This is called opposite branching.#N#You can easily use this to differentiate from other trees like hickory, oak and cottonwood that have alternate branching, meaning the leaflets are growing from different, alternating points of the stem. 3 The leaves themselves are characteristic as they’re compound leaves, often growing 5 to 9 leaflets per leaf, as shown in the slideshow below.
