Nels Lersten and John Curtis, his student, were involved in plant anatomy teaching and research for more than 60 aggregate years. In the transition to retirement, it has been their intent to make images from their work available without restriction to other teachers and students of plant anatomy. Michael Nowak, a third generation student of John Curtis, was primarily responsible for implementing the website. Since 2002, the University of Wisconsin at Stevens Point has generously provided support and technical assistance for this unique academic resource. Most elements of plant structure are represented in this atlas, but the image set does reflect Lersten’s and Curtis’s research emphasis on plant secretory structures.
