Description:
Subtropical shrublands dominated by ~Ebenopsis ebano (= Pithecellobium ebano)$ and ~Phaulothamnus spinescens$ with other xeromorphic shrubs. Vegetation in this alliance is dominated by tall, thorny shrubs, 3-4 m tall. These shrublands can occur on the well-drained portions of clay dunes within coastal tidal flats, where they are influenced by salt spray, high winds, and extreme xeric conditions. Shrublands in this alliance can also occur over clayey soils on river levees, resaca banks, and elsewhere in the Holocene floodplain of the lower Rio Grande. Associated species in maritime areas include ~Yucca treculeana, Maytenus phyllanthoides, Citharexylum berlandieri, Ziziphus obtusifolia, Leucophyllum frutescens, Zanthoxylum fagara, Prosopis glandulosa, Karwinskia humboldtiana, Phaulothamnus spinescens, Forestiera angustifolia, Opuntia engelmannii var. lindheimeri, Sideroxylon celastrinum (= Bumelia celastrina), Havardia pallens (= Pithecellobium pallens)$, and ~Condalia hookeri var. hookeri$. In river levee shrublands, associates include ~Sideroxylon celastrinum, Condalia hookeri, Ziziphus obtusifolia, Zanthoxylum fagara, Prosopis glandulosa, Celtis pallida, Ehretia anacua, Karwinskia humboldtiana$, and ~Adelia vaseyi$. Associations within this alliance are uncommon, known only from southernmost Texas, from the Holocene floodplain and delta of the lower Rio Grande, although the dominant species are known to range into northern Mexico.
