The Davey Elm Ulmus × hollandica 'Daveyi' is an English cultivar of unknown origin, generally restricted to the valleys of Cornwall. Its apparent South-West England provenance, along with its foliage and habit, suggest that it may be a hybrid between wych elm and Cornish elm.[1][2]

The wide-spreading, irregular branches support pendulous branchlets. The leaves are comparatively small, rarely exceeding 6 cm in length by 5 cm wide, with a glabrous upper surface.[3][4] Photographs often show this tree in its windswept coastal form; inland its shape resembles more closely its U. glabra parent, though with a denser crown.[5]
The tree is susceptible to Dutch elm disease.
A number of mature specimens are known to survive in south-west England, notably around Gulval, Newquay, the Roseland and St Kew in Cornwall.[6] The UK Champion Tree stands at Goodrington which, when last measured in 2004, was 22 m high and 100 cm d.b.h..[7] Other fine specimens can be found at Trenance Farm, St Newlyn East, Newquay. The tree is not known to have been introduced to North America or Australasia.
The Davey Elm was named by A. Henry for Frederick Hamilton Davey (1868-1915), Cornish botanist and author of the Flora of Cornwall, first published in 1909 and reprinted in 1978.
