Common (Translated Scientific) Name: Squarestem Spikerush - Arrowhead species Marsh

Colloquial Name: Squarestem Spikerush Coastal Depression

Hierarchy Level:  Association

Type Concept: This freshwater wetland type occurs on the Coastal Plain of Texas, most regularly near the coast with patchy occurrences inland. Most examples are found in small to moderately large ponds and swales that contain surface water during much of the year, desiccating only in the driest summer months. These wetlands are often fed by water runoff, but may result from percolation from adjacent sandy areas. Soils in the basins are finer textured than surrounding areas and may be underlain by pans that enhance perched water tables in the winter. Eleocharis quadrangulata is normally the dominant or codominant species, often forming more-or-less continuous colonies nearly covering the depressional areas. Other species that may be present include Sagittaria papillosa (primarily in more northerly examples), and Sagittaria longiloba (occurring primarily in more southern examples). Other common components include Steinchisma hians, Panicum virgatum, Cyperus haspan, Cyperus virens, Ludwigia glandulosa, Ludwigia linearis, Fuirena squarrosa, Xyris jupicai, Leersia hexandra, Centella erecta, Symphyotrichum subulatum, Sesbania spp., and Rhynchospora spp.
