木兰目（Austrobaileyaceae，Degeneriaceae，Eupomatiaceae和Himantandraceae）中的内退化雄蕊（位于雄蕊和心皮之间）不仅是退化的雄蕊，而且是精致的器官。在Eupomatiaceae、Himantandraceae中，可能还有Degeneriaceae中，它们有自己的分泌结构，但不出现在雄蕊上。它们在植物生物学中起着重要的作用。它们对花的着色模式有贡献;它们通过它们的位置和运动来影响雌雄异体;它们为授粉甲虫提供庇护所和食物组织和食物分泌物;它们分泌有气味的油、粘液（可能是为了花粉粘附）和水或花蜜。对于Himantandraceae一个新的分泌区的基础上的内部退化雄蕊的描述。这些复杂的内退化雄蕊是原始花型的极端特化。它们在被子植物的更高级的亚纲中没有对应物。
The inner staminodes (between stamens and carpels) in some relic Magnoliales (Austrobaileyaceae, Degeneriaceae, Eupomatiaceae and Himantandraceae) are not just reduced stamens; they are elaborate organs. In Eupomatiaceae, Himantandraceae, and probably Degeneriaceae they have their own secretory structures which do not occur on the stamens. These play an important role in floral biology. They contribute to the floral coloration pattern; they effect herkogamy by their position and by movements; they provide shelter and food tissue and food secretions for pollinating beetles; they secrete odoriferous oils, mucilage (probably for pollen adherence) and water or nectar. For the Himantandraceae a new secretory region on the base of the inner staminode is described. These complicated inner staminodes are extreme specializations of primitive floral types. They have no counterparts in more advanced subclasses of the angiosperms.
