Introduction

Interactive key, including interactive information retrieval

The interactive key allows free choice of characters, is easy to use, and can lead to correct identifications in spite of occasional errors. It can display all the illustrations, full and partial descriptions, diagnostic descriptions, differences and similarities between taxa, lists of taxa exhibiting or lacking specified attributes, and distributions of character states within any set of taxa.
