 There seems to be no limit to the size of the plants

have constitut.d the mam part of the plants that 

 have been imported, while the B. miirimiim has until 

 lately been practically lost sight of, though the fact 

 remains that for many years B. maximum has con- 

 tributed to the establishment of a class of hardy 

 forms such as the variety Delicatissinium, in which 

 one finds the vigor of growth and size of foliage indica- 

 tive of the Maximum parentage, while the abundance of 

 bloom and color can be traced to that other parent, R. 

 Catawbiensp. Some other varieties are in commerce 

 that have had similar hardy parentage, and some seed- 

 lings are known in this country which combine great 

 merits but which up to the present time have not been 

 offered or propagated largely. Among these could be 

 mentioned the variety "James Comley," a seedling 

 originated by James Comley on the estate of Francis B. 

 Hayes, of Lexington, for which the Massachusetts 

 Horticultural .Society awarded a silver medal in 1898. 

 The great objection to the use of Hybrid Rhododendrons 

 has been their cost and the length of time that was
