60 HARDY ORNAMENTAL 



D. CANESCENS. Japan, 1837. This has slender branches, 

 with ovate-lanceolate, roughish leaves, and terminal panicles 

 of whitish flowers. There is a double-flowered variety. 



D. CORYMBIFLORA. A charming species with finely- 

 toothed, ovate-lanceolate leaves and a rich abundance of 

 white flowers. It grows freely and is a valuable addition 

 to our flowering shrubs. 



D. CORYMBOSA, from the Himalayas, has elliptic-lance- 

 olate leaves and white flowers. It grows about 5 feet high. 



D. CRENATA (syn D. scabra and D. Fortunei). Japan, 

 1863. This is of stout, bushy growth, often reach- 

 ing a height of 8 feet, and lateral spread of nearly as 

 much. The ovate-lanceolate leaves are rough to the touch, 

 and its slender but wiry stems are wreathed for a con- 

 siderable distance along with racemes of pure-white flowers. 

 It is a very distinct shrub, of noble port, and when in 

 full flower is certainly one of the most ornamental of 

 hardy shrubs. The double-flowered form, D. crenata 

 flore-pleno, is one of the prettiest flowering shrubs in 

 cultivation, the wealth of double flowers, not white as in 

 the species, but tinged with reddish-purple, being highly 

 attractive. D. crenata, Pride of Rochester, is another 

 form with double-white flowers, and a most distinct and 

 beautiful shrub. Two other very beautiful varieties are 

 those known as D. crenata Watererii and D. crenata 

 Wellsii. 



D. DISCOLOR CARNEA and D. DISCOLOR LACTEA are the 

 results of crossing D. scabra and D. discolor, the former 

 having widely expanded and reflexed flowers which are of 

 a blush colour, with the reverse of the petals of a deeper 

 hue. 



D. DISCOLOR PURPURASCENS (Yunnan, 1894) grows about 

 a yard high and bears an abundance of flowers, which 

 are tinted with rosy purple. 



D. GRACILIS is a somewhat tender shrub of fully 18 

 inches high, with smooth leaves and pure-white flowers
