HYBRID RHODODENDRONS 35 
plants they propose to operate on, to choose the parents, 
whether species or hybrids, as far removed from each other 
as is consistent with the constitution of the plants and the 
result aimed at. We have in a tabular form appended a 
description of eight distinct sections of hybrid Rhodo- 
dendrons, and it will be seen that all our third crosses, 
although all hybrids, have been selected as distinct from 
each other as possible. The plants raised from these 
crosses are all as healthy as we could wish, and they present 
a very great diversity in the characters of their foliage.''
