ROSA RUBIGINOSA. L. Sweet Briar. Eglantine. 



Fruit obovate, fruit and peduncles hispid ; prickles 

 hooked ; leafets oval, with reddish glands beneath. 



Stem from three to four feet high, the younger ones reclining 

 at top, the old ones much branched, armed with strong, hooked 

 prickles. Leaves pinnate, with oval serrate leafets, which give 

 out an agreeable, strong scent on being rubbed. The under sur- 

 face in most plants is slightly glandular, though less so than 

 in the European sweet briar. Flowers red. Fruit scarlet, 

 somewhat obovate, bristly or smooth. Road sides. June. In- 

 troduced. 

 ROSA MICRANTHA. Sm. Sina II flowered Sweet Briar. 



Fruit ovate ; fruit and peduncles somewhat hispid ; 

 prickles hooked ; leafets ovate, acute, with reddish 

 glands beneath. 



This species is more common than the last, which it resem- 

 bles in the odour of its leaves. It is a larger bush, being fre-

 size of the former. Common in dry soils, road sides and pas- 

 tures. June.

Germs globular, hispid ; peduncles somewhat his- 

 pid ; stem with stipular prickles : petioles prickly. L.

 and size of their prickles, even those which spring from the
