摘　　要：现已查明,化石圆印木属CyclostigmaHaughton,1859一名是现代植物的晚出同名,应该废弃使用。古植物学者Doweld建议用JurinodendronDoweld,2001来取代它,并对该属在国外的分布作了具体的报道。笔者就Jurinodendron在中国的地质地理分布作了详细的阐述。Since Russian palaeobotanist had found the term Cyclostigma which argued for centuries is a homonym in modern botany during his study of nomenclature of fossil plants,but there was no any Chinese information in his publication of the distributions of Jurinodendron which he proposed to replace Cyclostigma in the world.So this paper just shows the geographical and stratigraphical distribution of Jurinodendron in China after a careful study in the genus as a supplement to whole the distribution of Jurinodendron in the world.
