The variety urbiniana (or subspecies) is found in the mountains of Nuevo Leon and Veracruz in eastern Mexico. The form xanthocarpa occurs in parts of New York.

It is very valuable and is sometimes sold by the pound, because clear Dogwood is very limited in supply. It has the advantage of being hard, smooth, and pleasing to the eye, but it is rarely found in the home workshop. Comments About 90 percent of all its timber is used commercially for making shuttles for textile weaving.
