Many cultivated plants from public parks and private gardens 
have been added to the list, because such plants are frequently 
brought into the class-rooms of our schools as material for 
study. All the species enumerated, not considered to be 
natives of the region, have their respective native countries 
indicated. 
The following sources have been consulted in compiling 
the catalogue, viz.:
