Calyx teeth prominent , connate and persistent .

在雌花发育接近成熟时，萼片部分愈合，形成萼筒，萼片上部未合生的部分则发育成萼齿，此时在雌蕊的周围可见一轮退化雄蕊。

When the female flower become maturity , part of the sepals syncretize and form a calyx tube and the remains of sepals become calyx tooth . At this time , a cycle of staminodes could be seen around the base of gynoecia .
