ADDENDA. 



Henry G. Bohn has thought it desirable, in the present re-issue of 

 Gordon's Pinetum, to add a list, of references to the coloured plates 

 given in the three great, and now scarce and expensive, English 

 works devoted to the illustration of Coniferse ; and this idea has 

 met with the approval of his botanical friends. The following are 

 the names of the books referred to : 



Lawsons' Pinetum Britannicum, published by subscription in 

 37 parts, atlas folio, 1866-73, contains 4-1 coloured plates besides 

 numerous engravings, but as none of these are numbered, it 

 has been found necessary, by way of facilitating reference, to 

 adopt numbers according to the order of the letterpress. 

 Lambert's Genus Pinus, edited by Professor Don, 3 vols., 

 atlas folio, second and most complete edition, 1837, with 101 

 coloured plates and two very large uncoloured ones. These 

 plates being only numbered up to 51, the subsequent ones are 

 numbered in the order of the letter-press. 

 The Pinetum Worurnense, a catalogue of the Coniferous 

 Plants in the collection of the Duke of Bedford at Woburn 

 Abbey, systematically arranged by J. Forbes, imperial 8vo., 

 1839, containing 68 coloured plates. 



There are many foreign works which incidentally contain coloured 

 illustrations of local Coniferre, such as those of Jacquin, Pallas, Hum- 

 boldt, Sibthorp's Flora Grseca, etc., etc., but one of the most accessible 

 and comprehensive in this department is Michaux's North American 

 Sylva, with Nuttall's continuation, together 6 vols., royal 8vo., Phila- 

 delphia, 1840-49, containing 278 coloured plates. 



* ie * All the above-named works, in case of need, are to be found in the 

 fine library of the Linncean Society, and of course in the British Museum.
