Flowers are borne in leaf-axils or leaf-opposed on lateral branches, in umbels carried on flower-cluster-stalk 3-8 cm long, velvet-hairy or hairless. Flower-stalks are 1-3 mm, papillose or becoming hairless. Buds are elliptic or obovoid-elliptic, 2-2.5 mm, tip rounded. Calyx are shallow and saucer-shaped, hairless, margin wavy.
