研究我国云南中泥盆世晚期西冲组的一种细小植物Psilophytonstriatumsp .nov .,它具有二歧分叉光滑轴和生殖枝 ,生殖枝由三次等二歧分叉枝系和族生孢子囊组成。枝系末端着生两对直立孢子囊。根据对已有材料的分析 ,宜将华南中泥盆世晚期植物组合改名为Lepidodendropsisarborescense Minarodendroncathaysiense Eocladoxylonminutum (LME)组合。它以石松类植物为主 ,共生有“真蕨植物”和三枝蕨类 ,分为小形树状植物和地面植物两个生态系统。同时 ,与世界上同期植物群进行了对比
To study the Psilophytonstriatum sp .nov., A small plant in the late Middle Devonian of Yunnan, China, which has a bifurcated bifurcation axis and a reproductive branch. The reproductive branch is composed of three isobaric bifurcation branches and a conidia . Two pairs of upright sporocysts at the end of branches. Based on the analysis of the existing materials, it is advisable to rename the Late Mid-Devidian plant assemblage in Lepidodendropsisarborescense Minarodendron cathaysiense Eocladoxylonminutum (LME) combination. It is predominantly Lycopodium species, symbiosis “true fern plant” and three branches of ferns, divided into small dendritic plants and ground plants two ecosystems. At the same time, it is compared with the flora of the same period in the world
