4 Bailey, Herbariitm of British and Foreign Plants. 



by H. C. Watson, in his "Topographical Botany"; while the 

 Irish localities follow the divisions of the Irish flora adopted by 

 D. Moore and A. G. More in their " Cybele Hibernica." A 

 nearly complete set of plates contained in the second edition of 

 Sowerby's " English Botany," is included in the herbarium, as 

 well as the plates of " Fryer's Potamogetons," " Hanbury's 

 Hieracia," etc. 



Some attempt has been made to catalogue the contents of 

 the British portion of the herbarium, but a busy life has not 

 lent itself to furthering this intention. Whether I shall have 

 the time to do so now is doubtful. One volume only has been 

 compiled, bringing up the data to the end of the Caryo- 

 fhyllacece. 



A record has been kept of every British plant which I have 

 collected during the last fi.fty-fi.ve years, the entries being con- 

 tained in two volumes, of foolscap size, lettered, " Dated Col- 

 lections of British Plants," Vol. I. being from 1862 to 1898, and 

 Vol. II. from 1899 to the present time. The plants have been 

 entered in the exact sequence in which they were gathered, the 

 use of a collecting book in place of a vasculum facilitating 

 this arrangement. At the end of every year a systematic sum- 

 mary is given of all the British gatherings of the year. 



In the Continental portion of the herbarium the species 

 stand in the exact order of Nyman's " Conspectus," and their 

 position is shown by the numbers stated on the outside of the 

 boxes; thus, box 1,825 contains Achillea, species Nos. 18 

 to 20, on page 368, viz. : — Achillea Gerberi, M.B., A. micranthuy 

 M.B., and A. le-pio-phylla, M.B. A copy of Nyman's " Con- 

 spectus " is marked with the corresponding numbers of the 

 boxes, and of their contents. Nyman's index of species would 

 have been greatly increased in usefulness if the names of the 

 authorities for the species had been given ; their absence necessi- 

 tates the making of an independent index for all the larger 

 genera. Nor does Nyman print at the beginning of each 

 page the name of the genus indexed, a fact which often 

 renders the references very irritating, and time consuming. 



When the species, native or cultivated, belong to a genus or 

 species not included in the "Conspectus," a place has to be 

 found, by intercalating such plants according to the position 

 assigned to them in Bentham and Hooker's ''Genera Plantantin'^' 

 (London, 1 862-1 883), as summarised in Th. Durand's "Index 

 Generum Phanerogamerum " (Bruxelles, 1888). Use has also 

 been made of De Candolle's "Prodromus"; Ascherson and 

 Graebner's " Synopsis der mitteleuropaischen Flora " (Leipzig, 

 1896-1913); Richter and Gurke's " Plantas Europaeas" (Leipzig, 

 1890-1903); Boissier's "Flora Orientalis " (Geneva and Basle, 

 1867-1888); W. D. J. Koch's "Synopsis der deutschen und 

 Schweitzer Flora" (Leipzig, 1890-1906); Rouy's "Flore de 

 France," Vols. I.-XIV. (Asnieres, 1893-1913); Willkomm and 

 Lange's "Prodromus Florae Hispaniae " (Stuttgart, 1870-1893);
