The hermaphrodite flowers are radially symmetrical with a double flower envelope . The white petals are egg-shaped with a length of 1.5 to 2.5 millimeters. 8 to 14 stamens stand together in a bundle .

The fruit is spherical or urn-shaped with a diameter of 4 to 5 millimeters and the opening is about 1 millimeter in size. The sepals remain on the fruit.
