Camissonia's CA Native Plant Life List

I"ve been an amateur botanist since circa 1997 with a special interest in California native plants. A corollary passion of mine is birding and, like many fellow birders, I keep a Life List of all the bird species that I've observed in my lifetime. So I thought, why not also create a life list for plants I've seen in the field? In addition to California natives, I've also included a smaller list of plants that I've observed and photographed in their native habitats outside of the U.S.
