Wild coffee (Psychotria nervosa) has interesting leaves that are about 6 inches long. The leaf veins are distinctly impressed on the upper leaf surface and you can find fine hairs on the underside of the leaves along the main mid-rib. The leaves and fruits are somewhat similar to the invasive coral ardisia (Ardisia crenata), but wild coffee grows larger and is less cold tolerant. Additionally, the leaves are opposite with entire margins, as opposed to coral ardisia's leaves which are alternate with scalloped margins.
