Fraxinus texensis (Texas ash, Texas white ash, or mountain ash[1]) is a species of Fraxinus, native to eastern Texas and southern Oklahoma. It is closely related to Fraxinus americana (white ash), and is sometimes treated as a variety of it, as Fraxinus americana var. texensis A.Gray.[2][3]

It is a small deciduous tree growing to 10 m tall, with a trunk up to 30 cm diameter. The leaves are 13–20 cm long, pinnately compound with usually five rounded leaflets 3–7.5 cm long and 2–5 cm broad. The flowers are purple, produced in small clusters in early spring; like all ashes, is dioecious, with male and female flowers on separate trees. The fruit is a samara 1.5-3 cm long, with an apical wing. It occurs on rocky limestone soils, and is drought tolerant.[3]
