ARBORETUM AND FRUTICETUM. 



PART III. 



four in a corymb, white. Sepals ovate, longly acumi- 4(54 



nate, glabrous, as long as the petals. Allied to R. 

 odoratus, but the peduncle and calyx are glabrous. 

 (Dec. Prod., ii. p. 566.) A native of the north-west 

 coast of North America, from New California to 

 NTootka Sound, and at various places between north 

 latitude 43° and 52°, in mountains and woods. It 

 was discovered by the unfortunate Douglas, and intro- 

 duced into Britain in 1826. It grows, in good soil, to 

 the height of 5 ft. or 6 ft., and has the general aspect 

 and appearance of R. odoratus, except being of a 

 paler green. It flowers from May to October, and 

 the flowers are white. These are succeeded by large 

 red berries, which are found to make excellent tarts ; and the plant will 

 probably soon be ranked as a fruit shrub. There are fine plants of this 

 species in the Horticultural Society's Garden, and at High Clere ; and they 

 may be purchased in the London nurseries at from Is. 6d. to 2s. each. 



App. i. Species and Varieties of Rubus best deserving of Cut- 

 tivation in British Gardens, as ornamental Shrubs.

 varieties recommended are, the double-flowered, the double pink-flowered (if it can be got), the 

 variegated-leaved, and R. f. tauricus, on account of its large and excellent fruit. 



R. corylifolius, the Hazel-leaved Bramble, No. 15. ; and fig. 457. in p. 741. 



C. Prostrate Brambles. 



R. cc^sius, the grey Bramble, or Dewberry, No. 11. ; and fig. 454. in p. 739. The variety recom-

Remark. The plants in the last two groups are propagated by division of the roots, or by en- 

 couraging the points of the shoots to root, like the runners of a strawberry; and the plants in the 

 first group by division of the root, or by suckers. All the kinds may be propagated by layers or 

 cuttings of the current year's wood, with the leaves on in a growing state ; and the cuttings in sand 

 under a glass, but not readily.
