Goniothalamus uvarioides is a species of plant in the family Annonaceae. It is native to Peninsular Malaysia and Thailand.[2] George King, the British botanist who first formally described the species, named it after its fruit which he thought resembled those of the genus Uvaria more than those of Goniothalamus.[3]
It is a bush reaching 1.8 to 4.6 meters in height. Its petioles are 1-3.5 centimeters long and have a channel. Its oblong to oval, somewhat leathery leaves are 32-48 centimeters long with minute wedge-shaped bases. Its leaves have 22-35 pairs of secondary veins emanating from their midribs that arch to meet one another at the leaf margins. Its flowers are on pedicels that are 1-1.6 centimeters long. Its leathery, rounded sepals are 1.2-1.6 centimeters long and covered in fine hairs. Its flowers have 6 petals in two rows of three. The very leathery, yellow, broad, lance-shaped outer petals are 3.8 centimeters long with thickened bases. The very leathery, yellow, broad, lance-shaped inner petals are 2.5-3 centimeters long with contracted at bases. Its flower have stamen with connective tissue between the lobes of the anthers that extend upward to form a conical apex. Its flowers have carpels with hairy ovaries, cylindrical styles and small stigma with a cleft. Its oblong, hairy fruit are 3.1-4.4 by 1.5-1.8 centimeters with tapering tips and bases. The fruit have 4-5 wrinkled seeds that are 1.3 centimeters long. The fruit are attached to their pedicel by stipes that are 1.1-1.8 by 0.3 centimeters.[3][4][5]
The pollen of G. uvarioides is shed as permanent tetrads.[5]
It has been observed growing in lowland forests at elevations of 100 to 450 meters.[4]
