| Abstract: | A new genus of Opiliaceae, Yunnanopilia is described from the 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 in the Kam-Yunnania Ancient Landmass. This indicates that the Opiliaceae may also be orginated in the Kam-Yunnania. |
