KINGDONIA, EMBRYOLOGY AND ITS SYSTEMATIC SIGNIFICANCE
独叶草属的胚胎学及其系统学意义

The embryological studies show that Kingdonia is similar to Circaeaster while different from other members of the Ranunculales (sensu Takhtajan, 1980) in development of endosperm and embryo. We consider that there is close systematic relationship between Kingdonia and Circaeaster.
