PREFACE. 



In producing a Supplement to the Pinetum at the 

 present time, it is only necessary to refer to the frequent 

 introduction of new Conifers, or what are said to be new 

 ones, together with the mutability of names, and the 

 Babylonian confusion which still exists in their nomencla- 

 ture, from the misapplication of names, either through 

 ignorance or design. The trade lists, too, with some 

 praisew^orthy exceptions, still abound with numerous 

 aliases, as may be seen by a slight comparison of such 

 lists with the ample indexes given at the end of the 

 Pinetum, and the present Supplement, where all the 

 synonymes are printed in Italics. 



Amongst the additional species and varieties recorded 

 in the present Supplement, will be found several which 

 have not before been enumerated, together with other in- 

 formation of a recent date, particularly the identification 

 and correction of M. Koezl's Mexican Pines ; and the noti- 

 fication of some errors of long standing in books of autho- 

 rity ; the whole being completed with an Index, containing 

 all the systematic names to be found in the present Supple-
