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.
