2. Trees with Ortunnviitnl Flowers. In making the 

 following grouping, arranged according to relative 

 hardiness, it has been impossible to give precise in- 

 formation as to the exact degree of frost-tolerance of 

 the several species, as we can rind but meager published 

 data on the subject.
