Abstract: A new genus of Opiliaceae,Yunnanopilia is described fromthe Red River Valley,South-Central Yunnan Plateau,China. This genus is a primitive one in the Opiliaceae by having hermaphrodite flowers in large panicles,and may be the ancestry type of both Lepionurus,Melientha and Champereia. It seems that this genus may be originated inthe Kam-Yunnania Ancient Landmass. This indicates that the Opiliaceae may also be orginated in the Kam-Yunnania.
