INDEX TO CURTIS'S 'FLORA LONDINENSIS ' 1775-98 

 WITH Hooker's Continuation, 1817-28. 



By B. Daydon Jackson, Ph.D., Sec. L.S. 



The following index to the Flora Londinensis was drawn up 

 in the first instance, for my own use, and the added synonyms 

 were meant for my readier access to the plates. 



Much information has been published with regard to the issue 

 of this noble work, as mav be seen in earlier volumes of this 

 Journal— vol. xix. (1881) 309-310 ; xxxiii. (1895) 112-114 ; xxxvii. 

 (1899), 390-395, the last being a detailed list, so far as was then 

 discoverable, of the sequence of the plates as issued, to the end of 

 the fifth fasciculus, with suggestions as to the last fasciculus 

 gleaned from Withering's Arrangement 1796, and Sibthorp's Flora 

 Oxoniejisis 1794. In the possession of the Linnean Society is a 

 small octavo manuscript by Dr. Richard Pulteney, drawn up in 

 or about the year 1794, styled, ' A Catalogue of some of the more 

 rare plants found in the neighbourhood of Leicester, Lough- 

 borough, and in Charley Forest,' which quotes Curtis throughout, 

 and cites the following numbers in the sixth fasciculus : — ^62. 

 Stellaria uliginosa. 63. Hydrocotyle vulgaris. 64. Lathyrus 

 sylvestris, and Ornitlioims 2^Gr2yusillus. 65. Melissa Nepeta. The 

 Lathyrus and Ornitlioims cannot both be cited as numbered, but 

 both are dated 1791, and one may have been issued earlier than 

 Pulteney's citation warrants, a clear indication for caution in 

 following such clues. 



The names given in the Curtisian Index may be found in 

 Pritzel's Iconu7n Index, but the trouble is to find the plates in the 

 book. Pritzel seems to have specially numbered the copy he 

 used, and quoted these numbers, consequently no one can find 

 his references without a long search. Similar rearrangement was 

 effected by other librarians, which I shall refer to later. 



I have followed the practice of Sir J. E. Smith, by referring 

 to fasciculus and number, but in a shortened citation, the fascicu- 

 lus being denoted by Roman numerals, as to a volume, and the 

 plates by Arabic figures. Seventy-two or 73 formed a fasciculus 

 which was closed by a triple list : (1) A catalogue of the plants 

 figured in the Linnean order: (2) an alphabetical list of the 

 Latin names, and (3) a similar list of English names. A few 

 corrections were silently made in these lists, as where Typha 

 major and T. minor of the plates became T. latifolia and T. 

 angustifolia of the index. The author's intention was to form 

 two volumes, for a general summary was given at the end of the 

 third fasciculus, and apparently only two title-pages were issued, 

 that for the first volume dated 1771, and that for the second 

 volume dated 1798, when the work was closed, but many 

 possessors seem to have bound their copies in three volumes, two 

 fasciculi in each.
