Excerpt: ... THE ABELE. Po'puliu al'ba L. The two genera Populus, the Poplars, and Sal'ix, the Willows, constitute the Natural Order Salic'acece, a group of catkin-bearing trees and shrubs not very obviously allied to any others. Though varying greatly in dimensions, all of thern are perennial woody plants, generally of rapid growth, and producing a soft white wood. Their leaves are deciduous and undivided, spring singly from the nodes, and are furnished with stipules; and their flowers are in conspicuous catkins, the two sexes being on different plants (" dioecious "). This introduces a double difficulty into the study of the group, for not only do the staminate and carpellate trees of one species sometimes differ to some extent from one another, but hybrids or cross-bred trees frequently occur in a natural state, and still more frequently where, as in withy-eyots, several kinds are cultivated side by side. The flowers are of a very much simplified type, the "perianth"--the calyx and corolla, that is, of an ordinary flower--being replaced by simple minute scales. These scales being single--i.e. there being but one to each flower in the catkin -- they are probably really rather of the nature of bracts; whilst the perianth may be looked upon as altogether absent in Willows, though perhaps represented by a little one-sided, cup-shaped body, called a "disk," in the Poplars. This little cup occurs in both staminate and carpellate flowers, springing from the axil of the bract or scale and surrounding either the stamens or the oyary, as the case may be. In both genera the female flower consists of a one-chambered ovary surmounted by a more or less two-lobed stigma, and forming a small capsular fruit, which splits open by the rolling backward and downward from its apex of two valve...
