Do you know of any good web sites that provide keys for the identification of native plants? I'm conducting a wetland plant inventory in southwestern Ohio.
North Carolina State University has a web site Wetland Plant Identification with dichotomous keys for woody vines, parallel-veined plants, gymnosperms, and trees and shrubs. The web page also offers the option to search by plant characterisitics such as leaf arrangement, leaf structure, axillary bud type, etc.
From the Univeristy of Wisconsin Herbarium at the Cofrin Center for Biodiversity there is a web page, Wetland Plants of Wisconsin, with pictures of leaves, flowers, fruiting heads and more for approximately 110 common wetland species.
There is a sample of an interactive software program to purchase for PCs using Windows 95 or higher to help in identifying 1,000 Weeds of North America
The University of Florida has a web page Aquatic and Wetland Plants and Invasive Plants with photographs and descriptions that can be searched by scientific name, common name or plant type category (grasses, ferns, sedges, rushes, etc.).
