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: ; 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.
Trichotomous branching
At least one member of the genus, Edgeworthia chrysantha, has the extremely unusual ability to branch trichotomously - the apical meristem forming the end of each stem splits into three sections at once. This trait is shared with no other known flowering plant.
