Racemes pedunculate, umbellate, 1.5–2(–3) × 1.5–2 cm, up to 20-flowered; pedicels 5–8 mm, glabrous; bracts linear, small, caducous. Flowers 5–7 mm in diam. Hypanthium campanulate, glabrous abaxially. Sepals triangular, 1–2 × 1.5–2 mm, erect or semispreading in fruit, apex acute. Petals white, obovate or suborbicular, 2–3 mm, about as broad as long, base shortly clawed, apex obtuse or emarginate. Stamens ca. 20, slightly shorter than to subequaling petals. Disk distinct, annular, 10-lobed. Carpels pubescent; styles shorter than stamens.
