include all the monstrous variations in form and colour with 

 which nurserymen's catalogues are replete. The only criticism 

 the reviewer has of the arrangement of the book is that, in his 

 judgment, it would have been preferable that the full descriptions 

 of the species had preceded the varieties enumerated ; a casual 

 reader is apt to connect the ultimate paragraphs with the variety 

 last mentioned. 



In this connection it is a pity that most British nurserymen 

 enumerate alphabetically the varieties and species offered in 

 their catalogues indiscriminately ; for the result is that too many 

 buyers of conifers are unaware that they are buying a variety of 

 Lawson Cypress when they order " Cupressus erecta viridis,'' or 

 a juvenile form of Cryptomeria japofiica when they ask for 

 " Cryptomeria elegans.'" 



That Messrs Dallimore and Jackson's book should be in the 

 hands of all nurserymen who offer, and all amateurs who grow, 

 the Coniferae is quite certain. The writer has had his copy 

 bound in two volumes, and interleaved with lined paper for 

 notes, and he commends that plan to others. 



To foresters the book will prove of great value, as it deals 

 fully with all species which have become valuable for forestry 

 purposes or are likely to be so. The descriptions of the qualities 

 of the timbers of economic species are full and adequate, and 

 the book, therefore, may be confidently recommended to timber- 

 merchants. 



The misprints and errors are singularly infrequent. It may 

 be well, however, to point out that the date of introduction of 

 Gingko biloba to this country is 1754 and not 1795 as stated. 

 The latter year was when it first bore flowers at Kew. 



The authors speak of Pinus parviflora being found in the 

 Kurile Islands, this statement, doubtless, rests on the authority 

 of Siebold; but according to Wilson {Conifers and Taxads of 

 Japan) this is incorrect. F. R. S. Balfour.
