⁂ A fine set of this comprehensive work on conifers, by the grandson of William Robert Baker who planted a pinetum at his estate near Hertford advised by John Claudius Loudon. It was further developed by the author in the early 20th century and now belongs to the University of Hertfordshire, containing over 150 different species of conifer.

Frederick Robert Stephen Balfour (1873-1945) contributed the chapter on botany; his own collection of trees and shrubs at Dawyck, in Scotland, was described by H.J.Elwes as "a place of pilgrimage to all lovers of arboriculture".
