Edgeworthia chrysantha (common names: Oriental Paperbush, Mitsumata[1] ) is a plant in the Thymelaeaceae family.[2]


The genus was named in honour of Michael Pakenham Edgeworth (1812–1881), an Irish-born Victorian amateur botanist. [3] The species name chrysantha derives from the Greek xrus meaning « golden » and enteron meaning « guts », with reference to the golden centre of the flowers.


Edgeworthia chrysantha is a deciduous shrub with dark green, leathery, single, alternate, lanceolate leaves, 8-13 cm long. It can reach a height of 2-2.5 m. Flowers are yellow and fragrant, in clusters at the branch tips. The flowering period extends from February to April. The bark fibres of this plants are used for making the handmade Japanese tissue called "mitsumata paper". Along with Kozo and Gambi it is used for making traditional Japanese paper or Washi.


This species can be found in south west China, Nepal and Japan.
