Bot. Z. 66: 26, 30. 1916 Holotype :— Ulmus glabra Huds. Notes :—This name is automatically typified under Art. 22.6 of the ICN . Despite its archaic form, this name is legitimate under Art. 21.3 of the ICN , since it was not formed by adding the prefix “Eu-“ to the name of a genus but to the name of an included species.
