Kränzlin's Descriptions of orchid genera, 1880-1908. Manuscript 11Manuscript orchid diagnoses, letters, original botanical sketches, chromolithograph botanical prints, off-prints of journal articles, and leaves of printed texts, dated between 1880 and 1908, compiled by Friedrich ("Fritz") Kranzlin, in Gross Lichterfelde (Berlin),Germany, and used in preparation of his work, Orchidacearum genera et species, only 2 v. of which were published in Berlin by Meyer & Muller (v. 1 in 1901 and v. 2, pt. 1 in 1904). The bulk of the material consists of small pencil sketches or tracings of orchids on tracing paper, accompanied by Kranzlin's diagnoses, or technical descriptions in Latin of the distinguishing characteristics of the various orchid genera, following a previously-published arrangement, as evidenced by the green cloth book spines, gold-stamped with title "Orchidaceae" and vol. numbers, which are found in each bundle. There are also more detailed original drawings of orchids in pencil, or pen-and-watercolor. Accompanying Kranzlin's copious drawings and notes, are numerous prints of orchids--line-engraved and hand-colored, or chromolithographed-- by well-known botanical illustrators J.N. Fitch, Miss [Sarah Ann] Drake, and Jeanne Koch, by botanists such as Harry Bolus, and F.C. Lehmann. and by lithographers including the Belgian artist Francois Stroobant, and printed by George Barclay, Emil Laue, L. Snelling, and C.F. Schmidt. Many of these prints have been taken from botanical periodicals such as "The garden", "L'orchidophile", and "Gartenflora". There are also printed leaves from botanical texts, horticultural society proceedings, and periodicals such as "The gardeners' chronicle", and offprints of articles on orchids by Kranzlin and other botanists which appeared in journals including "Queensland agricultural journal", "Garten-Zeitung", and "Gartenflora".
