It is a bush or small tree. Its leaves are 8.5-11 by 3-4.2 centimeters and rounded at their tips. The leaves are lightly hairy on their upper and lower surfaces. Its petioles are 3-4 millimeters long. Its solitary flowers are extra-axillary. Each flower is on a pedicel 1-1.6 centimeters long. Its flowers have 3 oblong sepals that are 4-5 millimeters long. The sepals are smooth, curved backwards, and have wavy or fringed margins. Its 6 petals are arranged in two rows of 3. The outer petals are yellow, 3.5-5 by 0.2-0.4 centimeters, and smooth or lightly hairy. The inner petals are similarly colored. The inner petals have a 0.3-0.7 centimeter long claw at their base and a 0.2-0.4 by 0.35-0.5 centimeter blade. The inner petals are smooth on their outer surface, and hairy inside.
