Speckled Alder

A small- to medium-sized tree 15–20 metres (49–66 ft) tall with smooth grey bark even in old age, its life span being a maximum of 60 to 100 years. The flowers are catkins, appearing early in spring before the leaves emerge.  The seeds are small, 1–2 millimetres (1⁄32–3⁄32 in) long, and light brown with a narrow encircling wing.
