Current Projects: Indiana Plants Electronic ID Guides
These are PDFs that users can download to PDF readers on their smartphones, iPads, or other electronic tablets, or they can be printed out and put into a 3-ring binder. The aim is to provide information for identifying Indiana plants that can be carried into the out-of-doors. Currently, there are two types of PDFs: (1) Character ID Guides and (2) Indiana Species Pages.

The Spring Wildflower Finder is a 4-page PDF with 112 image pairs of flowers. These are arranged by color and each color section is arranged from largest to smallest flower (measurements listed are for petal or corolla length). This version of the Spring Wildflower Finder contains images for 56 of the approximately 300 wildflower species that come into bloom in Indiana in February through April. Wildflowers are considered to be all flowering herbs except grasses and sedges, plus small woody species that do not have the typical shrub form. The scientific names of native species are listed in italics; non-native species are in italics plus small caps.

Each Indiana Species Page is an image-rich 8 1/2 × 11-inch PDF with images of the flowers, the inflorescence, the leaves, the whole plant, and close-ups of details necessary to distinguish it from other similar species. Text is minimal and includes measurements for the plant and its parts. A county-level Indiana map is included.
