Condalia hookeri

Condalia hookeri, called the Brazilian bluewood, is a widespread species of flowering plant in the family Rhamnaceae, native to Texas and eastern Mexico. It is a thorny shrub or small tree reaching 6 m but usually much shorter. Typically it is found growing in marginal habitats such as limestone slopes, sandstone bluffs, lunettes, shell ridges, juniper-dominated woodlands, or along watercourses, often in clayey or sandy soils, at elevations from 30 to 1300 ft. It may come to dominate an area as a thorny scrubland.

Names
Condalia hookeri goes by a number of misleading common names, including Brazilian bluewood, bluewood condalia, brasil, brasilwood, bluewood, logwood, purple haw, Edwards' bluewood, and capul negro, some of which are shared by other members of its genus. Some of the names refer a blue dye that is obtained from its dense wood.
