چکیده انگلیسی
The specimen of Leclercqia complexa previously described by Geng from the Early Devonian Pingyipu Group of Sichuan Province, South China was re-investigated. The result demonstrated that the plant bears three-dimensional microphylls with as many as 12 segments and adaxial, oval-elongate sporangia, showing a more complicated morphology than any other taxon of the order Protolepidodendrales. Although new observations do not confirm the previous designation to Leclercqia, it is not appropriate to establish a new taxon based on the only single poorly preserved specimen.
