- W2350553673 abstract "Some fossil remains of morphogenus sterile fern foliage Cladophlebis were collected from the Lower Cretaceous Bantou Formation,Yong'an City,Fujian Province.The gross morphological structure and microstructure of cuticles are studied.These fronds are at least bipinnate,main rachis broad,pinnules small,with entire margin crowdedly attached to the rachis with the whole basis.Their midveins are moderately thick,and the secondary veins at the margin are dense,mostly with a single bifurcation.The upper epidermis is free from stomata,with an indistinct outline of cells,and trichomes can be found sometimes.The stomata on the lower epidermis are longitudinally arranged.The epidermal cells are oblong or elongated,anticlinal cell walls straight or slightly undulant and moderately thick,periclinal walls slightly wrinkled.Stomata are mainly circinal,with well-developed stomata ledges.Guard cells are sunken with weak cutinization,and subsidiary cells are not distinct.The cuticular features described above fill in a gap of the epidermic structure about the genus.Additionally,comparison of epidermic features between present fossils and recent Osmunda joponsica,as well as some filices fossils is carried out.The comparison of gross morphology and cuticular features shows that specimens studied are of a new species and is named as Cladophlebis yonganensis Dai et B.N.Sun,sp.nov.,and it is concluded that the fossils studied represent a certain extinct plant of filices." @default.
