The lithograph print of Stanley's sketch of a saguaro cactus (Cereus Giganteus), a columnar cactus found along the Gila River. This print, possibly the first printed image of a saguaro, also includes a figure on horseback (Emory states that Apache frequent this area) as well as bunches of prickly pear cactus to show the gigantic size of the cactus. Throughout his reconnoissance march, Emory documented the wildlife and flora found on his journey by gathering specimens and sketches to send back to the United States to be studied and officially named. [This lithograph is from the book "Notes of a Military Reconnoissance. From Fort Leavenworth, In Missouri, to San Diego, in California, Including part of the Arkansas, Del Norte, and Gila Rivers" written by William H. Emory, opposite page 72.]
