摘　　要：描述了湖北省长阳县资丘镇淋湘溪剖面下石炭统高骊山组的两种亚鳞木属(Sublepidodendron)植物——奇异亚鳞木(S.mirabile)和松滋亚鳞木(S.songziense)以及相关的生殖器官和根器官。重新认识了这两个种的叶座形态,进一步确认了亚鳞木属的整体植物性状。详细比较了奇异亚鳞木、松滋亚鳞木和葛利普亚鳞木的生物学特征,讨论了我国亚鳞木属的分类,并提出了新的归并方案。Sublepidodendron mirabile, S. songziense, correlative strobilus and rhizomorph are described from the Lower Carboniferous Gaolishan Formation in Linxiangxi Section, Ziqiu Town, Changyang County of Hubei Province. Morphology of leaf cushions of these two Sublepidodendron species are reinvestigated, and the whole-plant concept of Sublepidodendron is further confirmed. The biological features of S. mirabile, S. songziense and S. grabau/ are compared in detail, the taxonomy of Sublepidodendron in China is discussed, and a new grouping scheme is proposed.
