Taxonomic Information

Appearance

Arenga engleri is a small, slow-growing palm tree that typically reaches a height of 6-10 feet (1.8-3 meters) and a spread of 4-6 feet (1.2-1.8 meters). It has a single, slender trunk that is covered with persistent leaf bases. The leaves are pinnate, meaning they are divided into leaflets arranged on either side of a central axis. The leaflets are dark green, glossy, and lance-shaped, with pointed tips and saw-toothed edges. The plant produces small, cream-colored flowers that are arranged in clusters on branched stalks that emerge from the base of the leaves. The flowers are followed by small, round, black fruit that contain a single seed.
