow depressions on gently to moderately sloping topography. Soils are deep to moderately deep loams or clay loams underlain by a dense clay sublayer. Ponds often draw down periodically in these playa-type habitats. Annual herbaceous graminoids and forbs, mostly <1 m tall, dominate the exposed mud flats, and species composition and extent of the community fluctuate from site to site and year to year. In Nebraska, graminoids include <i>Cyperus acuminatus, Eleocharis engelmannii</i>, and <i>Echinochloa muricata</i>, and forbs include <i>Bacopa rotundifolia, Coreopsis tinctoria, Elatine rubella, Heteranthera limosa, Limosella aquatica, Lindernia dubia, Mollugo verticillata, Polygonum pensylvanicum, Polygonum lapathifolium, Rumex stenophyllus</i>, and <i>Sagittaria calycina</i>. In Kansas, graminoids include <i>Hordeum jubatum</i>, and forbs include <i>Ambrosia grayi, Symphyotrichum subulatum</i>, and <i>Chenopodium berlandieri</i>. The frequent water fluctuations and thick clay pan prevent establishment of most perennial hydrophytes, such as <i>Schoenoplectus</i> spp. and <i>Typha</i> spp.
