| 英文摘要 | This study reports the first record of Pagiophyllum maculosum in China, based on well-preserved specimens with attached reproductive structures, enabling unambiguous assignment to the Cheirolepidiaceae. The fossils include leafy shoots with cuticle, male cones, and female cones containing seeds. The penultimate and ultimate shoots bear helically arranged leaves with 2-3 parastichies. Leaves are hypostomatic, with stomata arranged in distinct rows and lacking papillae on the epidermis. Stomatal complexes are elliptic with 4-6 subsidiary cells; epidermal cells range from rectangular to irregular polygons. Female cones are elliptical, comprising 36-40 helically arranged bract-scale complexes. Pollen cones are subspheroidal with peltate microsporophylls. These specimens provide detailed morphological and anatomical features, allowing us to make a whole-plant reconstruction. |
