Edgeworthia chrysantha or Edgeworthia papyrifera is also commonly known as Mitsumata, Paperbush, or Oriental PaperBush. It is part of the Thymelaeaceae family of plants. It is native to China. It was named after Michael Pakenham Edgeworth (1812-1881), an Irish botanist, and chrysantha is a composite word from Greek chrysos and anthos which means golden flowers.
The Japanese name Mistumata is due to the paper that is made from its bark. Edgeworthia chrysantha is a deciduous shrub. It flowers in early spring before the leaves appear.
