|Abstract||An attempt was made to provide an identification key, to trees of the former Netherlands East Indies, based solely on vegetative features. Most species flower or seed for limited periods. Only wild plants were included and only those reaching a diameter of 40 cm at chest height, a branchless trunk of at least 2 metres and a total height of 10 metres under favourable conditions. Species restricted to the East of the archipelago were omitted through lack of data.
Identification required only a x 10 magnifying glass and a sharp knife. The tables include 442 genera from 92 families. The families themselves were not distinguished, as the genus can more easily be defined; the species of one genus have more vegetative features in common than did a family. The features were selected so that the genera appear only in one or a few places in the key and that related genera or even families may be close together.
The tables are preceded by an annotated survey of the features used and some remarks on their systematic value.
