PREFACE 



been employed where necessary, there is a detailed Glossary of over .'{50 

 Botanical terms with derivations of all words used, as well as lists of Latin 

 and Greek roots used in Floral nomenclature, and Latin, English, Natural 

 Order, and Colour Indices. 



The text is almost wholly the work of Mr. C. S. Cooper, Mr. W. Percival 

 Westell, in the capacity of General Editor, having collaborated and been 

 responsible for seeing the work through the press. 



The Authors wish to record their great indebtedness to Mr. George Paul, 

 .1.1'.. V.M.H., of Cheshnnt, and his staff, who have at all times placed their 

 valuable and unique experience at disposal and also enabled many points of a 

 difficult nature to be settled from direct observation of the living plants. They 

 are also under an obligation to Mr. II. R. Hutchinson, who, in his official 

 capacity of Librarian to the Royal Horticultural Society, has always treated 

 them with unfailing courtesy; and they desire to acknowledge the help accorded 

 in the preparation of the Useful Insects plate by Mr. A. E. Gibbs, F.L.S., 

 F.E.S. ; and by Mr. Claude Morley, F.E.S., who kindly supplied specimens of 

 Insects; also the valuable assistance accorded by Mr. Wm. Dallimore, of 

 the Royal Gardens, Kew, in the compilation of those parts of the Calendar 

 dealing with the Conifera?. 



The works of many of the greatest authorities have been rigidly and per- 

 sistently consulted, and the titles of some of the most useful of these are given 

 at the end of the second volume for the benefit of those who may desire 

 more extended information. 



The fine series of illustrations have all been specially drawn for this work 

 direct from Nature by Mr. C. F. Newall, and the Artist has spared no pains 

 to make his pictures thoroughly l-epresentative, and every detail technically 

 correct. He is himself an experienced Botanist and an Artist of no mean 

 calibre— a rare combination of great value in the accurate production of illus- 

 trative work of this kind.
