Fruit: A round, fleshy, orange-red aril about 1/4 inch long containing one hard seed, exposed at the end. Twig: Round, slender, and remaining green for many years; relatively few lateral branches. Bark: Always thin (about 1/4 inch), reddish brown, and scaly; inner bark is reddish purple. Form: Small evergreen understory tree with indistinct growth form.
