A LIST OP BRITISH ROSES 49 



E. sYLVicoLA D^segl. & Eip. in M^m. See. Ac. Maine & Loire, 

 xxviii. p. 122. I have seen no further specimens of this beyond 

 those mentioned in B. K. p. 121. V.-c. 27 '?, 31. 



GROQP ELLIPTICA. 



The members of this group correspond to those of the Eglan- 

 teria group in their erect, compact growth, and more or less 

 spreading-erect, subpersistent sepals, but differ essentially in 

 their leaflets being decidedly wedge-shaped at the base, and their 

 peduncles smooth ; their styles also are usually more hairy or 

 villous. 



E. BiLLiETii Pug. ex Cr6p. Prim. Monogr. i. p. 337. This is 

 distinguishable from the next by its more hairy and more glandu- 

 lar leaflets, ovoid fruit, and less villous styles. I think the Brean 

 Down plant referred to under B. inodora Fr. in B. E. pp. 125-7 

 comes very near this on account of its densely hairy styles and 

 other characteristics, though it has not hairy peduncles, which is, 

 however, not a character of much constancy in the genus, more- 

 over, the Bridport specimen of B. Billietii has them glabrous. 

 V.-c. 6?, 38. 



E. CRYPTOPODA Baker, Eev. p. 22. I have seen none but the 

 Luddenden specimen of this, but not only is there some uncer- 

 tainty as to whether that specimen really represents B. crypto- 

 2)ocla, but it is doubtful whether that species is correctly referred 

 to this subsection (see B. E. p. 112). V.-3. 63 or 64. 



GROUP AGRESTIS. 



This bears the same relation to the group Micrantha that 

 Elliptica does to Eglanteria, in its members having their leaflets 

 decidedly narrowed at both ends, and smooth peduncles. Their 

 tali lax habit and glabrous styles resemble the Micrantha group. 

 Next to that of Elliptica it is our rarest group, and only occurs in 

 a few of the southern and western counties. 



E. AGRESTIS Savi, Fl. Pis. p. 475. Though I have kept this 

 distinct in my British Boses from B. sepiuvi Thuill., I think it 

 is more satisfactory to unite them, B. sepiiim being only a larger 

 form. It appears to be quite rare in Britain, most of our forms 

 of the group having larger leaflets, even than B. sepium, and more 

 or less pubescent instead of quite glabrous, as in the type. A 

 specimen from N. Somerset (Marshall) may be placed here. It 

 was referred to var. elegans Eouy by both Sudre and Dingier, 

 presumably on account of some apparent hairiness of the leaflets, 

 but the hairs consist of thistledown and sheep's wool, tlie leaflets 

 being really quite glabrous. A specimen from S. Hants (E. F. 

 Linton) also probably belongs here, the leaflets being all but 

 glabrous, though they are as large and broad as is usual in var. 

 suhcuneata. There is also tlie Puttenham, Surrey, plant (Groves),
