HYBRID RHODODENDRONS.

recommend all who intend practising this very interesting branch 

 of horticulture, no matter what class of 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 con- 

 stitution of the plants and the result aimed at. We have in a 

 tabular form appended a description of eight distinct sections of 

 hybrid Rhododendrons, 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 diver- 

 sity in the characters of their foliage. We anticipate that many 

 of them will flower in the spring of 1852. and we shall derive 

 much pleasure in watching their different characters.

* When the name in this arrangement is printed in ordinary type, it 

 indicates the plant to have been a breeder: when in italics, "a hybrid 

 produced. Thus, Catawbiense, fertilized with pollen of Arboreum, produced 

 Altaclarense. Then taking Catawbiense as the female again, and fer- 

 tilizing it with the pollen of the hybrid Altaclarense, a race of excellent 

 flowers, such as Blandyanum. Towardii, &c, were produced.
