FROM the time of Kaempfer and that of Thunberg to our own day, the Japanese Conifers have been the objects of special predilection on the part of botanists. Zuccarini figured and described several that had been collected by Siebold, Lindley, Andrew Murray, Maximowicz, Franchet, and others, contributed greatly to the elucidation and delimitation of the several species. Robert Fortune, John Gould Veitch, and Charles Manes introduced many to our gardens. Horticulture has, indeed, rendered great service in this matter. The trees in question are valuable for ornamental purposes, and potentially as timber trees. The consequence of this is that collectors have accumulated specimens in large numbers and in different stages of growth. They have, moreover, supplied our nurserymen with seed, so that young plants are now numerous in our nurseries and plantations. Monographie der Abietineen des Japanischen Reiches.
