Loeraci: Literis S. A. de La Carriere, 1747. Contemporary calf. Two parts in one. 8vo (18.0 x 10.0 cm). Contemporary calf with raised bands gilt “fleur-de-lis” in panels; red leather label; wear and some loss to corners and fore edge of upper board. Collation: [xiv], 224 pp.; 14 [2- Corrections and Eratta] pp. Red edges; marble end papers; text has occasional minor spotting and soiling. The two parts in this fine catalog contain lists of plants growing in the Royal Gardens and Orangerie at Carlsruh. The first part lists plants that Christian Thran, main gardener, had recorded in his diary. In this section the plants are separated into Exotic plants (Plantarum Exoticarum in Hybernaculis Adserv andarium), Perennial plants (Plantarum Perennium) and Annual plants (Plantarum Annuarum). Plants in each section are numbered and this system is maintained throughout for a total of 2,993 plants in the main garden. There is no change in the numbering. Within each section the plants are listed alphabetically and each genus and species is referenced for literature citation(s) with author, publication and page where described.
There is separate section in the preliminary pages that contains the shorthand used by Risler for author citations. There are only three early publications by Linneaus cited since Species Plantarum was not published until 1752.
The second part has a half-title page, Catlaogus Malorum Aurantiorum, Citreorum & Limonum vulgo Agrumi Dictorum HORTI CAROLSRUHANI. The text for this work contains listing of all citrus fruit growing in garden at Carolsrhuh, most likely in the Orangerie. The text under the heading Agrumi Horti Carolsruhani is organized into alphabetical sections that have separate sequential numbering of species for each:
A. Aurantia cortice & medulla dulci eduli. sp.1-7; B. Auratia, cortice amaru & medulla dulci. sp. 8-12; C. Aurantia, cortice amaro & medulla acri. sp. 13-34; D. Citrea, fructu acido. sp. 35-40; E. Limones, fructu acido, sp. 41-44; F. Limones, fructu dulci. Sp. 45-51; G. Limones, fructu acido & aliae species. sp. 52-85; H. Quum Agrumi sequentes nondum fructificarint… Quare ferie Alphabetica separatism recenfentur. Aurantium, sp.86-93 &; Limon, sp. 94-151; Aurantium sp. 152-154. Within this list there are 6 unnamed Limon species. Most of both Aurantia and Limon species have reference citation, principally to second volume of Volkamer’s 1708 publication Hesperides Norimbergenses. There are 12 Aurantia and 27 Limon species for which no reference is cited. Very good. Item #0000806
Christian Thran was the gardener for margrave Karl Wihelm of Baden-Durlach from 1731 to 1746 who asked him to create the palace garden in the French baroque style. (Castles of Karlsruhe & University of Karlsruhe). Thran kept a diary of his work as head gardener and is responsible for the list of all the plants. In his Preface Josua Risler explains that the council (overseeing the garden?) ordered this publication, requesting him to check Thran’s list and add literature citations. This made the list more usable by any reader, particularly as the references cited often had illustrations of the plant of interest to the reader. Risler was also asked to prepare the second section on citrus fruits complete with references. These plants were probably not covered in Thran’s diary. Also, the citrus plants would most likely be in the Orangerie.
It is understandable that Josua Risler, a pharmacist, prepared the list of all the genus and species of citrus fruit growing in the Carolsruh Orangerie. He would be most familiar with citrus fruit, as well as being knowledgeable of botanical literature to add proper citation to all the plants. The exception, as noted, is for a number of citrus species for which bibliographic reference is lacking. It is possible that these citrus plants were known to Risler, as they would have been in the German pharmacopeia of the time, possibly added from voyages, plant explorations or described in other publications unknown to him (Pritzel, 7369).
