4 PREFACE 



all time. Newly introduced plants belonging to new 

 genera should have distinctive names for our country, 

 but the old names used in their native country would 

 be generally best for our use. 



The largest, latest, and best work on ornamental plants 

 in America is Bailey's " Cyclopedia of Horticulture," and 

 the names there given are in almost all cases the ones 

 here used. Where changes occur to suit popular usage

Many of us are afraid of anything looking like a key. 

 Keys in manuals have gradually been rendered more and 

 more difficult by the introduction of a larger and larger 

 number of scientific words applying in many cases to 

 microscopic features ; intelligent ones among us with an
