KeyBase is a dichotomous key platform hosted by Royal Botanical Gardens, Victoria, with an interface that allows one to easily navigate dichotomous keys and "filter" them with a checklist, removing key leads that do not pertain to any terminal taxa in the checklist. The Jepson eFlora dichotomous keys are fully integrated into KeyBase, essentially making a regional flora available for any of the Jepson bioregions. Select the region in which you found your plant, and you will be taken to a simplified version of the eFlora keys in KeyBase. (e.g. Key to Plants of the Sierra Nevada, Key to Plants of the San Gabriel Mountains) Taxon names in KeyBase link back to Jepson eFlora taxon pages. Get Started: NOTE: The KeyBase taxon filters are based on Jepson eFlora author's assertions of taxon ranges. As we have discovered from comparing Consortium of California Herbaria (CCH) specimen records to eFlora authored ranges in the Yellow Flag project, there are many plant populations that occur outside the eFlora authored ranges. If a filtered key does not bring you to an answer that matches the plant you are identifying, try using a more relaxed filter (e.g. use the Sierra Nevada filter instead of the Central Sierra Nevada Foothills filter), or use the full key if necessary.

The Jepson eFlora divides California into 35 ecologically distinct "bioregions" for the purpose of indicating where plant taxa grow. These divisions are grouped into regions, which are grouped into three main "provinces", as shown in the maps above. Each terminal taxon treatment in the Jepson eFlora indicates the treatments in which the taxon is asserted to occur. Using this information, a checklist for any bioregion, region or province can be made (see the eFlora Tools page for a tool that does exactly that). For full descriptions of each bioregion, see Geographic Subdivisions of California
