3. Ostrya japonica Sarg.

The Silva of North America 9: 32 ( Sargent 1896). – O. ostrya var. japonica (Sarg.) C.K.Schneid., Illustriertes Handbuch der Laubholzkunde 1: 143 ( Schneider 1904) nom. inval. (tautonym). – Type: Japan, Hokkaido, Hill near Sapporo, 18 Sep. 1892, C.S. Sargent s.n. (syn-: GH00055441!); ibid., Oiwagi, 1861, C.J. Maximowicz s.n. (syn-: BM!, BR!, K000859914!, L!, M-0265487!, P06809338!, P06811038!, W1886–1595!); ibid., Nambo, 1865, S. Tschonoski s.n. (syn-: K0000859913!, P06811037!); ibid., in sylvis frondosis circa lacum Konoma (syn-: not localized); cult. in Arnold Arboretum from seeds sent from Japan by H. Mayr (syn-: not localized). – Note: the name O. japonica Sarg. was only accepted by the author in the 1896 publication. Before, Sargent (1893, 1894) initially expressed certainty on the distinctness “In the forests of Yezo I felt no doubt of its specific distinctness […] all, things considered, it is, perhaps, best to consider the Japanese tree as specifically distinct”. However, just in the next sentence, he weakened his opinion stating “Only after it has been grown here during many years side by side with the American species will it be possible to reach any opinion on this subject worthy of much consideration. If it proves to be distinct it should bear the name of Ostrya Japonica ”. According to Art. 36.1. b ( McNeill et al. 2012), the two early publications ( Sargent 1893, 1894) cannot be considered as a valid publication of O. japonica . In 1896, however, Sargent accepted the Japanese collections as fully distinct and formalized the name.
