CEGL007760 Acacia rigidula - Leucophyllum frutescens - Hechtia glomerata Shrubland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Blackbrush Acacia - Texas Barometerbush - Guapilla Shrubland
Colloquial Name: Chaparro-Prieto - Cenizo - Guapilla Shrubland
Hierarchy Level: Association
Type Concept: This community occurs on fossiliferous (primarily with oyster shells) and somewhat gypseous clays of the Yegua Formation and other Eocene formations in southern Texas. The soils are eroded calcareous clays which, though far from the coast, are slightly saline. This shrubland is usually low in stature, with few emergent shrubs. Hechtia glomerata, generally absent from other blackbrush-dominated shrublands, is common and characteristic. Other important shrubs include Condalia spathulata, Krameria ramosissima, Guaiacum angustifolium, and Karwinskia humboldtiana. Ten or more species of small cacti are often present; Agave parryi ssp. parryi and Agave univittata are present at some sites. Citharexylum brachyanthum, Jatropha dioica, and Castela erecta ssp. texana are also sometimes present.
