The Cactaceae, Vol. 1 & Vol. 2
N.L. Britton & J.N. Rose
The Carnegie Institution


In 2006, Daniel Schweich began to reproduce in electronic format the four volumes of the book The Cactaceae issued from 1919 to 1923 by the Carnegie Institution. This is an independent project by Mr. Schweich, and the PDFs produced are entirely his effort. The Carnegie Institution's contribution has been limited to providing server space for the resulting PDFs.

Because scanning books and then interpreting and reformatting text is labor-intensive and imperfect work, mistakes may have been introduced, and thus

the Carnegie Institution and Daniel Schweich are not responsible for the content of or any errors in these files.

However, anybody who finds errors or misprints or wants to comment on the files is welcome. You may contact Daniel Schweich at

Please send e-mail only if really necessary!
