Premise: Emmenopterys henryi is a species of flowering plant in the Rubiaceae family. It is found in the temperate parts of central and southern China and in Vietnam. It is a deciduous tree with opposite leaves and can attain heights of 45 m and grow to be 1000 years old. The epithet is named after the Irish botanist and sinologist Augustine Henry.
