酒泉盆地下白垩统植物群可分为两个组合。赤金铺组上部的Athrotaxites-Solenites组合包括Solenites luanpingensis Wang，Pityocladus cf. Iwaianus（ishi）Chow，Pityocladus sp.和Athrotaxites berryi Bell，时代为早白垩世早期，反映湿润或半湿润气候。中沟组上部的Brachyphyllum-Pseudofrenelopsis组合以Sphenopteris sp.为代表，dalatzensis（Chow et Tsao）Cao ex Zhou，Cupressinocladus elegans（Chow）Chow，Cupressinocladus sp.，n.玉门厚叶藓，n.扁叶兰Pagiophyllum compressum sp. nov.，Pagiophyllum sp.，Ningshiaense Chow et Tsao、钝叶短叶藓（Brachyphyllum obtusum Chow et Tsao）、楼梯草属（Elatocladus sp.）Podozamites sp.和Carpolithus sp.显示早白垩世Aptian Albian期，气候干旱。
The Lower Cretaceous flora of the Jiuquan Basin, Gansu of Northwest China, is divided into two assemblages. Assemblage Athrotaxites-Solenites from the upper part of the Chijinpu Formation consists of Solenites luanpingensis Wang, Pityocladus cf. iwaianus (ishi) Chow, Pityocladus sp. and Athrotaxites berryi Bell, which is considered as early Early Cretaceous in age and it reflects humid or semi-humid climate. Assemblage Brachyphyllum-Pseudofrenelopsis from the upper part of the Zhonggou Formation represented by Sphenopteris sp., Pseudofrenelopsis dalatzensis (Chow et Tsao) Cao ex Zhou, Cupressinocladus elegans (Chow) Chow, Cupressinocladus sp., Pagiophyllum yumenense sp. nov., Pagiophyllum compressum sp. nov., Pagiophyllum sp., Brachyphyllum ningshiaense Chow et Tsao, Brachyphyllum obtusum Chow et Tsao, Elatocladus sp., Podozamites sp. and Carpolithus sp. shows Aptian Albian of Early Cretaceous and indicates arid climate.
