This is one of the articles of Flora Brasiliensis by Martius, written by Schumann in 1890. 69 pages of descriptions in Latin together with 25 beautiful black and white plates. Although written 9 years before Gesamtbeschreibung der Kakteen, the plant descriptions are often more detailed, and the plates are much better.
