Taxonomic datasets on DVD or thumb drive

L. Watson and M. J. Dallwitz

A DVD or thumb drive containing all of the datasets listed below is available from L. Watson for AU$40. Each dataset contains the same material as the Web package (that is, an interactive key and information retrieval system, descriptions, and illustrations), plus the DELTA data from which the Web package is generated.

The interactive keys use the Intkey app. A version for Microsoft Windows is included. Installation is not needed: it runs directly from the DVD or thumb drive. A version for Mac OS is available at
