The small flowers appear singly or in more or less rich cymes. The petals are purple to white. The filamentous staminodes surround the stamens in a central cone. The nectary forms a lophomorphen ring.

Damper blades are missing or they are narrow. The closure body are formed as a hook, hood or chopsticks. The fruits contain brown seeds, which are smooth to papillose. The seeds are 0.6 to 1.6 mm long and 0.4 to 1.2 millimeters wide.
