The ''Index Kewensis'' (IK), maintained by the Royal Botanic Gardens, Kew, is a publication that aims to register all botanical names for seed plants at the rank of species and genera. It later came to include names of taxonomic families and ranks below that of species. The ''Index'' is currently maintained as part of the International Plant Names Index in combination with the Gray Herbarium and Australian Plant Name indexes. This database is anticipated to complete the task of creating a complete list of plant names, although it does not determine which are accepted species names. ==History== The preparation for this venture was made by Benjamin Daydon Jackson of the Linnaean Society, directed by Joseph Dalton Hooker at Kew. Charles Darwin provided the funding for the indexing project. When he died in 1882 his will stipulated that provision be made for £250 per annum over a 5 year period. In providing citations of plant names, the starting point was taken from 1753 onward; the year of publication for the ''Systema Naturae'' of Linnaeus. Darwin had found difficulties in applying these to the plants he studied, and Hooker's directive was to ‘the compilation of an Index to the Names and Authorities of all known flowering plants and their countries’.〔Hooker, 1893 Preface. In ''Index Kewensis'': an enumeration of the genera and species of flowering plants from the time of Linnaeus to the year 1885 inclusive (ed. B. D. Jackson). Oxford: Clarendon.〕 While the ''Index'' has never fulfilled this original charter, it was the most comprehensive for over 100 years. Previous attempts at a comprehensive index had relied on secondary sources, this was the first attempt to provide the original publication details of the names. A note on the country of origin was also included. The publications of De Candolle, Pfeiffer, and Bentham provided models for the acceptance of names. However, the editor admitted that not all earlier sources were included; this sometimes led to subsequent errors in botanical nomenclature. The scope of the project was also changed in early editions, the editor noting that to include a full synonymy was too ambitious. The work originally indicated acceptance of a name, acting as a nomenclator rather than an index, but by 1913 it avoided making taxonomic judgement in its citations. The integrity of the document was liable to criticism as only representing the 'Kew view' on nomenclatural validity, the objective task of indexing gave the work itself greater international acceptance.〔 A description of Hooker's systematic works by F O Bower notes the "scheme originated in the difficulty he had found in the accurate naming of plants", and anticipates the importance of this work, "Surely no greater technical benefit was ever conferred upon a future generation by the veterans of science than this Index. It smooths the way for every systematist who comes after. It stands as a monument to an intimate friendship. It bears witness to the munificence of Darwin, and the ungrudging personal care of Hooker." 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Index Kewensis」の詳細全文を読む スポンサード リンク
