"The Calflora Database contains information on 7500+ ferns, conifers and flowering plants known to be native or naturalized in the wild in California. Our species database also contains 700+ records for species-level plants (so called "parent" records) where two or more subspecies occur in California, bringing the total number of taxon records to more than 8000. Parent level records include characteristics from all "child" subspecies.
Our basic search form allows you to search by family name, common name, scientific name, county, elevation range, growth form, native status, rarity status, plant community, and more."

"What Grows Here is a new Calflora project which emphasizes what plants have been observed growing near a particular place. Through this interface, users can pick a place in Calfornia by any of several different approaches (eg. by town, zip code, watershed, park etc.). Results are displayed in a list (with or without photos), and as points on a relief map."
