Inflorescences axillary, glomerulous to laxly cymose, 0.75-2 cm long, up to c. 10-flowered; pedicels slender, 1.5-6 mm. Sepals mostly acute, 1-1.5 mm long, outside glabrous or minutely pubescent. Corolla 2-4 mm long, lobes blunt to acute, 1½-2.25 mm, glabrous (rarely outside papillose-tomentose). Stamens mostly shortly patent-hairy, filaments very short to ¾ mm, anthers ¾-1 2/3 mm, appendage of the connective up to about half as long.
