Note. — It must be remembered that the typical leaves of a species are to 

 be found upon mature trees, not upon young ones. The leaf- 

 lets of a compound leaf can be distinguished from simple 

 leaves by the absence of leaf-buds from the base of their stems. 

 No guide has been prepared for the Conifers, as it is believed 

 the illustrations will be sufficient.
