The American Phytopathological Society processes thousands of scientifically peer-reviewed images showing disease symptoms, pests, and other disorders associated with plants and crops through its book- and journal-publishing programs. APS images are useful for teaching, training, and diagnostics. Database is available with subscription.

The Noble Foundation Plant Image Gallery is designed to assist botanists, ecologists, natural resource managers, educators and hobbyist with the identification of plants commonly found in the southern Great Plains. The Plant Image Gallery is an ongoing project, which currently includes over 600 species of vascular plants. There are nearly 5,000 species of vascular plants known to Texas and nearly 3,000 species of vascular plants known to Oklahoma. While the plants included in the gallery are common to the southern Great Plains, a significant number of the plants included in this database may be found as far south as the Texas Gulf Coast and as far north as the Great Plains of Kansas and Nebraska. Further, many of the same species are also common from New Mexico and Colorado to Arkansas and Missouri.

The PLANTS Database provides standardized information about the vascular plants, mosses, liverworts, hornworts, and lichens of the U.S. and its territories. It includes names, plant symbols, checklists, distributional data, species abstracts, characteristics, images, crop information, automated tools, onward Web links, and references. This information primarily promotes land conservation in the United States and its territories, but academic, educational, and general use is encouraged. Over 50,000 images of plants are available.
