U. S. Department of Agriculture,
Washington, D. C., June 5, 1891.
Sir: I have duly prepared by your direction a descriptive list of the more important economic plants at present contained in the collection of the Department, in such a form as will, in my opinion, most satisfactorily meet the wants of the numerous visitors and others interested in the work performed by the Department in this direction, and I beg to submit the same herewith for publication.
