The leaves of this tree are very rough and are used in some localities 

 for polishing wood, etc. The leaves are also rich in tannic acid and 

 are locally used for tanning purposes. In South America Gilg notes 

 (Engler & Prantl, "Die Natiirliche Pflanzenfamilien," III (Abt. VI), 

 1895, p. 114) that it is especially common in the "catinga" formation.
