FOREWORD 



IN this little book I have endeavored to set 

 forth an informal sketch of three flower fami- 

 lies growing in the United States, east of the 

 Rocky Mountains, and in Canada, together 

 with a few stray relatives from the Pacific 

 slope, illustrated by faithful color studies of 

 the more prominent examples.
