Descrição: Morphological indices of vegetative organs or reproductive organs, which are often used to analyze the evolution and classify Clematis, indicate that Clematis serratifolia and C. glauca could be related members at similar evolutionary levels. However, this assumption differs with phylogenetic studies based on genetics. Embryonic characteristics, which are more stable, are commonly used to estimate the phylogeny and evolution of angiosperms. We studied the microsporogenesis, microgametogenesis, megasporogenesis and macrogametogenesis development of C. serratifolia, and compared the early embryological characteristics among C. serratifolia, C. serratifolia and other Clematis species reported to provide a reference for the taxonomy of the genus Clematis. Our results showed that C. serratifolia and C. glauca differ in megaspore formation and nucellus types suggesting that they have originated from different ancestors. The differences among Clematis were mainly found in the type of the anther wall development, tapetum, pollen grains, megaspore formation and nucellus types.
