大量茨康类压型化石在鄂尔多斯盆地中侏罗世含煤地层延安组中被发现。本文根据叶外部形态和表皮构造特征，首次发现拟刺葵属的苦戈维尔叶亚属Phoenicopsis （ Culgoweria），并建立了鄂尔多斯拟刺葵（苦戈维尔叶）（新种） Phoenicopsis （ Culgowaria） ordosensis sp.nov。新种代表了该亚属在我国中侏罗世的第一个化石记录，为研究其地质、地理分布提供了新的证据，也为研究该类植物在欧亚大陆中侏罗世的多样性增添了新内容。

A large number of compressions of Czekanowskialean leaves were collected from the Middle Juras-sic coal-bearing Yan'an Formation of the Ordos Basin , Inner Mongolia .Subgenus Phoenicopsis ( Culgoweria ) is found based on leaf gross morphology and epidermal characters for the first time .A new species , Phoenicopsis ( Culgowaria) ordosensis sp.nov.is the first record of the subgenus Phoenicopsis ( Culgoweria) from the Middle Ju-rassic in China .The new finding is significant for studying geological and geographical distribution of this subge -nus, and for better understanding of the diversity of the subgenus during the Middle Jurassic in Eurasia .
