The flowers are borne singly on the ends of the branchlets on a pedicel 1–3 mm (0.039–0.118 in) long. There are five broadly triangular sepals about 3 mm (0.12 in) long and five elliptical, white petals with a pink midline and 7–9 mm (0.28–0.35 in) long. The ten stamens are free from each other and hairy.[2][3]
