5a. Carpinus cordata Blume var. cordata

C. erosa Blume , Museum Botanicum Lugduno-Batavum 1 (20): 308 ( Blume 1851). – Original citation: “In Japoniâ.” – Type: Japan, s. coll. (lecto-, designated here: L0040895! ex herb. Siebold s.n.).

C. erosa var. microcarpa Hayashi , 林業試験場研̍報告 [Research Report of the Forestry Experiment Station] 57: 153 ( Hayashi 1952). – Type: Japan, Ezo [Hokkaido], Prov. Hiyama, Mt. Gamushi, 8 Aug. 1952, Y. Hayashi s.n. (holo-: TFM).

C. erosa var. velutina Hayashi , 林業試験場研̍報告 [Research Report of the Forestry Experiment Station] 57: 153 ( Hayashi 1955). – Type: Japan, Hondo, Prov. Rikuchiu, Yamagata in Kuji, 15 Aug. 1952, N. Karizumi s.n. (holo-: TFM).

Ostrya mandshurica Budischtschew ex Trautv., Trudy Imperatorskago S. -Peterburgskago Botaniceskago Sada 9: 166 ( Trautvetter 1884). – Type: not localized, likely in LE.

C. cordata var. pseudojaponica H.J.P.Winkl., Botanische Jahrbücher für Systematik, Pflanzengeschichte und Pflanzengeographie 50 (Suppl.): 490 ( Winkler 1914). – C. erosa var. pseudojaponica Miyabe & Tatewaki , Bulletin of the Kyushu University Forests 21: 48 ( Tatewaki 1953) nom. inval. – C. erosa var. pseudojaponica (H.J.P.Winkl.) Miyabe & Kudo ex Horikawa, Acta Phytotaxonomica et Geobotanica 15 (1): 13 ( Horikawa 1953) nom. inval. pro syn. – Type: Japan, Insel Yesso, Mororan, Sep. 1904, U.J. Faurie 5775b (holo-: B†) [on U.J. Faurie 5775 in B marked with b]. – Note: this name is not mentioned in the World Checklist ( Govaerts & Frodin 1998) or in the WCSP (2016), but it is synonymized under C. cordata in the Flora of Japan ( Ohwi 1965). Tatewaki published the combination without reference to older literature or an own description, it is therefore invalid (Art. 41.3; McNeill et al. 2012). Horikawa referred to the combination as C. erosa var. pseudojaponica (H.J.P.Winkl.) Miyabe & Kudo in synonymy only. The combination may have been published in Icones of the essential forest trees of Hokkaido ( Miyabe et al. 1920 –1932) though, but the present authors did not have access for verification

C. cordata var. faurieana H.J.P.Winkl., Botanische Jahrbücher für Systematik, Pflanzengeschichte und Pflanzengeographie 50 (Suppl.): 489 ( Winkler 1914). – Type: Japan, Insel Yesso, Sapporo, Jun. 1891, U.J. Faurie 7111 (lecto-, designated here: P06747141!). – Additional type material: Japan, Iwanai, Sep. 1904, U.J. Faurie 5777 (syn-: A00033752!, BM000580426!). – Note: this name is not mentioned in the World Checklist ( Govaerts & Frodin 1998) or the WCSP (2016). Based on the subglabrous leaves and the locus classicus being on Hokkaido, it may well represent a distinct taxon.

C. cordata var. robusta H.J.P.Winkl., Botanische Jahrbücher für Systematik, Pflanzengeschichte und Pflanzengeographie 50 (Suppl.): 489 ( Winkler 1914). – Type: Japan, Insel Yesso, Mororan, Sep. 1904, U.J. Faurie 5775 (syn-: BM000580424!, E!). – Note: this name is not mentioned in the World Checklist ( Govaerts & Frodin 1998) or the WCSP (2016). As for C. cordata var. faurieana H.J.P.Winkl. it is unlikely that this name is synonymous with the other accepted varieties because of the relatively subglabrous nature and the locus classicus being on Hokkaido instead of the Asian mainland.

Kiev [Mémoires de la Classe des Sciences Physiques et Mathématiques de l’Académie des Sciences de l’Ukraine] 15 (1): 70 ( Radde-Fomina 1929). – Original citation: “Wladiwostok 1864 Budischczev [s.n.]! «Suchaja Padi» in viciniis pag.
