86 THE SUBSECTION EU-CANINEZ OF THE GENUS ROSA 
Of the oe Sasaren examples, three were collected by Briggs 
in South Dev pas an cimen from Saltash Passage, labelled 
not compoundly serrate, hairy on midribs, but only thinly so on 
side nerves. The petioles are pubescent and a good deal glan- 
dular, and bear a considerable number of small but stout hooked 
prickles. The styles are hispid, but the fruit is not formed. A 
Blackpool specimen has prickles like those of R. tomentella, leaf- 
— rather large, rounded at base, glandular-biserrate, thinly hairy 
n midrib and nerves, petioles glandular and thinly pubescent. 
Styles hispid, but no fruit as in the last. A specimen from 
between Wiverton eee lackpool was labelled R. arvatica Pug. by 
Briggs, but the leaflets are eglandular beneath, even on m midribs, 
though the petioles are glan ‘ , ne nd 
petioles are villous. The prickles are ie from large 
roundish The fruit is an bglobose, but looks 
abortive ; styles hispid. The fourth ecto was collected by 
ng » Baker at Bonington, Lanarkshire, and unnamed by him. It 
b 
rmed. The le , 
andnlar- biserrate, villous on midrib and nerves. The petioles 
are pubescent and glandular. The fruit is not formed, but the 
young calyx-tube is very elongate. Styles very hairy. 
ForEIGN Species oF SusGrovup ITI. 
Besides some of the varieties ae under R. Borrert Woods 
and Rf. cortifolia Fries, of which some individuals might be mis- 
only know of two foreign 
species likely to occur in Britain, iia, R. cnblypyla Rip. and 
fi. Guepint Desv. Neither appears to be at all common on the 
Continent, and both are treated by Déséglise as sabajeeise of 
RR. canescens Baker 
R. amblyphylla Rip. has leaflets shaped like those of R. obtws?- 
fola Desv., very hairy both sides but biserrate, flowers white or 
nearly 8 and styles glabrous. 
nt Desy. is more ~ a biserrate R. collina Jacq., with 
leaflets bibeetiali not always large, glabrous above and thinly 
meets Sisnagey Peduncles glabrous. Fruit large, subglobose, in 
Subgroup iv. Leaflets biserrate. Peduncles hispid-glandular 
or hairy.
