Abstract
Marattia aganzhenensis sp. nov. from the Lower Jurassic Daxigou Formation of Lanzhou, Gansu, China, is the
second species of Marattia known in fertile structure from China, in addition to Marattia asiatica. The new
species demonstrates the variability of the genus through its distinct character states. This new species is
distinguished by the absence of venuli recurrentes, the shorter synangia, exclusively monolete spores without
surface ornamentation, and the low number of spores produced per sporangium.
