HAB. Bunks of the Dee about Abergaldy, Mr. duderson, in Linn. 

 Trans, vol. xi. p. 244. FL July. J? 



" Branches erect, reddish, 3 4 f. high, covered all over, as for as their 

 extremities, with nearly equal weak bristles and prickles. Stipules 

 dilated towards their extremities, eroded at the edge, fringed with 

 glands, naked ; petioles sparingly glandular, without hairs as are 

 the leaflets, whiclt are 7 11, almost flat, oval, pointed, simply 

 serrated or nearly so, dark green above, paler beneath. Flowers 

 solitary without bractese, pale or deep red j peduncles hispid ; tube 

 of the calyx less so ; segments of the calyx erect, entire, rough, shorter 

 than the petals, which are concave and emarginate $ disk not thick- 

 ened. Fruit pendulous, long, ovate, scarlet, crowned by the con- 

 verging, shorter segments of the calyx." L. The stems and branches 

 covered with bristles and a few prickles, together with the red pen- 

 dulous fruit, distinguish this species from R. spinosiss. At the same 

 time I must remark that Mr. Lindley's <e var. p . mclanocarpa fructu 

 nigro fusco breviore" is, as he himself says, just intermediate be- 

 tween R. rubella and spinosiss. 



whole genus has been subjected to by my friends, Mr. Jos. Woods and Mr. 

 Liudley, whose two valuable Monographs, the former of the British species 

 in the \'2th vol. of the Linn. Trans., the latter in a most excellent work en- 

 titled Rosarum Monographia, have set in a comparatively clear light what 

 was before a mass of confusion. Doubts will still remain as to what are 

 species and what are not. I must confess that I give the preference to the 

 characters and arrangement of Mr.Lindley ; and, conscious that I could offer 

 no original remarks or descriptions of equal importance to his, I conceive 

 that I am doing an acceptable service to the student of the Scottish Roses in 

 giving all that relates to the genus in Mr. Lindky's own words. 



It will be necessary to say a few words on the terms employed by Mr. 

 Lindley, and the degree of importance he attaches to the different parts. 

 " Arms is a term used to express the presence of bristles and prickles indis- 

 criminately. 



Bristles (sctce] are little straight prickles, tipped with a gland, and known 

 from real glands by their rigidity, greater length, and tendency to pass 

 into prickles. They exist probably on all species upon the roots/toots, but 

 are quickly changed into prickles by losing their gland. On their pre- 

 sence depend some of the most natural divisions. On the fruit and pe- 

 duncles, however, they are found to be of little value ; for in R. rubiginosa 

 and tomentosa setigerous and naked fruit is borne even on the same bush. 

 They vary too on the fruit and peduncles of R. canina and sjrinosiss., but 

 appear constant on R. involuta, Sabini, and villosa. 



The form of the prickles (aculei) distinguishes the Div. Canince from J^llosce ; 

 and their inequality separates the Rubiginosa from the former. They are 

 variable and not to be depended upon on the petioles. 

 Glands are distinguishable by their scent, and are mostly attached to the 



underside of the leaf as in the Div. Rubiginosa. 



Pubescence on the branches, peduncles or tube of the cat. is considered by 

 Mr. L. an invariable character j but it is of little or no consequence on the 

 leaves. 



The tube of the calyx and the fruit can in few instances be employed in 

 forming distinguishing marks. All varieties of form may be found in 

 R. canina and tomentosa. 



All the Roses yet known are found between the 19th and 70th degrees of 

 X latitude." L.
