Integrating Plant Systematics

Stevens, P. F. [1].

Seed Plant Phylogeny: building consensus, integrating change.

Over the last fifteen years there has been a major reorganization of our knowledge of higher-level relationships (Families, orders and above) in seed plants. Eight years ago the Angiosperm Phylogeny Groups suggested a consensus classification or orders and families that has been widely adopted. Change continues apace, although for the most part it is more in detail (Hydatellaceae, Rafflesiaceae); changes will also occur in the big picture of relationships, but are unlikely to affect the taxa that are the focus of the site. As part of the effort to maintain and develop taxonomic consensus, the Angiosperm Phylogeny website has for the last six years integrated new findings in phylogeny, morphology and chemistry in the context of the APG classification. Links to images and other sites are included, as are maps, references to plant-animal interactions, major revisions, and species synonymies, etc. New information is evaluated against the background of our overall understanding of phylogeny and morphology and presented to the user in a strictly phylogenetic and hierarchical context. The site is designed to be used by biologists of all persuasions (there is an extensive bibliography and glossary), both teachers and researchers, and to present the most recent findings both accurately, critically and quickly. A version of the site to be used by undergraduates is also being developed. The principles underlying the site are discussed, its strengths and weaknesses, and its short- and long-term goals.
