218 Mr. Woods on the British Species of Rosa. 



This is generally a weak stragsiling Rose, which, in the instances 

 which have fallen under my notice, docs not tiower very freely. 

 Mr. Borrer, however, — to whose accurate observations this essay 

 is in many instances deeply iH(iehted,-^tii)ds a plant in the neigh- 

 bourhood of Henfield in Sussex, which, agreemg in other respects 

 with this, is yet neither of feeble growth nor unwdhng to flower. 

 Even under this appearance the aculei are usually sHjaller and 

 weaker than in the neigh ijouring species. 



/3. has a stronger growth and larger aculei than are usual in «, ; 

 the pinnae of the calyx are also narrower, the tlowers in a 

 cyme, much more numerous; and both in appearance and 

 character it approaches very near to R. surcutosa. 



y. has a leaflet of a very dark shining green, much longer than 

 usual in R. dumetorum. I have seen very little of it, and 

 have therefore for the present joined it to this plant on ac- 

 count of the small bracteae, small aculei, weak growth, and 

 the pubescence of the leaves, which arc decidedly hairy on 

 the veins and on the surface beneath, and exhibit some scat- 

 tered hairs on the upper surface : but it must be confessed, 

 that in the shape of the leaflet and the general appearance 

 of the plant it has little affinity with this species. 



If we except the doubtful variety y, the flat leaves of this Rose 

 (a considerable portion of which in every plant is either subro- 

 tund and acuminate, or at least very much rounded at the base) 

 willdistinguish it,without reference to the pubescence, from R.sai- 

 mentacea, R. collina, and R. canina. This form and expansion of 

 the leaf it has in common with R. Borrevi and R. surculosa; but 

 the first has its leaves doubly serrated, in the latter they are al- 

 ways entirely smooth on both sides. I have already recorded an 

 observation which throws some doubt on the former character ; 



and
