Mr. Woops on the British Species of Rosa. 181 
are represented as all equal; and being variously bent, look 
rather like hairs than prickles: their length, however, gives them 
a different appearance from those of R. rubella, and I have never 
observed smooth fruitstalks on that species. In all the Roses of 
the llora Danica there is an unnatural curvature and laxity of 
habit, which was probably introduced by the artist from the no- 
tion that it would render them more beautiful as drawings. 
No small degree of confusion bas arisen between the names of 
R. spinosissima and R. pimpinellifolia, originating apparently witli 
Einnæus himself. In the Flora Lapponica he says of R. sylvestris 
pomifera minor, which has usually been considered the same as 
R. spinosissima, * In desertis passim prope tuguria vel fluviorum 
ripas obvia fuit, licet nullibi copiose." In the Flora Suecica he 
describes a species under that name, with a reference to the Sp: 
Plant. but not to the Flora Lapp., and says of it, ** Habitat ad 
agrorum margines, eorumque acervos passim." Again, in the 
Fruticetum Suecicum (Amen. Acad. v. 220,) he writes, ** Per totam 
Sueciam crescit, precipue in acervos lapidum et ad agrorum mar: 
gines, adeoque in sabuletis et montibus." In the second edition 
of the Sp. Plant. i. 703, R. pimpinellifolia is first introduced, “ ger- 
minibus globosis, eaule aculeis sparsis;" and it is added, “ Habitat 
forte in Europa:" but nosynonyms are given. In the same edi» 
tion R. spinosissima is described. “ germinibus ovatis glabris, pe- 
dunculis caule petiolisque aculeatissimis ;" and in the Syst. Veg. 
edit. 13, the character “ germinibus globosis" is equally given to.

Sir J. E. Smith considers the specimen of R. pimpinellifolia in 
the Linnzan Herbarium as undoubtedly R. spinosissima ; and very 
naturally concludes, that when Linnæus added R. pimpinellifolia; 
he did not recollect the plant to which he had previously given 
another name. Dr. Wahlenberg, Fl. Lapp., quotes R. spinosissima 
of Fl. Suec. of Linnzus, but with a mark of doubt, as a pue
