GROUP OF ROSA CANINA. 25 
No. 27, which — refers to the R. Blondeana group, is quite 
glabrous, while Briggs’s specimens are quite hairy on the side 
nerves), inconspicuously glandular on the midrib and sometimes 
also on the secondary nerves. Fruit ovoid-ellipsoid; sepals 
spreading ; 4 styles glabrous, or nearly so 
A lan coll se at Puttenham by Groves, and labelled “ R. 
sepium,” is siehs d to R. arvatica Puget by Déséglise, no doubt cor- 
rectly, as it clearly belongs to R. sepiwm and not to R. tomentella. 
FOREIGN AND ALLIED SPECIES. 
The only foreign species known to me of the Tomentella group 
which might be found in Britain is R. similata Pug. It has the 
rickles and small broad biserrate ce glandular beneath, of 
f. tomentella, but the peduncles, and often the base of the fruit, 
are strongly hispid- glandular; the at ct is ellipsoid, and the 
styles glabrous. 
Of British varieties a do not think any are likely to be mis- 
taken for varieties of R. tomentella, except some of those classed 
under f. Siriafolal Fr. Of these R. Watsoni Baker, R. Bakert 
Déségl., var. ncana Woods, sual var. Lintoni Scheutz have the 
leaflets ee or less glandular beneath, but whey. may all L 
lon, to the coriifolia grou their woo iy

GROUP OF ROSA CANINA. 
The description by Linneeus of Rosa canina in Species 
Plantarum i. p. 491 (1755) is—* Rosa caule aculeato sepa iner- 
mibus calycibus avi seer ” In ed. ii. p. 704 he has—* Rosa 
erminibus ovatis pedunculisque glabris, caule petiolisque acu 
eatis.” The description in the “ Mantissa,” p. 391, is a little 
fuller, viz. :—*‘ Caulis levis, internodiis aculeis 2 alternis. Petioli 
aculeati. Folia acutiuscula wre Pedunculi glabri. Germen 
glabrum. Petala pallida vel in 
The only other British spell described by Linnezus are 
R. villosa, R. rubiginosa, R. arvensis, R. pimpinellifolia, om 
wi cles, 
ovoid fruit. The older British botanists applied the name “ Rf. 
canina L,” to plants with either fully biserrate or uniserrate leaflets. 
Déséglise, in the preface to his py A “Raisonné, pp. 17-21, 
quotes some notes received by him from Mr. Baker on _ Roses 
of Linnzus’s herbarium, who says ‘of No. 25 R. ca 
herb.: “Exactly BR. lutetiana Lém. Toothing See ; pukiolan 
with 3-4 recurved prickles, but neither villous nor re 4 
stipules lightly glandular-ciliate ; satin les naked ; sepals m 
pinnatifid and strongly glandular-ciliate throughout their whol 
length.” I have seen this n and should describe t
