About Fraxinus dipetala Hook. & Arn.
Fraxinus dipetala, commonly known as California ash or two-petal ash, is a species of ash. It is native to southwestern North America: in the United States it grows in northwestern Arizona, California, southern Nevada, and Utah, and in Mexico it is found in northern Baja California. This species grows at altitudes between 100 and 1,300 meters. It is a deciduous shrub or small tree that reaches up to 7 meters in height, with stems that range from cylindric to four-angled in shape. Its leaves are 5 to 19 centimeters long, and range in color from light to dark green. Each leaf holds three to seven, rarely nine, leaflets that are 1 to 7 centimeters long, thick in texture, and have serrated margins. Its flowers have two white lobe-shaped petals 2.5 to 4 millimeters long, are sweetly scented, and hang in fluffy clusters. Unlike many ash species, its flowers are bisexual rather than dioecious. The fruit of Fraxinus dipetala is a long, flat samara that is 2 to 3.2 centimeters long and 5 to 9 millimeters wide. It is green when immature, and grows hanging in bunches.
