The leaves are hairless on their upper and lower surfaces and except for the midrib which is densely hairy on the lower surface. The leaves have 18-24 pairs of secondary veins emanating from their midribs. Its hairy petioles are 3-6 by 1.5-2.5 millimeters with a groove on their upper side. Inflorescences are organized on short peduncles. Each inflorescence has up to 1-2 flowers. Each flower is on a densely hairy pedicel that are 7 by 0.5 millimeters. The flowers are unisexual. Its flowers have 3 triangular sepals, that are 1 by 1 millimeters. The sepals are hairless on their upper surface, hairy on their lower surface, and have fine hairs on their margins. Its 6 petals are arranged in two rows of 3. The circular, outer petals are 3.5 by 3.5 millimeters with hairless upper surfaces and densely hairy lower surfaces. The outer petals are purple. The diamond-shaped inner petals have a 0.6-1 millimeter long claw at their base and a 3.5 by 2.5-3 millimeter blade. The inner petals are pointed at their tip and base. The purple inner petals are smooth on their upper surface and densely hairy on their lower surface. Male flowers have up to 28 stamens that are 0.5-0.8 by 0.6 millimeters. Fruit are on densely hairy pedicels that are 10 by 2 millimeters. The fruit consists of up to 2 monocarps. Each mature monocarp is a 15-16 by 10-15 millimeter globe. The pale brown-green, mature monocarps are smooth and densely covered in hair. Each monocarp has around 5 seeds. The wrinkly, hemi-spherical seeds are 9-10 by 4.5-6.5 by 3-5 millimeters.[3]
