Ehretia anacua
Species of tree
Ehretia anacua is medium-sized tree found in eastern Mexico and southern Texas in the United States. It is a member of the borage family, Boraginaceae.[1] One of its common names, anacua, is derived from the Mexican Spanish word anacahuite, as is that of the related Cordia boissieri, the anacahuita.[2] That word in turn is derived from the Nahuatl words āmatl, meaning "paper," and cuahuitl, meaning "tree,"[3] possibly referring to the bark. It is also known as knockaway, a corruption of anacua, and sandpaper tree.[2] Alternate spellings are anaqua and anachua.[4]
