2015 site revision prototype.

Nels Lersten has retired from teaching and is cutting down on his research schedule. John Curtis plans to do the same very soon. Between the two of us we have over 60 years of plant anatomy teaching and research experience. We felt it would be a shame if the thousands of plant anatomy images we have taken for teaching and research were to retire with us. Therefore, we have put many of these images on this website with free access given to anyone interested. We have made no effort to give a balanced treatment of anatomy topics although most topics are represented. Because much of our research has been on plant secretory structures, this set of image reflects that bias. We hope that these images will be useful to people teaching (and taking) plant anatomy and related courses.
