CEGL001574 Panicum obtusum - Helianthus ciliaris Wet Meadow
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Vine-mesquite - Texas Blueweed Wet Meadow
Colloquial Name: Vine-mesquite - Texas Blueweed Playa Grassland
Hierarchy Level: Association
Type Concept: This association is an herbaceous wetland that occurs on flats, swales and seeps, or borders playa lakes at lower elevations ranging from 1500 to 1570 m (4925-5150 feet). Sites are wet and soils are heavy, clayey Vertisols (one stand was classified as a Typic Haplotorrert). It has been described from three areas in New Mexico, one within the eastern plains near Roswell, the second from the Jornada del Muerto and the last from the southern Animas Valley. Panicum obtusum is common to luxuriant, sometimes forming a broad band surrounding barren centers of the playas. Helianthus ciliaris is common in the herbaceous layer that often includes Scleropogon brevifolius, Aristida adscensionis, Eleocharis palustris, Ratibida tagetes, Portulaca oleracea, Phyla cuneifolia, Hoffmannseggia glauca, Sphaerophysa salsula and Melampodium leucanthum. A Panicum hallii phase has been described from highly degraded sites.
