The Davey Elm, Ulmus × hollandica 'Daveyi', is an English hybrid cultivar of unknown specific origin, generally restricted to the valleys of Cornwall.

[3][4][5][6] Photographs often show this tree in its windswept coastal form; inland its shape resembles more closely its putative Wych Elm parent, though with a denser crown.

A number of mature specimens are known to survive in south-west England, notably around Gulval, Newquay, the Roseland and St Kew in Cornwall.

The UK TROBI Champion grows in the grounds of Holne Park House on the southern edge of Dartmoor.

Another large tree grows in woodland behind Lancaster Avenue at Goodrington; when last measured in 2004 it was 22 m high by 100 cm d.b.h.
