HYBRIDISATION IN THE UNITED STATES. a3 
development of ornamental plants, as we have in the development of 
fruits. Nearly 3,000 native species are now in cultivation as ornamental 
subjects. Already there is amalgamation of types, but it is evident that 
the process has only begun. It is possible that we may be able some 
day to offer the European gardener something of interest. 
The greatest work of the hybridist is the development of tendencies 
and races rather than varieties. The slow and repeated amalgamation 
or blending of types is the consummation of plant-breeding. The pro- 
duction of a single hybrid which may be named and sold brings more 
present glory, but it is only an isolated fact. The best results come 
when species have been so completely blended that we cannot say which 
are hybrids and which are not.
