Name: Pascopyrum smithii - Buchloe dactyloides - (Phyla cuneifolia, Oenothera canescens) Herbaceous Vegetation
Reference: Midwestern Ecology Working Group...
Description: This wheatgrass playa grassland community represents the common vegetation type of playa lake basins (depressional wetlands) under rangeland conditions in the southern and central Great Plains of the United States. In the central Plains soils are dense silts and clays, occasionally loess-derived, that flood in winter and dry out by early summer. Perennial herbaceous graminoids and forbs <1 m tall dominate the community, with composition varying depending on water levels. In the central Plains <i>Pascopyrum smithii</i> is most abundant, with <i>Agrostis hyemalis, Eleocharis palustris, Eleocharis macrostachya, Elymus virginicus</i>, and <i>Hordeum jubatum</i> locally abundant. <i>Buchloe dactyloides</i> can be abundant in grazed sites. Early-season ephemeral annuals include <i>Alopecurus carolinianus, Elatine rubella, Myosurus minimus, Veronica peregrina ssp. xalapensis</i>, and more westward <i>Limosella aquatica</i> and <i>Plagiobothrys scouleri</i>. Perennial forbs, including <i>Ambrosia grayi, Phyla cuneifolia, Oenothera canescens, Rorippa sinuata</i>, and <i>Vernonia fasciculata</i>, are conspicuous in places. In the southern Plains, species characteristic of the type include <i>Buchloe dactyloides, Distichlis spicata</i>, and <i>Panicum obtusum</i>.
