Acacia occidentalis

This large Acasia grows primarily along xeroriparian washes subtropical Sonora and southern Sonoran Desert. Its appearance is very similar to Acacia greggii, but often grows much larger with finer foliage and branch tips, more leaflets per leaf, and a gland on the petiole which is usually between the base of the leaf and the first 2 pinnae, where as in greggii this gland is almost always between the first 2 pinnae.
