The Missouri Botanical Garden recently released an electronic version of Hermann A. Kohler's 1887 magnus opus, Medizinal-Pflanzen, a three-volume set of "plants of medicinal interest from several European nations." Over 270 chromolithographic illustrations have been digitized from slides and included in this browseable site. The Tour of Illustrations section leads the visitor, one by one, through individual illustrations from the book. Each illustration is labeled with the family name at the top and the scientific (Latin) name at the bottom of the page. Following this is a section of thumbnail images of the illustrations, each of which is linked to a larger illustration. The final section contains an alphabetical list of scientific names, each name being linked to a full page illustration. Common names are not given, nor is there a search function at this time.
