7. Gandav6nsis, Hort. GHENT AZALEAS. Fig. 174. 

 These are hybrids between A . Pontica, and the American 



174. Ghent azalea A. Gandavensis (X 



species, and A. Sinensis, now more in cult, than the 

 typical species. Of a number of them the parents are 

 easily recognized, but many are hybrids of the second 

 degree or more, and it is impossible to be sure about 

 their parentage. They vary in all shades of white, yel- 

 low, orange, pink, carmine, lilac, and red, with single 

 and double fls., and also in the time of flowering, from 

 May to July. A short selection of some good varieties 

 has already been given.

dular.
