Flowering Plant Gateway
Gatekeeper: Hugh D. Wilson

The selection options on this page, and the menu bar below, provide various paths for exploration or comparison of four systems of flowering plant classification.  Selection of a Family name will query an index of web links relating to that Family or included taxa.  This 'gateway' system - eventually to include all vascular plants - is under constant revision.  Current options (menu bar at the base of this page) include:

Cronquist A 'top down' view of the Cronquist System, starting with the Class/Subclass array and links to Cronquist Subclass pages.  This system is used by our course text and the lab herbarium.
Takhtajan An entry to the Takhtajan System, starting with the Class/Subclass array that links to Takhtajan Subclass pages.
Thorne A similar starting view of the Thorne System, with the Subclass, Superorder selection and resolution to Subfamily on Superorder pages.
Informal elements of the Angiosperm Phylogeny Group system, with family listings in ordinal sequence where possible and full linkage to family placements of the other systems.
Select Family An alphabetical selection menu that leads to listings of family names with links to either Cronquist or Thorne classification systems or, for non-flowering vascular plants, direct access to internet data for the family via queries to a full text index of URLs.
Home Open this page. Handy if pursuit of family-level links (generated by selection of linked Family names) should lead far afield.

This system, designed for use by Botany 301 students and developed with funding from the Texas Higher Education Coordinating Board, is a  product of the Texas A&M Bioinformatics Working Group.  Please contact Hugh Wilson for additions, comments or adjustments.
