A lignitized wood of Miocene derivation has been identified to the genus Taxodium. The cell walls of latewood tracheids are Mäule positive. A structurally intact lignin residue is obtained after incubation of the wood in 72 percent sulfuric acid. Cellulose persists as a structural polysaccharide in the lignitized wood.
