报道了产于中国二叠纪煤核中的 3种具解剖构造的鳞木类叶 ,它们都具双木质部束 ,与似封印叶属 (Sigil lariopsisScott)特征一致。与该属已有种进行了对比 ,确认它们为 3个新种 :产于山西太原西山煤田太原组上部 7号煤层 (早二叠世早期 )煤核中的山西似封印叶 (Sigillariopsisshanxiensissp .nov .)和太原似封印叶 (S .taiyuanensissp .nov .)以及产于贵州水城矿区汪家寨组 1号煤层 (晚二叠世晚期 )煤核中的贵州似封印叶 (Sigillariopsisguizhouensissp .nov .)。根据煤核中共生的鳞木类植物其他器官以及欧美植物区鳞木类植物的研究资料推断 ,它们可能属于封印木属 (SigillariaBrongniart)的叶。在国外 (主要是欧美植物区 ) ,封印木属植物主要分布于石炭纪 ,见于二叠纪的封印木很少。华夏植物区的封印木属过去很少发现 ,其叶和生殖器官均未报道过。本文是首次报道华夏植物区具解剖构造的封印木属的叶 ,它们的发现不仅丰富了华夏植物区封印木属植物的内容 ,而且对于研究封印木属的演化以及华夏植物区与欧美植物区鳞木类植物之间的关系也具有重要的意义。
Three anatomical scales were found in the Permian coal cores in China, with double xylem bundles, consistent with the Sigil lariopsisScott feature. In comparison with the genus of the genus, three new species were identified: Sigillariops lissiensisissiep. Nov., Which is produced in the coal core of No.7 coal seam (Early Permian) in the upper part of the Taiyuan Formation of the Xishan coal field in Taiyuan, Shanxi Province. ) And Taiyuan (S. Taiyuanensissp. Nov.), And Sigillariopsis guizhouensissp. Nov. In the coal core of No. 1 coal seam of Wangjiazhai Formation (late Late Permian) in Shuicheng, Guizhou Province. According to the research data of symbiotic scales of lignos and other species in the European and American flora, it is concluded that they may belong to the leaves of Sigillaria Brongniart. In foreign countries (mainly Europe and the United States plant area), seal woody plants are mainly distributed in the Carboniferous, found in the Permian seal wood rarely. In the past, sedums of the Huaxia Botanical Zone have rarely been found in the past, and none of their leaves and genital organs have been reported. This article is the first to report on the anatomical structure of the Huaxia flora with seal woody leaves, their discovery not only enriched the Huaxia flora Sealwood genus content, but also for the study of seal woody evolution and Huaxia flora and European and American plant scales The relationship between woody plants is also of great significance.
