FLOWEEING TREES AND SHRUBS 167 



R. BANKSI^S (China, 1809) is a desirable species, with 

 numerous small, nodding, double-white, scented flowers. 

 It will climb to 20 feet in height. 



R. BRACTEATA (Macartney Rose), R. PALUSTRIS (Marsh 

 Rose), and R. MICROPHYLLA (small-leaved Rose), belong to 

 that section supplied with floral leaves or bracts, and 

 shaggy fruit. They are of compact growth, with neat, 

 shining leaves, the flowers of the first-mentioned being 

 rose or carmine, and those of the other two pure white. 



R. CANINA. Dog Rose. Our native Roses have now 

 been reduced to five species, of which the present is one 

 of the number. It is a straggling shrub, 6 feet or 8 feet 

 high, and armed with curved spines. Flowers sweet- 

 scented, pink or white, and solitary, or in twos or threes 

 at the branch tips. There are many varieties. 



R. CENTIFOLIA. Hundred-leaved, or Cabbage Rose. 

 Orient, 1596. A beautiful, sweetly-scented species, grow- 

 ing to 6 feet in height, and having leaves that are 

 composed of from three to five broadly ovate, toothed 

 leaflets. The flowers are solitary, or two or three together, 

 drooping, and of a rosy hue, but differing in tint to a 

 considerable extent. This species has varied very much, 

 principally through the influences of culture and crossing, 

 the three principal and marked variations being size, 

 colour, and clothing of the calyx tube. There are the 

 common Provence Roses, the miniature Provence or 

 Pompon Roses, a^id the Moss Rose all of which are 

 merely races of R. centifolia. 



R. DAMASCENA. Damask Rose. Orient, 1573. A bushy 

 shrub varying from 2 feet to 8 feet in height according to 

 cultural treatment and age. The flowers are white or red, 

 large, borne in corymbose clusters, and produced in great 

 profusion during June and July. The varieties that have 

 arisen under cultivation by seminal variations, hybridi- 

 zation, or otherwise, are exceedingly numerous. Those 

 now grown are mostly double, and a large proportion of
