Kumbuk
a large Indian tree. The bark is used for tanning black. It imparts the characteristic red color to native leather, and, if cut up into small pieces and boiled for six hours, gives a brown dye. Along with the bark of Mimusops elengi it is used to produce a red dye in jute. It affords a black one with iron. The wood is much used on account of its toughness for making shafts to gigs.
