The flowers are white and borne singly or in pairs on the ends of branchlets. The pedicels are about 1 mm (0.039 in) long, thick and densely covered with rust-coloured scales. The sepals are about 1.5 mm (0.059 in) long and joined at the base and covered with rust-coloured scales on the outside. Flowering occurs in July.[2][3]
