When Lewis and Clark were in Montana they collected an unknown number of vascular plant specimens. Of all the specimens collected, 31 still exist and are housed in the Lewis and Clark Herbarium in Philadelphia. This page links to beautifully illustrated articles that originally appeared in the Kelseya about these 31 special Montana plants generally, species specifically, and a list of sources for further study. These articles are all PDF format.
