56 THE EHODODENDEON. 



Rhododendron califoenicum. 



This species is a native of California, and is well 

 worthy of cultivation wherever it proves hardy. 

 The chances are, it will not stand the wiaters in 

 New England. In England it is hardy, a writer

 well." 



The flowers are rosy, very showy ; and the habit 

 of the plant is good. Fig-ured in Bot. Mag. 81, 

 t. 4863.

A nohle species, native of Nepal, attaining larger 

 size than any of the family, the trunks being found 

 twenty feet high and twenty-four inches in diameter. 

 The foliage is large, dark green above, silvery be- 

 neath ; the flowers bright scarlet, in dense heads. 



This species varies much in the color of the 

 flowers : in the wild state they are found of every 

 shade, from deep scarlet to pure white ; and in culti- 

 vation numerous varieties have been raised, differing 

 greatly in color, markings, and size of flowers, and 

 in foliage. 



Some of these are among the most valuable Rho- 

 dodendrons for greenhouse culture and for forcing. 

 With us all are tender, and require greenhouse 

 protection. As they bloom very early in the spring, 

 they are not suitable for outdoor culture, even if 

 protected by removal to the cellar in winter. For
