Linnaeus, in 1753, included these all under Pinna, of 

 "which he enumerated 10 species. 



In 1789 A. L. de Jussieu, in his Genera Plantarum, 

 has only two genera, Pinus and Abies. 



In the same year the first edition of Aiton's Hortus 

 Kewensis appeared, wherein all the Abietineae (19 species) 

 are included under Pinus. 



In 1803 was published the first edition of Lambert's 

 Genus Pinus, containing about 35 species of Abietineae, 

 all included under Pinus. 



In 1813 the second edition of the Hortus Kewensis 

 appeared, in which, as before, all the Abietineae 

 (increased to 29) are included under Pinus. 



In 1826 Louis Claude Richard's Memoire stir les 

 Goniferes was edited by his son. This classical work is 

 the earliest that dealt scientifically with the order 

 Coniferae, and in it the Tribe Abietineae was first 

 established, to include Pinus (under which were placed 

 Spruces and Silver Firs), and Larix (which included the 

 Cedars) ; to these were added, Gunningliamia, Agathis 

 ■(Dammar a), and Araucaria, which now form a distinct

In 1827 Link, in the Journal of the Academy of 

 Sciences of Berlin, proposed the five genera : Pinus, 

 Picea (for Spruces), Abies (for Silver Firs), Larix, and 

 Gedrus. 



In 1832 the second edition of Lambert's Genus Pinus 

 appeared, wherein the Abietineae were all, as before, 

 included under Pinus ; which however was broken up 

 by David Don (Lambert's Herbarium keeper) into six
