You should refer instead to the current version of The Plant List .

⚠ Version 1 of The Plant List has been superseded.

The Plant List contains a working list of plants of the world. The species included are grouped into 16,167 genera, 620 families and 4 major groups.

You can use the Browse function to explore the taxonomic hierarchy embedded within The Plant List .

Either work down the taxonomic hierarchy from Major Group (to find out which Families belong to each), to Family (to work out which Genera belong to each) or Genus (to find out which Species belong to each).

Or from within the taxonomic hierarchy move upwards so as to discover, for example, to which Family a particular Genus belongs.
