Origin
England

The Wych Elm Ulmus glabra cultivar 'Crispa' Loudon, the Fernleaf Elm, is a slow-growing tree with narrow, linear to oblanceolate leaves up to 9 cm long by 3.5 cm broad, distinctively wrinkled and with numerous incised curved teeth [1]. Most commonly a small tree with pendulous branches, it was once to be found across Britain, notably at Kew Gardens [2] [3]. A specimen at the Ryston Hall[3], Norfolk, arboretum, obtained from the Späth nursery in Berlin[4], was killed by the earlier strain of Dutch elm disease prevalent in the 1930s.

One tree is known to survive at Birr Castle, County Offaly, in the centre of Éire, and is listed as the Irish champion tree, although some authorities have identified it as the Exeter Elm. The British champion, at Chiltley Place, Liphook, in Hampshire was last recorded in 1960 and has been long lost, either to the development of the site or to Dutch elm disease; no other specimens are known in the UK [5]. The only other living tree known is in Latvia. However, 'Crispa' was marketed in Poland in the 19th century by the Ulrich nursery [6], Warsaw, and others may still survive elsewhere in Eastern Europe. Introduced to Australia, the tree was listed by nurseries there in the early 20th century, but there are no records of any survivors [7].
