Ayous or Samba
Observations

Although it is the same botanical species, it is marketed under two names:

  • SAMBA (Ivory Coast): may have mineral stain and bluish wood – In the The molding sector is usually used when it is covered with paper or sheet metal and/ or if it is not lacquered or varnished in its natural color since when varnished they would be appreciated these stains, therefore it is necessary to dye it.
  • AYOUS (Cameroon): Wood most selected by color, it is usually whiter.
