PREFACE WILD FLOWERS 
Wilhelm Miller, Leonard Barron, and the many other 
personal friends who have assisted me. 
To my dear mother, who has always encouraged 
me in my Nature studies; to my loving wife, for her 
help, at home and afield, with notes and specimens; 
and to my bonny boy, whose many inquiries have 
suggested this undertaking, I owe my everlasting 
gratitude and affection.
