Trunk fluting

Trunk markedly fluted. When the outer surface of the trunk is not rounded and cylindrical but is marked by irregular vertical ridges and channels it would be placed in this category. The number of channels can vary from about 3 to 50 or more. This feature refers to the stem with the bark still attached. This feature is quite distinct from buttresses (see B47 and B48).
