Images of two new species of the Late Devonian seed Cosmosperma as Cosmosperma dicrana sp. nov. (A–C) and Cosmosperma lepta sp. nov. (D–G), based on specimens from Anhui and Zhejiang Provinces, South China. While the cupules of both new species feature prickles on their outer surface, they exhibit varied dimensions compared to the type species (H) and are borne on fertile branches with distinct patterns.
