About Eysenhardtia texana Scheele
Eysenhardtia texana Scheele, commonly called Texas kidneywood, bee-brush, or vara dulce, is a species of small flowering tree belonging to the legume family, Fabaceae. This species occurs from south-central Texas south to northern San Luis Potosí, within the Rio Grande Valley region spanning south Texas and northeastern Mexico, and its range extends into the eastern Chihuahuan Desert areas of Coahuila. The contiguous distribution of Texas kidneywood covers three neighboring northeastern Mexican states: Coahuila, Nuevo Leon, and Tamarulipas, plus the Rio Grande valley from Big Bend southeastwards. It does not grow in coastal Gulf of Mexico areas, only found 25 to 50 miles inland. A portion of its range extends south into extreme northern San Luis Potosí, and there are also isolated local populations in east-central and southern Texas.
