Flowers solitary (rarely 3) in distal leaf-axils; pedicel 5–18 mm long, often horizontal with distal end and flower erect. Calyx (2–)3–6 mm long, densely grey-pubescent with antrorse hairs, tube c. half as long as or equal to lobes; corolla white, tube slightly shorter than calyx, mid-lobe (2–)5–9 mm long, pubescent externally; stamens c.
