Edgeworthia (paper bush) is a genus of plants in the family Thymelaeaceae. When the genus was first described, it was published twice in the same year (1841), in two separate publications: Plantarum vascularium genera: secundum ordines naturales digesta eorumque differentiae et affinitates tabulis diagnostacis expositae; and Denkschriften der Regensburgischen Botanischen Gesellschaft. The genus was named in honour of Michael Pakenham Edgeworth, an Irish-born botanist and official in the Bengal Civil Service, then stationed in India, and for his half-sister, writer Maria Edgeworth.
