The selection options
on this page, and the menu bar below, provide various paths for exploration
or comparison of three major systems of flowering plant classification.
Selection of a Family name will query an indexed file to produce a set
of web links with information on that Family or included taxa. This 'gateway'
system - eventually to include all vascular plants - is under constant
revision. Current options (base navigation bar) include:
| Browse Cronquist | A 'top down' view of the Cronquist System, starting with the Class/Subclass array and links to Cronquist Subclass pages. |
| Browse Takhtajan | An entry to the Takhtajan System, starting with the Class/Subclass array that are linked to Takhtajan Subclass pages. |
| Browse Thorne | A similar starting view of the Thorne System, with the Subclass, Superorder selection and resolution to Subfamily on Superorder pages. |
| 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. |
| Home | Open this page. Handy if pursuit of family-level links (generated by selection of linked Family names) should lead far afield. |
