1h. Carpinus betulus ‘ Columnaris ’ C. betulus [unranked] columnaris Beissn., Mitteilungen der Deutschen dendrologischen Gesellschaft 8: 136(Beissner1899b).– C.betulus f. columnaris (Beissn.) Schelle, Handbuch der Laubholzbenennung: 48 (Beissner et al. 1903). – C. betulus var. columnaris (Beissn.) Bean, Trees and Shrubs, Hardy in the British Isles 1: 294 (Bean 1914). – Original citation: “In the gardens of Fürst Lobkowitz [Ferdinand Zdenko von Lobkowitz] at Schloss Eisenberg [Jezeří Castle, Czech Republic]”. – Type: not localized. – Note: according to Beissner et al. (1903), this cultivar was reported for the first time in a garden catalogue of the Späth’sche Baumschule in Berlin, Germany, in 1891, but the present authors could not verify if that publication contains a valid description. Although neither Beissner et al. (1903) nor Bean (1914) refer to Beissner (1899b), they all refer to a cultivar with erect branches forming a slender crown, so their names can be considered as new combinations (Art. 41.4.; McNeill et al. 2012).
