The document summarizes information about the Fraxinus angustifolia, or common ash tree. It is a medium-sized deciduous tree that can reach 25 meters tall, with light green spear-shaped leaves. It bears small seeds called samaras that are dispersed by wind. The tree grows in wet soils near water sources in southern and eastern Europe, below 1500 meters where frost is less common. Its wood is useful for furniture, tools, and preventing erosion, while cattle consume its leaves and roots which are believed to prevent sickness.
