IOS - International Organization for Succulent Plant Study

Repertorium Plantarum Succulentarum

The "Repertorium Plantarum Succulentarum" (RPS) is an annual index of new names of succulent plants, published since 1950 by the International Organization for Succulent Plant Study (IOS). Starting with volume 21 for 1970, bibliographical data is also included. The more than 50 volumes of RPS published since 1950 are in their combination the single most detailed source for succulent plant data, both nomenclatural and bibliographical, and this data is now for the first time made available for searches through SPIC.

At present, RPS is compiled by Urs Eggli (Sukkulenten-Sammlung Zürich), Reto Nyffeler (Institut für Systematische Botanik der Universität Zürich) and Daniela Zappi (Royal Botanic Gardens Kew). RPS is supplied to all members of IOS but can also be purchased separately. Most back volumes from the 1970ies onwards are still available.

Orders for RPS: Please send your orders for RPS volumes to: Sukkulenten-Sammlung Zürich, Mythenquai 88, CH-8002 Zürich, Switzerland. E-mail: . Volumes are priced ad CHF 9.00 each, and postage is added at cost.

Conventions used in Repertorium Plantarum Succulentarum

- Repertorium Plantarum Succulentarum attempts to list, under separate headings, newly published names of succulent plants and relevant literature on the systematics of these plants, on an annual basis. New names noted after the issue for the relevant year has gone to press are included in later issues. Specialist periodical literature is scanned in full (as available at the libraries at ZSS and Z or received by the compilers). Also included is information supplied to the compilers direct. It is urgently requested that any reprints of papers not published in readily available botanical literature be sent to the compilers.

- Validly published names are given in bold face type (except for epithets of new cultivars), accompanied, in the case of newly described taxa. by an indication of the nomenclatural type (name or specimen dependent on rank), followed by the herbarium acronyms of the herbaria where the holotype and possible isotypes are said to be deposited (first acronym for holotype), according to Index Herbariorum, ed. 8 and supplements as published in Taxon. Invalid, illegitimate, or incorrect names are given in italic type face. In either case a full bibliographic reference is given. For new combinations, the basionym is listed. For invalid, illegitimate or incorrect names, the articles of the ICBN or ICNCP which have been contravened are indicated in brackets (note that the numbering of some regularly cited articles has changed in the Tokyo (1994) edition of the ICBN).

- The compilers would like to point out that they do not accept any names that might be inadvertently validated in this volume of RPS.

- Bibliographic details of papers dealing only with the description of one or few new taxa are usually not repeated in the bibliographic section.

- Abbreviations for periodicals are those suggested in 'Bibliography of Succulent Plant Periodicals` (U. Eggli in Friciana 60: 1-139, 1998 ('1995) for specialized periodicals, or those of Bibliographia Periodicorum Huntianum Ed. 2 (BPH2) for most other periodicals.
