本文描述了产于大同煤田南部吴家窑剖面的一个轮叶类植物新种Ａｎｎｕｌａｒｉａｐｅｒｍｉｃａｓｐ．ｎｏｖ．。其特征为：叶轮具明显上叶缺，叶多少向上弯曲，仅下部数枚叶直伸；脉粗，两侧具多条垂直于中脉之横纹。由于具稳定上叶隙的轮叶仅出现于二叠纪，因此新种的发现为该区晚古生代含煤地层的划分与对比提供了新的依据。 This article describes Annulariapermicasp, a new species of leaf-foliage plant produced in the section of Wujiayao, southern Datong coal field. nov . The utility model is characterized in that: the leaves of the leaves are obviously lacking in leaves, the leaves are slightly upwardly curved, and the leaves in the lower part are straight; the veins are thick, with a plurality of transverse stripes perpendicular to the midrib on both sides. The discovery of new species provides a new basis for the division and contrast of Late Paleozoic coal-bearing strata in this area because of the presence of stable upper-lobed blades only in the Permian.
