ORNAMENTAL PALMS 255 



ous flowers of a greenish white color, but having 

 long, feathery seed coverings that give them 

 interest, and being in addition strong growers. 



These have already been named among the 

 species of clematis that were used in hybridizing 

 experiments. 



It was to be expected that plants having 

 strains of such hardy species in their heredity 

 would develop some varieties of great hardiness. 

 And in this the expectations were not disap- 

 pointed. A more extended series of experiments 

 than I had planned to undertake would be neces- 

 sary to fix the new varieties, and to make sure 

 as to which of them are the hardiest. 



There is still opportunity for fine work iu this 

 direction. The clematis is such a beautiful vine, 

 and there are so many species available, and 

 among these species such amazing variety of 

 form of vine and flower, that the opportunity for 

 extensive breeding experiments with this type is 

 most inviting. 



In raising the seedlings my practice was to 

 sow the seed quite thickly in boxes in the green- 

 house, as soon as it ripened in the fall, forcing 

 the plants throughout the winter, and transplant- 

 ing them in the open field in the early spring. 

 The seedlings would quite often make vines from 

 eighteen inches to two feet long the first season,
