The staff of the Wisconsin State Herbarium have created this excellent online resource for exploring the world of vascular plants in Wisconsin, complete with several helpful finding aids to navigate the collection. Based on decades of research (including the ground breaking work of John Curtis), visitors can search for plants by name, habitat, status, and county. Also, visitors to the site can browse the thousands of selections by genera, common name, and family. A wealth of information is included about each plant, including (in most cases) a photograph of the plant in its habitat, a map indicating where the plant may be found in Wisconsin, and its common names. Other features of the site include a guide to "What's Blooming" around Wisconsin, a key to the conifers of Wisconsin, and information about other current projects of the Wisconsin State Herbarium.
