| Birchleaf Buckthorn|
Frangula betulifolia (Rhamnus betulifolia)
In Texas birchleaf buckthorn may be found infrequently in the moist canyons and upper slopes from 4000 to 7000 feet in the Trans-Pecos. It also occurs in Mexico, New Mexico, Arizona, Utah and Nevada. This large shrub or small tree is often branched near the base, growing with an upright, rounded form. Its 2-inch to 6-inch-long by 1 1/2 inch wide leaves are bright shiny green above, paler and somewhat hairy beneath. They are browsed by mule deer. The black fruit, which mature from July through October, are a food source for a variety of birds.
