The specimen was collected from the Late Paleozoic "Longtan Formation” of Jiangle county, Fujian Province of China. It was originally determined to the genus Gigantonoclea and named as G. cardiophylla Zhu et Geng by one of the present authors and his colleague some times ago. In view of its venation being trinervious and that the incompletely duplicated net-like veins are close to those of gigantopterides and the leaf bears sori on its back. Upon reconsideration it was renamed by the authors as Trinerviopteris cardiophyUa (Zhu et Geng) Zhu gen. et comb. nov. At the same time. the authors have confirmed that it is a kind of true fern. In association with the new taxon there are Sphenophyllum emarginatum, Bowmanites lascus, Lobatannularia lingulata, Chansitheca pcdaeosilvana, Ch. cf. kidstonii, Pecopteris anderssonii, P. echinata, P. taiyuanensis, P. unita, Danaeites mirabilis, Fascipteris densata, Cladophlebis permica, Compsopteris contracta, Gigantonoclea chingii, G. fukienensis, G. sp., G. sp., Gigantopteris cordata, G. nicotianaefolia, Taenioteris serrulata, T. szei, T. tingii, Radicites sp. 1, R. sp. 2 etc. The present flora is more simplified than the others which discovered from different areas in the same geological time. Based on the grouping of these fossil plants, the geological era of the present flora must be late Early Permian to early Late Permian. Moreover it is emphasized that the gigantopterides is only but an artificial compound taxon not only including seed ferns but also true ferns and others.
