This page will allow you to look at one image of each
species within a genus (up to 24 on a page) at the same time.
Click on a family in the left-hand drop down
then click on a genus in the right-hand drop down
to see the CalPhoto images.
A list of species will appear under the site menu on the left side
of the screen. You can use the associated links to explore other
Web sites with info on the genus or individual species.
(Some of the scrolling is rather messy - especially with WTU - UW Herbarium pages [Burke Museum].
My apologies.)
