9. R. obtusifblia (Blunt-leaved Rose). — A large bush with 

 long, arching, glabrous branches, and large hooked prickles ; 

 leaflets doubly serrate, broadly rounded at the base, glandular and 

 with prominent veins beneath ; flowers white or pale pink, gen- 

 erally with smooth stalks ; sepals reflexed and deciduous ; and 

 fruit small, sub-globose. These forms, not very sharply separated 

 from the following, seem to be local. 



10. R. canina (Dog-Rose).— Large bushes with long arched 

 branches with uniform hooked prickles ; leaflets mostly without 

 glands, or with a few on the veins beneath ; flowers few together

 falling before the fruit changes colour ; styles free. — Hedges and 

 bushy places ; abundant. This is the common Hedge Rose, a 

 flower belonging exclusively to summer, and welcomed at its first 

 appearance scarcely less warmly than the early Primrose in 

 spring. The colour of the flower varies from white to a deep 

 blush, and the leaves also differ considerably ; but the above 

 characters will be found to include all the principal varieties. — Fl. 

 June, July. Perennial. 



n. R. glaiua (Glaucous Rose), a group more locally repre- 

 sented, differs in having its leaflets often glaucous, and not gland- 

 ular beneath, and its sepals ascending after the fall of the petals, 

 and not falling until after the fruit has become crimson. 



12. R. stylbsa (Close-styled Rose). — A tall, erect bush with 

 uniform, stout, strongly-hooked prickles ; leaflets eglandular, 

 pubescent beneath ; peduncles long, bristly ; sepals pinnate, reflexed, 

 deciduous ; styles united into a central column. — Uncommon. —

 with purple branches ; leaflets glaucous beneath ; flowers white ; 

 sepals purple, slightly pinnate, reflexed, deciduous ; styles united 

 in an exserted column ; fruit sub-globose, small. — Woods and 

 hedges ; common in the south of England. — Fl. June — August.
