296 THE NATURALIST. 



Geeniee, "FZor^ de i^mnce," (1848), makes two grand sections, i. 

 ** Stipules all similar, ovaries sessile, styles free or united." This section 

 is divided into two sub-divisions, by means of the styles — free, or united 

 in a column, ii. " Upper stipules of the floral branches dilated, styles 

 fi'ee." This also includes tv/o sub-divisions — ovaries of the centre with 

 short or long pedicels. The above is Koch's method reduced to two great 

 sections. M. Grenier in his " Catalogue cles pZa»ies du Douba," (1813), 

 places the species of Rosa in a much more natural order, though not 

 dividing them into sections. 



GoNNET, *' Flore elementaire de la France" (1848), follows the divisions 

 and sub-divisions proposed by Reichenbach. 



Reuter, " Catalogue des environs de Geneve,'' ed. 2, (1861), makes five 

 sections, the three first after the persistence or decay of the calyx-segments. 

 M. Reuter neglects other characters which would have facilitated the 

 series ; thus had he attended to the prickles, the entire or pinnatifid calyx 

 divisions, to the glabrous, tomentose or glandulose leaves, he would not 

 have admitted species which he ought to have excluded. The fourth 

 section includes roses with glandulose leaves ; jB. mariglnata, Walbr., and 

 Fi,. spinulifolia, Dem., ought to be in this section and not in the Alpince ; 

 the same with F. alpestris, Rapin, which having leaves glabrous above and 

 glandulose beneath, ought not to be j^laced with the Tomentose^. 



From this account of the different methods proposed for establishing 

 sections in the genus Itosa, two of the classifications appear to merit attention ; 

 those proposed by Lindley in 1820, and by Reichenbach in 1830.^" These 



(10) I have only considered the works of those authors which I have in my 

 possession; my attempts to procure the following monographs having been unsuccess- 

 ful, viz.: — Afzelius i)e Rosis Suecards, xi. fasc. Upsal, 1804-13; Andrews Monograph 

 of the Genus Hosa, London, 1787; Rcessig Les Hoses, x. fasc. Leipsick, 1800-17; 

 Woods Synopsis of the British Species of Bosa, 1816;* Desportes Bosetum Gallicum, 

 Paris, 1828. 



* [Since writing this memoir I have received from Mr, J. G. Baker a copy of 

 Woods' Monograph of the Roses of England. Woods published this memoir in 1816, 

 in the 12th vol. of the Transactions oj the Linnean Society, pp. 159 to 234, a 

 remarkable work for the period ! Besides the very careful descriptions, there are 

 numerous observations recorded in the paper, which shew that the author had 

 carefully and attentively studied the roses of his own country. Woods formed a 

 herbarium of 133 specimens of his types, which is now deposited in the rooms of 

 the Linnean Society, at London, where they may be consulted and examined by 

 all who desire to do so. Mr. Baker has been kind enough to record in the margin 

 of the copy he sent me MS. notes relative to the authentic types of Woods, which 

 have enabled me the better to recognise the species of the English Botanist. The
