摘要：
The marattialean fern Scolecopteris antarctica sp. nov. is described from early Middle Triassic silicified peat collected in Antarctica. The synangia are radial and borne on pecopterid-type pinnules; spores appear to be alete. This is the first report of the genus in Mesozoic sediments and suggests that modern marattialeans may not have been related to the Paleozoic forms.
