Abstract: The present paper deals with the exteral form and the cuticle structure of Ctenozamites drepanoides Chen et Duan sp. nov. The specimens were collected from the upper Triassic coal series of Liuzhi district, Guizhou province. Main characters of the new species: Leaf bipinnate, ultimate pinna lanceolate, pinnules drepaniform, entire, apex obtuse, pinnules arising from the upper side of pinna rachis. Cuticles rather thick. Stomatal apparatus haplocheilic, smaller, confined to the lower epidermis, scattered in the areas between veins, variably orientated, 70–80 per sq. mm.
Key words: Ctenozamites drepanoides, Upper Triassic
