Bocagea latifolia Blume | |
Pseuduvaria latifolia is a species of plant in the family Annonaceae.[1] It is native to Java.[2] Carl Ludwig Blume, the German botanists who first formally described the species using the synonym Bocagea latifolia, named it after its broad (latus in Latin) leaves (folium in Latin).[3][4]
Description
It is a tree reaching 10 meters in height. The young, dark brown to black branches are sparsely covered in lenticels. Its elliptical to oval, papery to slightly leathery leaves are 9.5-19 by 4-7 centimeters. The leaves have slightly heart-shaped bases and tapering tips, with the tapering portion 3-20 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 hairless petioles are 2-5 by 0.8-3 millimeters with a broad groove on their upper side. Its Inflorescences occur in clusters of 1-5 on branches, and are organized on slightly hairy peduncles that are 1.5-4 by 0.3-0.7 millimeters. Each inflorescence has up to 2 flowers. Each flower is on a slightly hairy pedicel that is 11-24 by 0.2-0.8 millimeters. The pedicels are organized on a rachis up to 5 millimeters long that have 2-6 bracts. The pedicels have a medial, slightly hairy bract that is 0.5-1 millimeters long. Its flowers are unisexual. Its flowers have 3 free, triangular sepals, that are 1.5-2 by 1.5-2 millimeters. The sepals are hairless on their upper surface, sparsely hairy on their lower surface, and hairy at their margins. Its 6 petals are arranged in two rows of 3. The pale yellow, oval, outer petals are 3-5 by 3-5.5 millimeters with hairless upper and sparsely hairy lower surfaces. The pale yellow, diamond-shaped inner petals have a 2-3.5 millimeter long claw at their base and a 5-9.5 by 2-5 millimeter blade. The inner petals have pointed bases and tips. The inner petals are hairless on their upper surfaces and densely hairy on their lower surfaces. The inner petals have a pair of elliptical, smooth, raised glands on their upper surface. Male flowers have up to 40-58 stamens that are 0.7-0.8 by 0.7-0.8 millimeters. Female flowers have 3-6 carpels that are 2.2-2.7 by 0.8-1.3 millimeters. Each carpel has up to 6 ovules arranged in two rows. The fruit occur in clusters of 3 arranged on slightly hairy peduncles that are 3-4 by 1-2 millimeters. The individual fruit are attached by slightly hairy pedicles that are 24-26 by 1.5 millimeters. The fruit are oval to elliptical and 18-21 by 12-14 millimeters. The fruit have a pointed tip 1 millimeter long. The fruit are smooth, and densely hairy.[5]
Reproductive biology
The pollen of P. latifolia is shed as permanent tetrads.[6]
Habitat and distribution
It has been observed growing in forests at elevations of 150 meters.[5]
