根据叶形态和表皮特征描述了产于酒泉盆地早白垩世中沟组的Pagiophyllum compressum（Deng and Lu）。扁叶蕨叶片紧密排列，螺旋状贴伏在末级枝上，呈叠瓦状。表皮细胞为方形或长方形，周壁无乳突。气孔器椭圆形，由4-7个附属细胞组成，排列在叶片中部，纵列2 - 3列。根据形态特征的聚类分析，本标本可能与南洋杉科（Araucariaceae）有关。通过总结晚侏罗世和白垩纪全球Pagiophyllum的分布，发现Pagiophyllum既可以生活在热带-赤道炎热干旱带，也可以生活在中高纬度湿润气候带，证实了Pagiophyllum具有广泛的栖息地。
Pagiophyllum compressum (Deng and Lu) was described based on the leaf morphological and cuticular features from the Lower Cretaceous (late Aptian—early Albian) Zhonggou Formation of Jiuquan Basin, Gansu Province, North-west China. P. compressum has helically and tightly arranged leaves appressed on the ultimate shoots, which are imbricated shapes. The epidermal cells are square or rectangular, without papillae on the periclinal walls. The stomatal apparatus is elliptic and composed of 4–7 subsidiary cells arranged in two or three longitudinal rows on the middle part of the leaves. The present specimens may be related to Araucariaceae based on the cluster analysis of morphological features. By summarizing the global distribution of the Pagiophyllum in the Late Jurassic and Cretaceous, it has been found that Pagiophyllum can live in both tropical-equatorial hot arid belt and humid climate zone of middle and high latitudes, confirming that Pagiophyllum has an extensive habitat.
