摘要	Problematospermum is a distinctive but enigmatic seed known mainly from the Jurassic and Cretaceous sediments. Numerous new specimens of Problematospermum ovale from two localities in the Middle Jurassic Jiulongshan Formation of China (Sanjiaocheng Village in western Liaoning and Daohugou Village in eastern Inner Mongolia) provide improved information on the structure of Problematospermum. It has an ovoid body with a long apical tube and bears a tuft of filamentous appendages at the base. While Problematospermum was interpreted previously as a disseminule of an angiosperm or angiosperm-like plant, the new specimens show closer similarities to seeds of the Bennettitales, Erdtmanithecales, and Gnetales. However, the unusual features of Problematospermum imply pollination and dispersal biology different from what has so far been known for key lineages of seed plants.
