Dear James, I agree, it does seem to key out best to D. discolor, but that is a plant of the low (Sonoran) desert, several mountain ranges and many hundreds of miles away from here. There are some Daturas that occur in less remote areas, but I have never known of any to grow in the San Francisco Bay area. But if Annie's (an hour's drive and only a bay away from here) grows D. discolor, then seed can be nearby. Thanks for your response, David E.
