They have four 1 to 2.2 centimeters long and 1 to 2.2 centimeters wide, white, broadly obovate to rounded, entire sepals . The numerous, creamy white fertile flowers have a 1 to 1.5 millimeter long, bell-shaped calyx tube with 0.5 to 0.8 millimeter long, broadly ovoid to triangular calyx teeth. The petals are connected like a hood at the top. The nine to 18 stamens are of unequal length, the anthers are small and rounded. The ovary is subordinate, the two or rarely three styles are bent back and are about 1.5 millimeters long on the fruit.
