Trees can live to 250 years; young trees are fast growing, slowing down in maturity. It is usually found in riparian corridors within forest, woodland, chaparral, or grassland. The compound leaves are pinnate, 12-33 centimeter long, with 5-9 leaflets, and often show signs of disease and brown rot, even on otherwise healthy plants. The inconspicuous flowers are dioecious, meaning that male and female parts are contained in separate flowers. The fruit is a samara, and not usually produced until the tree reaches 20-30 years of age. Description from Calscape.org
