found: Wikipedia, Aug. 27, 2014(Bulnesia is a genus of flowering plants in the caltrop family, Zygophyllaceae. The wood of some - particularly B. arborea and B. sarmientoi - is traded as verawood (colloquially "vera") or "lignum vitae". They are close relatives of the "true" lignum vitae trees of genus Guaiacum.)
