Leaves of the Oregon ash
Description
Fraxinus latifolia can grow to 25 metres (82 ft) meters in height, with a trunk diameter of 30-80cm. The compound leaves are pinnate, 12-33 cm long, with 5-9 leaflets, each leaflet ovate, 6-12 cm long and 3-4 cm broad, and often show signs of disease and brown rot, even on otherwise healthy plants. The fruit is a samara, 3-5 cm long including the wing.[1][2]
The Oregon ash prefers damp, loose soils, and grows from sea level to 900 metres (3,000 ft) in elevation, up to 1,700 metres (5,600 ft) in the south of the range in California. In central Southern California, it intergrades with Fraxinus velutina (Velvet ash) of southern California east into Arizona.[1][2]
