Sinojackia
Sinojackia is a genus of five to eight species of flowering plants in the family Styracaceae, all endemic to China. The species are deciduous shrubs or small trees growing to 4–12 m tall. During a presentation on Chinese plant species at Chiba University's Dept. Of Horticulture on October 27, 2017, botanist Mikinori Ogisu informed the audience that less than 20 "Sinojackia sarcocarpa" remain in the wild. He also said he had walked in the mountains with a local and found the species.
