Abstract The paper provides in situ records of eight species of spore genera Punctatosporites, Laevigatosporites, Latosporites, Torispora, Cyclogranisporites and Thymospora macerated from fertile plant specimens of genera Asterotheca (A. sp. A and B), Cyathocarpus (C. arborea, C. aff. arborea and Cyathocarpus hemiteloides) and Acitheca (A. ambigua) which come from the Bolsovian to Stephanian B of the Kladno-Rakovnik and Pilsen basins, Czech Republic and Scolecopteris hemiteloides from the Permian (Roetligendes), Dohlener Becken, Germany. It is possible to recognize seven morphological types of in situ spores isolated from Paleozoic marattialean ferns. Most of them produced monolete others trilete spores. Sometimes sporangia contain only one morphological type of the spores, sometimes in situ spores are comparable with more dispersed species of two or even four genera. Palynological grouping of Paleozoic marattialeans is based on in situ spores isolated from 124 parent plant species.

古生代marattialean miospores的孢粉学分组

摘要 本文提供了从 Asterotheca (A. sp. A 和 B)、Cyathocarpus (C. arborea) 属的可育植物标本中浸渍的 8 种孢子属 Punctatosporites、Laevigatosporites、Latosporites、Torisporites、Cyclogranisporites 和 Thymospora 的原位记录。 aff. arborea 和 Cyathocarpus hemiteloides) 和 Acitheca (A. ambigua)，它们来自捷克共和国 Kladno-Rakovnik 和 Pilsen 盆地的 Bolsovian 到 Stephanian B，以及德国 Dohlener Becken 的二叠纪 (Roetligendes) 的 Scolecopteris hemiteloides。可以识别从古生代 Marattialean 蕨类植物中分离出的 7 种形态类型的原位孢子。他们中的大多数产生了 monolete 其他 trilete 孢子。有时孢子囊仅包含一种形态类型的孢子，有时原位孢子可与更分散的两个甚至四个属的物种相媲美。古生代 marattialeans 的孢粉学分组基于从 124 种亲本植物物种中分离出的原位孢子。
