Description

It is a tree reaching 10 meters in height. The young, light to dark brown branches are sparsely hairy and also have sparse lenticels. Its egg-shaped to elliptical, papery to slightly leathery leaves are 8.5-17 by 3-6.5 centimeters. The leaves have pointed bases and tapering tips, with the tapering portion 12-22 millimeters long. The leaves are hairless on their upper and lower surfaces. The leaves have 10-14 pairs of secondary veins emanating from their midribs. Its sparsely to densely hairy petioles are 4-10 by 1-2 millimeters with a broad groove on their upper side. Its Inflorescences occur in pairs on branches, and are organized on slightly to sparsely hairy peduncles that are 1.5-3 millimeters. Each inflorescence has up to 18 flowers. Each flower is on a slightly to sparsely hairy pedicel that is 3-9 by 0.2-0.5 millimeters. The pedicels are organized on a rachis up to 5 millimeters long that have 3-18 bracts. The pedicels have a medial, densely hairy bract that is 0.5-1 millimeters long. Its flowers are unisexual. Its flowers have 3 free, triangular sepals, that are 0.7-1 by 1-1.5 millimeters. The sepals are hairless on their upper surface, sparsely to densely hairy on their lower surface, and hairy at their margins. Its 6 petals are arranged in two rows of 3. The pale yellow to pink, oval, outer petals are 1.5-2 by 1-2 millimeters with hairless upper and sparsely hairy lower surfaces. The pale yellow to pink, triangular, inner petals have a 1-2 millimeter long claw at their base and a 2-3.5 by 1.5-2.5 millimeter blade. The inner petals have flat bases and pointed tips. The inner petals are slightly hairy on their upper and lower surfaces. The inner petals have a single, smooth, flat, sausage-shaped gland on their upper surface. Male flowers have up to 26 stamens that are 0.6 by 0.5-0.6 millimeters. Female flowers have up to 5 carpels that are 1 by 0.5 millimeters. Each carpel has 2 ovules. The fruit occur in pairs and are organized on a sparsely hairy peduncle that is 3 by 1 millimeters. The fruit are attached by sparsely hairy pedicles that are 15 by 1 millimeters. The globe-shaped fruit are 7-9 by 7-9 millimeters. The fruit are wrinkly, and densely hairy. [4]

Reproductive biology

The pollen of P. parvipetala is shed as permanent tetrads. [6]

Habitat and distribution

It has been observed growing in sandstone or clay soils in lowland forests or rocky outcrops at elevations of 100-230 meters. [4]
