 Gt. 24:846. R. rugosa is one of the most ornamental 

 Single Roses, especially for shrubberies ; it is very hand- 

 some on account of its dark green shining foliage, large 

 fls. appearing during the whole summer, bright red con- 

 spicuous fruits, and its beautiful orange and scarlet fall 

 coloring. It is also attractive in winter by reason of its 

 stout, densely armed stems. Large numbers of hybrids 

 have been raised. By crossing with double-fld. Garden 

 Roses R. rugosa has given rise to a new race of hybrid 

 Roses remarkable for their hardiness and long blooming 

 season; one of the best known is Mme. George Bruant 

 (Fig. 2165), with double white fls., a cross of R. ruqosa 

 and the Tea Rose Sombreuil. Another cross with a form 

 of R. Chinensis is R. rugosa, var. calocarpa, Bruant, 

 with single rose-colored fls. and handsome fr. produced 

 very abundantly. Gn. 46, p. 548; 52, p. 384. R.H. 1895, p.

 there are probably others.
