Ulmus × hollandica 'Commelin' is a Dutch hybrid cultivar released for sale in 1960. The tree was raised at Baarn as clone 274 by the Foundation Willie Commelin Scholten Phytopathological Laboratory in 1940, from a crossing of Ulmus × hollandica 'Vegeta' and clone 1, an Ulmus minor selected from a 1929 elm seedlings lot obtained from the Barbier nursery, Orléans.
The tree succumbed to Dutch elm disease and was felled in 1968. A ring count established that it had begun life in the year 1701. [61] The "Great Elm Tree" at Phillips Academy in Andover, Massachusetts is believed to have been standing for at least 200 years. It is being well cared for and receives regular treatments for Dutch elm disease. [62]
FOTE also raises funds to support research into ways to combat insect attack, Elm Leaf Beetle, and prevent the spread of Dutch Elm Disease if it arrives in Australia. It encourages the public to register elm trees that they see around their neighbourhood. Once an elm tree has been positively identified, it is added to the National Register of Elms.
The earliest known references are Dutch and German, the first by de Vos in Handboek tot de praktische kennis der voornaamste boomen (1890).

With a girth of 6.9 m (22.6 ft) and a height of 40 metres (130 ft), the Ulmus × hollandica hybrid elm on Great Saling Green, Great Saling, near Braintree, Essex, reckoned at least 350 years old, [25] was reputedly the largest elm in England, before succumbing to Dutch Elm Disease in the 1980s; [26] Elwes and Henry (1913) misidentified it as U ...
The ‘Dutch’ elm quickly became popular in eighteenth-century estate plantations in England, survivors today being naturalised relics of this planting fashion; but the tree was always rare in the Netherlands, where from the eighteenth century hollandse iep (Holland elm) meant the widely planted hybrid Ulmus × hollandica Belgica (Belgian Elm). [2]
The starting-points for List of elm cultivars, hybrids and hybrid cultivars were fourfold: (1) Green's 'Registration of Cultivar Names in Ulmus ' (1964), [1] based on the contemporary nomenclature of elm species and wild hybrids; (2) Krüssmann's confirmation or correction of cultivar-names in his monumental Handbuch der Laubgehölze (1976); [2] (3) Heybroek's table of Netherlands research ...
