 fruits, which are armed with stiff bristles. 



Rosa rubrifolia is very conspicuous amongst other 

 kinds by reason of its purplish foliage. For this reason

 or five feet, it may easUy be kept to two and a half or 

 three feet by a biennial pruning. The red flowers are 

 four inches across, fragrant, and freely produced. 

 Scarcely less beautiful are the scarlet apple-Uke fruits, 

 which ripen in August and September. In some coun- 

 tries the pulp is used for jelly making. A white-flowered 

 variety, alba, is also grown. Crossed with various kinds 

 of garden roses, a race of very showy roses has been 

 raised. All the varieties have fragrant flowers and are

 petals instead of five to each flower. The bush attains 

 a height of eight feet and produces its cream-coloured 

 flowers freely during April and May. A variety named 

 pteracantha was introduced from China a few years ago. 

 It is remarkable by reason of the spines being very much
