ユーカリ、ジャラ（Eucalyptus marginata）

Name	Description
説明	Eucalyptus marginata, commonly known as jarrah, is a species of eucalypt tree belonging to the Myrtaceae family and native to the southwestern region of Western Australia, where it grows in coastal areas and can reach impressive heights of 30 to 40 meters with trunk diameters ranging from 1 to 1.5 meters, characterized by its dark red to purplish heartwood which tends to develop darker hues over time and features striking irregular streaks due to the presence of gum veins; with a specific gravity of 0.82, the wood is heavy and hard, yet highly durable, making it suitable for a variety of applications including construction uses such as wharves, bridges, and piers, as well as decorative applications such as furniture due to its attractive aesthetic, although the wood's processing presents challenges as it is prone to warping and splitting during drying, and while it responds well to adhesives, it proves difficult to nail; with a straight, interlocked, or wavy grain pattern and a somewhat coarse texture, its durability is especially valued in situations requiring resistance to wear and the elements, which has led to its historical use for railroad sleepers and more modern uses in veneer, cabinetry, maritime construction, and other areas where its visual appeal and robustness can be exploited.
