FLOWEBING TREES AND SHRUBS 31 



C. DENTATUS. California, 1848. With deeply-toothed, 

 shining-green leaves, and deep-blue, abundantly-produced 

 flowers, this is a well-known wall plant that succeeds in 

 many parts of the country, particularly within the in- 

 fluence of the sea. It commences flowering in May, and 

 frequently continues until frost sets in. It is a very desir- 

 able species, that in favoured situations will grow to fully 

 10 feet high, and with a spread laterally of nearly the 

 same dimensions. 



C. PAPILLOSUS. California, 1848. This is a straggling 

 bush, with small, blunt leaves, and panicles of pale-blue 

 flowers on long footstalks. A native of California and 

 requiring wall protection. 



C. RIGIDUS, another Californian species (1848), is of 

 upright, stiff growth, a sub-evergreen, and with deep-purple 

 flowers produced in April and May. 



There are other less hardy kinds, including C. flori- 

 bundus, C. integerrimus, C. velutinus, and C. divaricatus. 



Cedrela (Meliaceae), 



CEDRELA SINENSIS (syn Ailanthus flavescens). China, 

 1875. This is a fast-growing tree, closely resembling the 

 Ailanthus, and evidently quite as hardy. It has a great 

 advantage over that tree, in that the flowers have an 

 agreeable odour, those of the Ailanthus being somewhat 

 sickly and unpleasant. The yellowish flowers are in- 

 dividually small, but arranged in immense hanging 

 bunches like those of Koelreuteria paniculata, and being 

 pleasantly scented are rendered still the more valuable. 

 The whole plant has a yellow hue, and the roots have a 

 peculiar reddish colour, and very unlike those of the 

 Ailanthus, which are white.
