本文全面介绍了苏格兰米德兰河谷迪南田（钙化砂岩组和下石灰岩组）中被认为具有地层学意义的小孢子物种的分布。在这些层中可以识别出五个小孢子并发范围带：Tripartites vetustus-Rotaspora fracta （VF）带Raistrickia nigra - triquitres marginatus （NM）带Perotrilites tessellatus-Schulzospora campyloptera （TC）带Lycospora pusilla （Pu）带Schopfites claviger-Auroraspora macra （CM）带这些带在研究剖面中的分布为一系列岩石的对比提供了一种方法。它们大多是非海相的，以缺乏地层学上有用的宏观化石和明显的相和厚度变化而闻名。在诺森伯兰海槽的下石炭统岩石剖面中也证实了该带，从而为两个地区之间的对比提供了一种潜在的方法。描述了两种新属，条纹石属和双环纹石属，并修正了一种三角石属。描述了15个新种和1个新型，3个重组种和3个修正种。图示了有代表性的小孢子区组合。
Synopsis This paper provides a comprehensive account of the distribution of miospore species which are considered to be stratigraphically significant in the Dinantian (Calciferous Sandstone Measures and Lower Limestone Group) of the Midland Valley of Scotland. Five miospore concurrent range zones are recognised in these beds: Tripartites vetustus—Rotaspora fracta (VF) Zone Raistrickia nigra—Triquitrites marginatus (NM) Zone Perotrilites tessellatus—Schulzospora campyloptera (TC) Zone Lycospora pusilla (Pu) Zone Schopfites claviger—Auroraspora macra (CM) Zone The distribution of these zones in the sections studied provides a method of correlation in a series of rocks, which are largely of non-marine origin and notable for their lack of stratigraphically useful macrofossils and for marked variations in facies and thickness. The zones have also been proved in sections of Lower Carboniferous rocks in the Northumbrian trough, thereby providing a potential method of correlation between the two areas. Two new genera, Colatisporites and Biannulatisphaerites, are described and one Tricidarisporites emended. Fifteen new species and one new type are described, three species recombined and three emended. Representative assemblages of the miospore zones are illustrated.
