178 THE NATURALIST. 



as, indeed, it is on almost every other of British botany. It has occurred 

 to me that the Naturalist would be a fitting recipient for such a list, and I 

 shall therefore, with the Editors' permission, send portions of it from time 

 to time, for insertion in its pages. The list will contain the following 

 particulars relative to each plant enumerated ; — its locality, the name of 

 the person by whom it was noticed, and the date, when this is attainable, 

 of its discovery ; with such notes as may appear to me useful or interesting 

 relative to the circumstances of its occurrence. I shall be very much 

 obliged to any of the readers of the Naturalist for any information which 

 they can supply regarding such plants, and when accompanied with speci- 

 mens this will be the more acceptable. The list will be in accordance 

 with the fifth edition of the London Catalogue ; the species which are there 

 admitted will find no notice here, and this, not because I accept the 

 dictates of that work, but because it is absolutely necessary to have some 

 list as a guide as to what to exclude, and what to embrace, and the London 

 Catalogue being cheap and well known, is chosen in preference to other 

 more elaborate works. 



In addition to those plants which I have termed '' spontaneous exotics," 

 there are others which, although British species, cannot possibly be indi- 

 genous to many of the localities in which they occur ; these must, however, 

 be left unnoticed at present. There are also some species which are set 

 down as " erroneously recorded," &c., of these I shall give such particulars 

 as may be deemed useful for reference. Of the few species, new and 

 apparently indigenous to Britain, which have been discovered since the 

 publication of the fifth edition of the London Catalogue, I shall here take 

 no notice, as I could not include them with propriety under the title which 

 I have chosen for these papers ; and for the same reason the recent divi- 

 sions of the species of Fumaria, Papaver, &c., will be excluded. After the 

 completion of the present list, a supplementary one will be given, in which 

 will be recorded such additions, whether of species or localities, as may 

 have occurred since the present date. 



The following are the principal works hereafter quoted or re- 

 ferred to, with the abbreviations by which I have distinguished them for 

 reference : —
