Description:
This deciduous woodland association occurs on non-saline, coarse- and fine-textured Beaumont Formation strata in the lower Rio Grande Valley of Texas and Tamaulipas, Mexico. It is characterized by a scattered to open (or nearly closed) canopy emergent over a dense and diverse shrub layer with openings supporting grasses and forbs. Prosopis glandulosa var. glandulosa typically dominates the emergent canopy. Other canopy species include Acacia greggii var. wrightii (= Acacia wrightii), Celtis laevigata var. laevigata, Celtis pallida, Ebenopsis ebano (= Pithecellobium ebano), Havardia pallens (= Pithecellobium pallens), and Sideroxylon celastrinum (= Bumelia celastrina). The shrub layer is very dense and diverse, including Acacia berlandieri, Acanthocereus tetragonus (= Acanthocereus pentagonus) (in eastern portion of lower Rio Grande delta only), Adelia vaseyi, Aloysia gratissima, Amyris madrensis, Amyris texana, Bastardia viscosa, Borrichia frutescens (in openings), Capsicum annuum var. glabriusculum, Castela erecta ssp. texana (= Castela texana), Celtis pallida, Citharexylum berlandieri, Condalia hookeri, Diospyros texana, Chromolaena odorata (= Eupatorium odoratum), Xylothamia palmeri (= Ericameria austrotexana), Forestiera angustifolia, Guajacum angustifolium, Isocoma drummondii, Jatropha dioica, Karwinskia humboldtiana, Koeberlinia spinosa, Lycium berlandieri, Malpighia glabra, Maytenus phyllanthoides, Opuntia engelmannii var. lindheimeri, Opuntia leptocaulis, Phaulothamnus spinescens, Randia rhagocarpa, Yucca treculeana, Zanthoxylum fagara, and Ziziphus obtusifolia var. obtusifolia. Callisia micrantha may be locally dominant in the ground cover beneath the shrubs. Herbaceous components are generally better represented in openings and may include Chloris pluriflora, Pappophorum vaginatum, Sidastrum paniculatum, Sporobolus wrightii, Billieturnera helleri, and Tamaulipa azurea (= Eupatorium azureum). This woodland may grade into woodlands or shrublands dominated by Acacia rigidula, Acacia berlandieri, or Ebenopsis ebano or may form a mosaic with Bothriochloa barbinodis - Chloris pluriflora Herbaceous Vegetation (CEGL002236) (Diamond 1993). This community is often impacted by the invasive grass Pennisetum ciliare.
