Gravelly hillsides. Isotype. Contr. U.S. Natl. Herb. 11:353. 1906.; Lupinus piperi Robinson is a synonym of L. minimus Dougl. ex Hook. which is, in turn, allied to the L. polyphyllus-saxosus-wyethii complex. Barneby (Legume volume of the Intermountain Flora, 1990) has made major changes in the nomenclatural treatment of the elements of this complex occurring within the Intermountain region. The disposition of the Pacific Northwest elements of this group await some future student of Lupinus. - Steven Broich, Oregon St University, June 1991.
