Newly collected material of Austrohamia acanthobractea is re-described from the Jurassic Daohugou flora,from Ningcheng County of Inner Mongolia,China.The description is emended and completed based on a single well-preserved leafy shoot and twigs bearing ovulate cones and pollen cones.The twigs are densely covered by helically arranged linear-oblong leaves that are spread as two lateral ranks in one plane.Pollen cones are singly borne on ultimate branches,elliptical,with each bearing at least 14 spirally arranged subtending leaves.Ovulate cones are terminal and solitary,subglobose at the immature stage and cylindrical-ovoid at the mature stage,with numerous helically arranged bract-scale complexes.The complex consists of fused bract and ovulate scales,and each contains approximately 2 ovules at the base of its adaxial surface.Furthermore,germinating pollen grains and associated pollen tubes,archegonia,and germinating pollen grains,as well as an entire flask-shaped ovule undergoing the pollination process,were observed in the bract-scale complexes after maceration.All new discoveries apply to the pollination mechanism,which suggests that the present material was in the process of pollination prior to fossilization.In this context,the complete pollination process of A.acanthobractea is reconstructed based on the mechanism of pollination.The results show that the pollination process observed in the present species falls in between those of modem Cupressaceae and those of modem Pinaceae and Podocarpaceae.
