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.

The descriptions were generated from a DELTA database (Dallwitz 1980; Dallwitz, Paine, and Zurcher 1993). The bold parts are diagnostic descriptions, generated with the aid of Intkey (Dallwitz et al. 1993). They distinguish most taxa in at least one respect from the other taxa.
