PREFACE WILD FLOWERS 



Wilhelm Miller, Leonard Barren, 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.
