A note on geographical and stratigraphical distribution of Jurinodendron in China

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.
