The U.S. National Herbarium has begun a rapid digitization project, starting with the digitization of plants specimens in the family Onagraceae (evening primrose). Onagraceae has developed over the past half century as a model system for the study of plant evolution. At present, systematic revisions are available for virtually the entire family of 660 species in 22 genera. Molecular phylogenetic analyses have resulted in a major new classification of the family with a comprehensive monograph completed in 2007 by Warren Wagner and collaborators. Once imaged and databased, the herbarium’s collection will provide more than 25,000 specimen records across the family to be utilized in tandem with ongoing research projects world-wide. Over 130 species are rare or endangered, including the narrowly endemic Oenothera riskindii, known only from montane open oak woodland in Rincón de María and adjacent Serranias del Burro in northern Coahuila, Mexico (Syst. Bot. 30: 332-355; 2005). The published plate of Oenothera riskindii consisted of four separately inked drawings assembled in Photoshop. The drawings were displayed at the Desert Botanical Garden in Phoenix, Arizona from April 2006 - May 2007 for the exhibit, “Botany Beautiful: The Tradition Continues.”
