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.
