The European White Elm cultivar Ulmus laevis 'Colorans' was listed as U. effusa (: laevis) var. colorans by in Petzold & Kirchner, Arboretum Muscaviense (1864). Peter Shaw Green (1964) suggested that 's U. campestris Linn. rubescens, described in Gartenflora (1871), by its name a wych elm cultivar with "reddening leaves", from Yelagin Island, may have been an earlier listing of a 'Colorans'-type U. laevis under a mistaken species name.
