Leaves are simple or compound. Leaves are lobed or oval, and, they are broad oval or slim oval. To be a leaf the stem of the leaf must leave the main branch at a point where a bud occurs. In compound leaves there is no bud at the base of the leaflet. Compound leaves are further divided into palmately and pinnately compound.
Examples are ash, walnut, butternut, locust and hickory.
Simple leaves are those on a single stem having a bud at the base. Lobed Leaves Lobed leaves are divided into palmately and pinnately lobed. In the Palmately lobed, the lobes originate at the central point of the base of the leaf such as yellow poplar, the maples, gum and sycamore. In pinnately lobed they occur along the stem such as the oaks. Leaves Slim oval are those leaves which are more than twice as long as they are wide.
