The herbarium collection records upon which the Wildflower Search programs are based have been produced by the work of tens of thousands of people working over the last century. Most of these records are provided only for non-profit applications and many come with a creative commons license. The number of people involved is too large to mention each by name. But the institutions involved are listed below.
