... 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
