In 1803 was published the first edition of Lambert’s 
Genus Pinus, containing about 35 species of Abietinece, 
all included under Pinus. 
In 1813 the second edition or the Hortus Kewensis 
appeared, in which, as before, all the Abietinece, 
(inci'eased to 29) are included under Pinus. 
In 1826 Louis Claude Richard’s Memoire sur les 
Coniferes was edited by his son. This classical work is 
the earliest that dealt scientifically with the order 
Coniferce, and in it the Tribe Abietinece was first esta- 
blished, to include Pinus (under which were placed 
Spruces and Silver Firs), and Larix (which included the 
cedars), to these were added, Cunninghamia, Ago, this 
(Dammam), and Araucaria, which now form a distinct 
Tribe. 
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 
Ceclrus. 
In 1832 the second edition of Lambert’s Genus Pinus 
appeared, wherein the Abietinece were all, as before, 
included under Pinus ; which however was broken up by 
David Don (Lambert’s Herbarium keeper) into six 
sections, Pinus, Strobus, Abies (for the Spruces), Picea 
(for the Silver Firs and Tsugas), Larix, and Cedrus. 
About 48 species in all are described. 
In 1838 Loudon’s great work, the Arboretum et Fruti- 
cetum Britannicum appeared. The Tribe Abietinece 
is here adopted as defined by Richard, with the genera 
Pinus, Abies, Picea, Larix, and Cedrus: and here that 
confusion of Abies and Picea which so distresses British 
foresters and planters had its origin. At p. 2105 there
