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.
