Fossil plants from the carbonaceous shale of upper part of the Lower Carboniferous Jiujialu Formation in Lindai bauxite deposit fill a gap regarding the distribution of Early Carboniferous flora in Central Guizhou Province. Here the Lindai plant assemblage is systematically described, and its composition and geological age are discussed. Research demonstrates that 9 species in 6 genera of the fossil plants are discovered in this study, and they belong to lycopsids, sphenopsids and ferns, respectively. Based on the analysis of the floral composition, the geological age of the Lindai plant assemblage belongs to the Early Carboniferous Viséan. The discovery of Lindai plant assemblage not only provides a new fossil evidence to restrict the age of bauxite deposits in Lower Carboniferous Jiujialu Formation of Central Guizhou Province, but also has great significance to further research the palaeoecological setting and floral evolution during the Early Carboniferous.

贵州中部九家楼组的维桑化石植物：对铝土矿年龄和古环境的影响

林地铝土矿下石炭统旧家楼组上部碳质页岩的化石植物填补了黔中地区早期石炭纪植物区系的空白。在此系统地描述了Lindai植物组合，并讨论了其组成和地质年龄。研究表明，在该化石植物的6个属中发现了9种，分别属于番茄红素类，蝶类和蕨类。根据花的组成分析，Lindai植物组合的地质年龄属于早期石炭纪Viséan。Lindai植物组合的发现不仅为限制贵州中部下石炭统旧家楼组铝土矿的沉积提供了新的化石证据，
