Populus Canescens, Or The Populus Alba,Ian-Naeus, the common white or gray poplar, with its many forms or varieties of Abeles, Athenian, maple-leaved and silver poplar.
Though widely diffused and planted everywhere, and multiplied wonderfully by numerous suckers in their new home, these are believed to be of European origin. If correctly understood, my good friend, Professor Karl Koch, of Berlin, who has made a life study of trees, considers this species to be American, or common to both hemispheres. His valuable work† is unfortunately not at hand.
Populus tremula, Linn, is a small tree in Europe which may some day be united with our P. tremuloideus. It is chiefly valued as a first crop on devastated tracts to prepare the soil for that of greater utility, says Simone.†
In Southern Europe the white poplar becomes a noble tree, and the timber is much used in the construction of dwellings. It may be found valuable by our Western planters. Michaux claims two distinct trees, the white and the gray, attributing superiority to the latter.
