The flowers are collected in 4-11 in sessile umbrellas with several small bract leaves at the base. Pedicels 0.8-1.8 cm long, glabrous or pubescent. Bracts falling off early, very small. The flowers are 5-9 mm in diameter, with a bare hypanthium. Petals in number 5, almost rounded to obovate, white. The sepals are triangular, sharp, with fruits straight. Stamens in the amount of about 20, slightly shorter than the petals.
