WILD FLOWERS PREFACE 
Specimens may be pressed in books or between blotters, 
and mounted on cards when dry, with thin strips of 
couyt-plaster, and neatly labeled with date, and locality. 
The scientific names and classification in the text 
follow the method adopted by the International 
Botanical Congress at Vienna, June, 1905, and now 
incorporated in the new seventh edition of “ Gray’s 
Manual,” most extensively used as the class text-book 
in the public schools, thus appealing strongly to 
both teacher and student by its uniform system of 
nomenclature. Two Indexes are provided — one for 
the Common names and one for the Latin, which 
have been separated to avoid confusion and to 
facilitate ready reference. Technical terms have 
been simplified or disregarded wherever possible, and 
the few which have been retained are defined in the 
Glossary at the end of the text. In order to assist 
in the pronunciation of the Latin names the vowels 
have been accented. The grave or long (‘) accent 
signifies the long vowels; the acute or short (’), short 
vowels. Naturally, many references have been made 
to various works on this comprehensive subject. 
“ Gray’s Manual,” and Britton and Brown’s “ Tllus- 
trated Flora’? have been freely consulted. The 
colours, descriptions, common names and ranges 
are usually in strict accordance with these authorities, 
to which I especially desire to extend full acknowl- 
edgment. I am also very grateful for the unlimited 
and professional advice extended by Herman Merkle, 
Chief Forester of the New York Zodlogical Park,
