In 1832 the second edition of Lambert’s Genus Pinus appeared, 
wherein the Abietinee were all, as before, included under Pinus; which 
however was broken up by David Don (Lambert's Herbarium keeper)

n 1838 Loudon's great work, the Arboretum et Maik

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 is a 
clavis of the genera, where the genus Abies is attributed to Link, but 
the characters given to it are those of Link’s Picea; and in like manner
