Plate 71, Iconographic encyclopaedia of science, literature, and art. / Systematically arranged by J.G. Heck. Translated from the German, with additions, and edited by Spencer F. Baird ... illustrated by five hundred steel plates, containing upwards of twelve, 1851

This object is not part of the Cooper Hewitt's permanent collection. It was able to spend time at the museum on loan from Smithsonian Libraries and Archives as part of Botanical Lessons.

This plate comes from an illustrated encyclopedia organized by German publisher and author Johann Georg Heck, in his 6-volume effort to comprise and organize knowledge of science, literature, and art in an accessible format. Figure 4 here depicts a walnut tree and figure 7 presents a variation of buckthorn, both of which are represented in corresponding botanical models on view in the central case nearby.

This object was previously on display as a part of the exhibition Botanical Lessons.
