A LIST OF BRITISH ROSES

R. TOMENTOSA var. WooDsiANA H. & J. Groves, in Kept. Bot. 

 Exch. Club, 1880, p. 31. I can add nothing to my notes in B. E. 

 pp. 80-81. V.-c. 17, 32. 



R. ciNERAscENS Dum. Fl. Belg. p. 93. I have seen no further 

 specimens referable to this species beyond those mentioned in 

 B. R. p. 81. My specimen of Mr. Barclay's no. 37 may not be 

 characteristic of the whole gathering, but as three out of its four 

 fraits have respectively 3, 1, and sepals on Sept. 5th, before it 

 has even begun to colour, I fail to see how it can belong here, 

 since Dumortier says " sepals persistent till fruit ripens." It 

 also has the ovoid fruit and villous styles of B. dumosa Pug., 

 to which I would certainly have referred it, but as it has been 

 passed by Crepin, Dingier, and Sudre, it ought to be accepted. 

 V.-c. 39, 57, 88. 



GROUP TOMENTOSA. 



Most of the remarks as to the difficulties of the last group 

 apply to this one also. At the outset, we have the relative per- 

 sistence of the sepals, which is usually undeterminable from 

 herbarium specimens ; moreover, as continental botanists admit 

 suberect and persistent sepals into it, comparison with their 

 forms becomes more difficult. Further remarks are made under 

 each species. 



SUBGROUP TOMENTOSA. 



The division into subgroups is not satisfactory, but on the 

 whole the members of this subgroup have more woolly styles, 

 and more densely tomentose leaflets, than those of the next ; the 

 style characters being those I place most reliance on. Tlie sub- 

 group consists mainly of forms of the first three of the following 

 species. 



R. TOMENTOSA Sm. Fl. Brit. ii. p. 539. I am still of opinion 

 that this name is best used as an aggregate only, covering examples 

 referable to both subgroups, since Smith certainly included forms 

 of li. fcetida in it as well as forms with erect persistent sepals. As 

 it is, it merely represents a residue after segregating all the forms 

 capable of segregation to later described species and varieties. I 

 am unable to define it better, and my records only refer to such 

 residue. The resulting mixture, however, seems to be no worse 

 than that of the segregates. The species, as an aggregate, thins 

 out greatly in the southern counties, but is no doubt generally 

 distributed. V.-c. 17, 23, 27, 40, 55, 58, Perth. 



R. PSEUDO-cusPiDATA Crep. in Bull. Soc. Roy. Bot. Belg. xi. 

 p. 89." This is the plant formerly erroneously referred to B. 

 cuspidata M. Bieb. It may be taken to cover those forms of the 

 subgroup with softly pubescent leaflets, more or less glandular 

 beneath, straightish prickles, whitish flowers, ovoid fruit, and 

 hispid styles. Examples run into B. cusijidatoidcs and B. tonien-
