Its petioles are 5–8 millimeters long. Its flowers are solitary or in pairs and axillary. Each flower is on a pedicel 2–5 millimeters long. Its flowers have 3 oval-shaped sepals that are 1.5–3 by 3–5 millimeters. The outer surface of the sepals is densely hairy. Its 6 petals are arranged in two rows of 3. The outer petals are pale green to yellow and 8–11 by 6–10 millimeters. The outer petals are densely hairy on their outer surface. The inner petals are similarly colored, 7–14 by 5–7 millimeters, and concave. The inner petals are smooth on their outer surface except for a hairy patch running from the tip to the base. It has numerous stamens that are 2–3.5 millimeters long. Each flower has 2–20 monocarps that are red, orange, purple or black at maturity and 9–14 millimeters wide.
