126 ROSACEA. 



V. Brixton Torr. Near Goodamoor, and between Liitton and 

 Sparkwell. 

 This well-marked Bramble was considered by the late Rev. A. Bloxani 

 identical with the R. ohliquus of Wirtgen. (See Jour. Bot. viii. 69, 70.) 

 An examination, however, of a specimen of the latter in ]Mr. Baker's 

 Ilerharium some years ago led me to a different conclusion. In the same 

 collection of Rubi were specimens of R. mutabilis, Genev., and I found 

 the Plymouth plant so much Hke these that I shortly after ventured to 

 assert its identity with this species of M. Genevier, in an article con- 

 tributed to the Journal of Botany (vol. ix. 368-70). I have since been 

 nnich pleased to find Babington supporting my conclusions on the matter 

 in his very valuable 'Notes on Rubi' in the same journal. (See vol. vii. 

 N.S. 143, 44.) From them I extract his description of this Bramble : 

 "i2. mutabilis, Genev. ; stem arcuate-prostrate angular, sparingly pilose 

 and setose ; prickles moderate unequal, sub-patent from a long compressed 

 base ; aciculi strong, very unequal, mostly short ; leaflets rugose above, 

 doubly and mostly lobate-dentate, very densely hairy or felted beneath ; 

 terminal leaflet obovate-acuminate ; basal leaflets stalked, not imbricate; 

 2xtnicle long narrow-i)yramidal, leafy nearly to the top ; its branches 

 and branchlets subcorynibose suhjmtent ; its rachis very jynckly, adcn- 

 late, and setose ; its prickles very strong from large compressed bases, 

 numerous ; sepals ovate felted, setose retiexed with rather leaf-like 

 pomts." The petals are dull white ; filaments white ; styles greenish. 

 The fruit is symmetrical, well-flavoured, and abundantly produced. The 

 stems have often a glaucous bluom. Babmgton would place it between 

 R. diversifolius and Lejeunii, the arrangement I have followed here.
