172 HARDY ORNAMENTAL 



R. BIFLORUS. Himalayas, 1818. A tall-growing species 

 with whitish, spiny stems, and simple three-lobed leaves 

 that are tomentose on the undersides. The flowers are 

 thickly produced, pure white, and render the plant highly 

 attractive and of great beauty. 



R. DELICIOSUS. This Rocky Mountain Bramble (1870) 

 is a very worthy species, with three or five-lobed (not 

 pinnate) leaves, and large pure-white flowers that are each 

 about 2 inches in diameter, and produced in profusion 

 from the leaf-axils. For ornamental planting this may 

 be placed in the first rank of the family to which it 

 belongs. 



R. FRUTICOSUS. Common Bramble, or Blackberry. Of 

 this well-known native species there are several worthy 

 varieties, of which the double-flowered are especially worth 

 notice, blooming as they do in the latter part of summer. 

 R. fruticosus flore albo-pleno (Double white-flowered 

 Bramble) and R. fruticosus flore roseo-pleno (Double red- 

 flowered Bramble) are very pretty and showy varieties, 

 and well worth including in any collection. There is a 

 pretty variegated-leaved form of the common Bramble, 

 known as R. fruticosus variegatus. 



R. LACINIATUS, Cut-leaved Bramble, might also be 

 included on account of its profusion of white flowers 

 and neatly divided foliage. 



R. LEUCODERMIS, from Oregon, is an interesting species, 

 with white flowers, and stems that appear as if white- 

 washed. 



R. NUTKANUS. North America, 1826. This has large 

 white flowers, but otherwise it resembles R. odoratus. 



R. ODORATUS. Purple flowering Raspberry. North 

 America, 1700. The sweet-scented Virginian Raspberry 

 forms a rather dense, upright-growing bush, fully 4 feet 

 high, with large broadly five-lobed and toothed leaves, that 

 are more or less viscid, sweet-scented, and deciduous. 

 The leaves are placed on long, hairy, viscid footstalks.
