The Flora of Napa County, California

Updated 1/12/97

This Napa County Flora is a joint effort of Joe Callizo, Jake Ruygt, and Gilbert Muth. The three of us have been collecting data on the plants of Napa County for 30 years and what we are including in this listing are those that live here and a summary of what we know about them.

Joe Callizo is assembling the data for this flora and is putting it in a form that will be most usable for the World Wide Web. Gilbert's job is to maintain the reference herbarium and the web page. Jake is producing a hard copy version that will be available for purchase sometime in the future.

Photographs and/or drawings of the various taxa are to be added in the future.

If you discover errors in this document or know of plants growing in Napa County that are not included, we would be very happy to hear from you.
