216 ENGLISH BOTANY. 
or less pinnatifid, generally glabrous, but sometimes with gland- 
tipped setze on the outside.* 
Mr. Baker distinguishes the following forms, which he arranges 
under four groups. 
Group I.—SUBRUBIGINOS &. 
Leaves sparingly glandular beneath, either all over or only on 
the principal veins. Pedicels naked or with aciculi. Fruit various. 
The plants of this group are placed by M. Déséglise in the 
section Rubiginosee. They appear to me to be best placed with 
R. inodora and Borreri, except R. vinacea, which appears to be a 
true Dog-rose. 
1. Rosa Blondzana. fRipart. 
Baker, in Nat. 1864, p. 103. 
Stem with divaricate branches ; prickles moderate, slightly 
curved. Leaflets elliptical or obovate-elliptical, glaucous above, 
glabrous and glaucous with scattered glands (which are most 
abundant on the midrib beneath), sharply doubly serrate, with the 
secondary serratures gland-tipped. Petioles glandular, destitute of 
hairs. Stipules and bracts glabrous, ciliated with gland-tipped 
setee. Pedicels with a few aciculi and gland-tipped sete. Styles 
thickly hairy. Fruit naked, obovate or subglobose, turning 
scarlet in September. Sepals leaf-pointed, pinnate, with gland- 
tipped setze on the outside, some of them falling by the time the 
fruit changes colour. 
In hedges. Kilvington, North-east Yorkshire; and Mr. Baker 
has gathered a very similar plant in the counties of Perth and 
Aberdeen. 
* T am indebted to Mr. Baker for specimens of the greater number of the forms 
of the Dog-roses which he has so carefully worked out and compared with Continental 
specimens named by M. Déséglise. I however feel myself quite unable to come to any 
satisfactory conclusion as to how many of the forms ought to be regarded as sub-species ; 
indeed this, as in the case of the Rubi, can only be ascertained by continued cultivation 
from seed, so as to ascertain what forms are really permanent, as it is impossible to 
determine @ priori what characters invariably descend unchanged from the parent to 
the offspring.
