Ex Milton College Herbarium. Permanently transferred to WIS in 1982. This collection consisted largely of specimens donated by or purchased from Mr. S. H. Watson, whose collections were made in southern Wisconsin from 1859-1862. The Watson collection contains some specimens received from fellow Wisconsin botanist T. J. Hale and a few other collectors, including I. A. Lapham, D. C. Eaton, S. B. Mead, and M. H. Clark.
