Promotes research and teaching in the taxonomy, systematics, and phylogeny of vascular and nonvascular plants.

Information of interest to systematists and other organismic biologists such as biological collections, taxonomic files, directories and ListServ archives, computer programs, reports by standards bodies (IOPI, ASC, SA2000, etc.), and access to on-lin

A Linnaean taxonomy arranged to show the evolutionary relationships among groups. One can navigate through the hierarchy vertically, or follow a lineage horizontally at a particular level of the hierarchy.

A global network of country-owned collaborative LOOPs to support national programs for biosystematics to support goals in areas such as sustainable development and pest management.

A project examining the phylogenetic tree of life and all of its features, with information and pictures for every class and an interactive, dynamic hierarchy.

A flexible format for encoding taxonomic descriptions for computer processing. It can be used to produce natural-language descriptions, keys, classifications, and information-retrieval systems.

Directory of specialists searchable by name, country, or specialization.
