144 ROSE FAMILY 



dular, the outer ones with well developed lateral lobes, petals pink, flower 

 about 2-3.5 cm. in diameter; sepals deciduous in fruit, hip obovate, 

 scarlet, about 12-15 mm. in diameter : rubiginosa, rusty. 



Native of Europe, widely naturalized in the eastern United States and 

 on the Pacific Coast. Occasionally planted for its fragrant foliage. It 

 is hardy without protection in the vicinity of Minneapolis, but the longer 

 canes are apt to kill back and it seldom flowers. 



Rosa foetida H e r r m a n 1762 Austrian Brier 

 R. eglanteria of Authors (? Linne 1753) 



Shrub 6-12 dm. high, stems dark reddish brown, armed with very 

 numerous straight, strong, needle-like prickles, the longest about 1 cm. 

 long; leaves with 5-7 leaflets, fragrant, leaflets oblong, doubly serrate, 

 glabrous above, hairy and somewhat glandular beneath, tip usually broadly 

 wedge-shaped, base rounded or wedge-shaped, upper leaflets about 1.5 cm. 

 long, 1 cm. wide, petioles hairy and prickly, stipules glandular, small, 

 narrow, with acute triangular auricles; flowering shoots borne on the old 

 wood, flowers usually solitary, pedicels smooth or prickly; receptacle 

 smooth or hispid, sepals entire, glandular pubescent, petals golden yellow, 

 flower 4-5 cm. across, fruit globose : foetida, bad smelling. 



Eastern Europe and western Asia. The only form commonly culti- 

 vated in Minnesota is the semi-double "Harrison's Yellow" rose, a variety 

 of American origin, possibly a hybrid with Rosa s p i n s i s s i m a. 

 and the only yellow garden rose commonly grown in this state. It is 

 perfectly hardy without protection and ripens a large amount of seed 

 so that it would not be surprising to find it growing spontaneously m the 

 vicinity of old gardens. Flowers in early June, fruit dark reddish purple, 

 ripe in September. 



Other forms of Austrian briers would probably prove hardy lure and 

 would be useful garden shrubs. 



Rosa spinosissima L inne 1753 Scotch Rose 



Shrub 6 dm.-l m. high, branches grayish, armed with numerous 

 bristles and strong needle-like prickles; leaves with 7-11 leaflets, leaflets 

 broadly elliptical, doubly or simply sharply serrate, glabrous, and bright 

 green above, similar or slightly glandular beneath, 8 mm.- 1.8 cm. long, 

 5 mm.- 1.5 cm. wide, stipules very small; flowering shoots borne on the 

 old wood; flowers solitary, very fragrant, pedicels smooth or somewhat 

 glandular, sepals entire, smooth, petals white, or in some forms yellowish
