B 1 smooth To be included in this category the bark must be very smooth and shiny, at least as smooth as the bark on a typical gum-barked eucalypt, e.g. The upper trunk of Eucalyptus grandis.
B 2 fissured When the outer dead bark splits and opens up in longitudinal grooves it can be included in this category. The fissures may be either much narrower than their depth or they can be wider than their depth.
B 3 tessellated To be included in this category the outer dead bark must be broken up into flakes or plates which are nearly square or rectangular in outline and must form a regular pattern. This is an uncommon bark type in rain forest.
B 4 papery The bark is shed in rather large, thin, flexible flakes, e.g. Tea Tree (Melaleuca spp.). This is an uncommon bark type in rain forest.
B 5 flaky The bark is shed as irregularly shaped flakes of any size.
B 6 nondescript This includes bark types which do not fit into any of the previous categories. This is the common bark-type in rain forest.
