The name Edgeworthia chrysantha was published a few weeks earlier in 1846 than E. papyrifera and therefore has priority. The oldest name, Magnolia tomentosa , was never generally taken up and was formally rejected to protect E. papyrifera. This means that Nakai’s E. tomentosa is also rejected. "Daphne papyrifera" is not a validly pub lished name: D. Don (Prodr. Fl. Nepal.: 68. 1825) merely cited "D. papyrifera Buchanan-Hamilton" as a synonym of D. odora; later, Siebold (Verh. Batav. Genootsch. Kunsten 12: 22. 1830) commented on the value of "D. papyrifera" for paper-making, referring to E. chrysantha as currently understood, but this is not acceptable as a validating description or diagnosis (see Art. 32.3 of the Vienna Code).
