The US boundary commission was involved both in boundary demarcation and mapping and in natural sciences. From 1848 to 1853-55 the US-Mexican boundary territories were studied in details, and the results were published by one of the commissioners, William H. Emory, in a report entitled ”United States and Mexican Boundary Survey” (Vol. I in 1857, Vol. II in 1859).

Volume II, part II of the report deals with botany, and one chapter is devoted to cacti. There were official plant collectors (Bigelow, Parry, Schott, Thurber, Wright) and some freelance collectors (Berlandier, Fendler, Le Conte, Lindheimer). George Engelmann had then to study the collected material and to write the chapter devoted to cacti. The result is made of about 70 pages of accurate cactus descriptions illustrated by 75 extraordinary B&W plates (read carefully ”explanation of plates” and ”corrections”).

Right: George Engelmann.

"Report on the botany of the expedition"

From 1855 to 1861, the US government published the ”Reports of Explorations and Surveys, to ascertain the most practicable and economical route for a railroad from the Mississippi River to the Pacific Ocean, made under the direction of the Secretary of War, in 1853-4”. Besides the topographic considerations, this report conatins a lot of fascinating information about geology, zoology, botany and ethnography 3).

The 3rd item of Volume IV, part 5 is devoted to cacti. It was published in 1856 and contains 31 pages of descriptions and 24 B&W plates (mainly Opuntia). The text contains a lot of typographical errors, however there is a long list of corrections at the end. The proposed files are made from the material of Botanicus which is annotated by Engelmann himself who added further corrections. The Original file is a copy of the annotated original. The interpreted file is the corrected text.

The complete part 5 devoted to botany can be downloded from the Biodiversity Heritage Library (BHL)4) under mobot31753000823119.pdf5) (19 MB).
