| 英文摘要 | A number of Ephedroid macrofossils have been described from the Early Cretaceous in the last decade, indicating huge diversity of early Ephedraceae. However, relationships among these fossils and modern Ephedra remain ambiguous. This study proposes a new systematic classification of the family at the generic level based on the reduction and sterilization evolutionary hypothesis of female reproductive organs. Two subfamilies and two tribes are described as new to science. In this new classification, the family Ephedraceae consists of two subfamilies: Siphonospermoideae Y. Yang subfam. nov. and Ephedroideae Y. Yang subfam. nov., and the latter subfamily is divided again into two tribes: Liaoxieae Y. Yang trib. nov. and Ephedreae Y. Yang trib. nov. Ten genera are included in the new classification, and two genera are listed as doubtful due to their taxonomic characters being insufficient to place them in Ephedraceae. |
