Abstract To facilitate further discussions and to inform tropical forestry experts, the formation and anatomy of bark were reviewed in association with its terminology. Sections deal with: secondary phloem; dilation and sclerosis; their influence on primary bark parts and on secondary phloem; interxylary phloem; pith ducts; periderm; lenticels and dead outer bark. Next follows an analysis of what could usually be seen of the anatomy of the bark and the crust with a x 10 lens and with the naked eye. The features noticed were then evaluated as distinctions for bark species. Information was given on odour and taste.

Then follow descriptions of 60 investigated barks of the Indonesian Archipelago, analysed by these means. A x 10 lens proved sufficient for identification.

The sequence of bark features from common to special features was shown to be usually: cork layer, stone cells, fibres, soft bark parts, secretory organs, bark rays, while the primary bark parts, often having disappeared, could only serve as distinguishing features for a limited number of barks.

If the number of bark parts considered were to be further enlarged the use of a x 20 lens might become necessary.
