Cyclopedia of American horticulture, comprising suggestions for cultivation of horticultural plants, descriptions of the species of fruits, vegetables, flowers, and ornamental plants sold in the United States and Canada, together with geographical and biographical sketches. Gardening. 141: POPULUS grown here thau the varieties with lobed and very white- bottomed (and sometimes variegated) leaves. Var. nivea, Wesm. (/*, iiirea, Willd. P. arqentea, Hort.). This is the commonest form of white Poplar in this country. It is known by the snow-white under sur- faces of its foliage and the :i- or 5-lobed maple-like leaves. It is far too frequent about old yards, where its inveterate brood of suckers make it a perpetual nui- sance. It is sometimes called Silver Maple, from the resemblance of its foliage to that of the maple. As a street tree in cities it is particularly offensive, for the cottony covering of the under side of the leaves and of the shoots holds soot and dust, and it looks repulsively dirty. Useful for foliage effects in large but not lobed, the under surfaces and the young shoots very gray-woolly. This tree is met with occasionally. Its horticultural value is not greatly different from that of var. nin-a. By some thought to be a hybrid of P. alba and P. Tremula. ,Lauch. (). Bolles'Poplar. Fig. 1919. A very tall, narrow-topped tree, with cottony Ivs. rather more deeply lobed than those of the var. nivea. The tree was introduced into Europe in 1875 from Turkestan, and it was named for Dr. C. Bolle, an arboriculturist. It bears about the same relation to Populus alba that the Lomhardy Poplar bears to Popii- lits ni(ira. Its fastigiate habit, combined with the white foliage and shoots, makes it a most emphatic tree, and there is great danger of planting it too freely. Seems to be short-lived. L. jj. B.
