Mary Sue and others, Just discovered that we can access the PBS wiki images and other images for comparison on the web by using Google Image Search ( http://imagesgoogle.com/ ) Images are identified to source and clicking on the image takes you to the original site. And in the case of PBS images, if you click on them it will bring up the entire PBS Wiki index. Entering a genus name or entering a genus and species in Google Image Search can bring up one or more sheets of images for comparison and search. The images can be a bit jumbled and a few extraneous plants seem to be thrown in for no apparent reason, but it is a quick way to find what is imaged on the web. Fred Boutin Tuolumne, CA
