. Our native trees and how to identify them; a popular study of their habits and their peculiarities. Trees. WILLOW FAMILY the summer. On some species, however, they are small, in- conspicuous, and fugacious. The character of the inflorescence is the same in every species. It is dioecious, that is, the stamens and pistils are separate and borne on different trees. This makes the fam- ily difficult to classify, for it is necessary to study two trees in order to determine one species, and the two trees are not always at hand. Furthermore, the species readily hybridize, and also quickly respond to environment, so that only an ex- pert is competent to decide a question with regard to species among willows. The staminate flowers are without either calyx or corolla ; they consist simply of stamens, in number varying from two to ten, accompanied by a nectariferous gland and inserted on the base of a scale which is itself borne on the rachis of a drooping raceme called a catkin, or anient. This scale is oval and entire and very hairy. The anthers are rose colored in the bud but orange or purple after the flower opens, they are two-celled and the cells open longitudinally. The filaments are thread- like, usually pale yellow, often hairy. The pistillate flowers are also without calyx or corolla ; and consist of a single ovary accompanied by a small flat gland and inserted on the base of a scale which is likewise borne on the rachis of a catkin. This ovary is one-celled, the style two-lobed, and the ovules numerous. The fruit is a one-celled, two-valved, cylindrical, beaked capsule, contain- ing many minute seeds which are furnished with long, silky. white hairs. The catkins appear before or with the leaves. Although catkin and anient are interchangeable words, cat- kin seems most appropriate for the flowers of the willow be- cause of their furry appearance when half developed. The genus Salix is admirably fitted to go forth and in- habit the earth, for it is tolerant of all s
