It is a circle with five fertile stamens present. The stamens are bald. Two to three, rarely up to five carpels are constant above a ( syncarp ), one or two incomplete to fünfkammerigen ovary adherent who is bald or hairy fluffy. There are usually many, sometimes only one to four ovules in parietal placentation available. The short, most durable stylus may be two to five shared.
