Type Concept: This deciduous forest occurs on silty to clayey alluvial soils on stream terraces in southern Texas north of the Lower Rio Grande Valley. Celtis laevigata var. laevigata and Ulmus crassifolia are generally the clear canopy dominants; Fraxinus berlandieriana, Fraxinus pennsylvanica, and Sapindus saponaria var. drummondii are usually present. Celtis ehrenbergiana occurs either in a poorly defined subcanopy or in the shrub layer, which ranges from open to choked with woody vines such as Toxicodendron radicans, Smilax bona-nox, and Vitis mustangensis. Ground cover on well-developed level terraces is dense and grassy, dominated by Elymus virginicus, along with Chasmanthium latifolium, and Nassella leucotricha. Characteristic forbs include Clematis pitcheri, Stellaria prostrata, Dicliptera brachiata, Rivina humilis, Chaerophyllum tainturieri var. tainturieri, and Galium aparine. This community is similar to other communities in this alliance but differs in the presence of southern elements such as Celtis ehrenbergiana and the absence of subtropical elements that distinguish ~Celtis laevigata - Ulmus crassifolia - (Fraxinus berlandieriana) / Rivina humilis - Chromolaena odorata Riparian Forest (CEGL007752)$$.

Floristics: The canopy is dominated by Celtis laevigata var. laevigata and Ulmus crassifolia. Other canopy components include Fraxinus berlandieriana, Fraxinus pennsylvanica, and Sapindus saponaria var. drummondii. The open to closed subcanopy and shrub layer may include Celtis ehrenbergiana (= Celtis pallida), Toxicodendron radicans, Smilax bona-nox, and Vitis mustangensis. Ground cover on well-developed level terraces is dense and grassy, dominated by Elymus virginicus, along with Chasmanthium latifolium and Nassella leucotricha. Characteristic forbs include Clematis pitcheri, Stellaria prostrata, Dicliptera brachiata, Rivina humilis, Chaerophyllum tainturieri var. tainturieri, and Galium aparine.
