PREFACE. 



THIS Hand-list might properly have formed part 

 of that of the "Trees and Shrubs grown in the 

 Arboretum," but so many persons possess collections of 

 Conifers who are not interested in other ligneous plants 

 that there was an obvious convenience in treating them 

 separately. There was the further advantage that this 

 enabled the species which are grown under glass to be 

 included. The natural order, or rather group, Goniferae y 

 is so well defined that it is desirable to enumerate in one 

 list all the species actually in cultivation at Kew. 



The present Hand-list (first edition) comprises 227 

 species, with 340 varieties, belonging to 37 genera. 



Sir Joseph Hooker, the late Director of the Royal 

 Gardens, had contemplated the preparation of a Catalogue 

 •of the Kew Pinetum. In view of this he had drawn up 

 a brief review of the literature of the subject, which he 

 has now, after revision, kindly permitted to be used. 



" In the following list the species are referred to the 

 genera under which they have been placed by the latest 

 authorities, who have revised the Order Coniferae. That 

 such an authoritative list should be published is the wish.
