Powerpoint presentation given by Anna Haigh at the Kikforum. As part of the CATE project we are developing keys in Lucid 3 to the genera of Araceae, and to the genus Anthurium (ca. 800spp.), Arum and Philodendron. The key to Arum is already online. These keys will be incorporated into a web-based taxonomic revision of the Araceae family as the plant model group for the project. Anthurium presents a particular challenge as it is a very large and difficult genus, within which it is currently nearly impossible for non-specialists to determine plants to species. We hope the key will go some way to solving this problem.
