摘要：
This is the first reports of a few fossil monocotyledons, including Liaoxia chenii gen. et sp. now (belonging to Cyperaceae), Eragrosites changii gen. et sp. nov. (Gramineae) and a monocotyledonous leaf-shoot, obtained from the Late Jurassic Yixian Formation of western Liaoning Province, NE China. These fossils are the oldest known angiosperms in the world. It may be inferred that the earliest angiosperms probably appeared even earlier than the Late Jurassic.
