Ulmus ‘Louis van Houtte’ (Syn. Ulmus ‘Vanhouttei’) is believed to have been first cultivated in Ghent Belgium circa 1863. It was once thought a cultivar of English Elm Ulmus procera though this derivation has long been questioned; W. J. Bean called it an elm of uncertain status. It was first mentioned by Deegen in Ill. Monatsch. Gartenb. 5: 103 1886. Its dissimilarity from the type and its Belgian provenance make the Ulmus procera attribution unlikely.
