PREFACE 
or in the Glossary at the end. The object has rather been to supply 
a few interesting notes descriptive of the plants delineated and their 
allies, with such reference as space permits to their geographical 
distribution, physiology, cultivation, folk-lore, and uses. 
We wish to thank the many friends who have helped us, by sending 
specimens of some of the less common species, and by advice and 
criticism ; and the managers and craftsmen of the Menpes Printing and 
Engraving Company, for the great pains they have taken in the 
production of our work.
