TheDavey Elm,Ulmus × hollandica 'Daveyi', is an Englishhybridcultivar of unknown specific origin, generally restricted to the valleys ofCornwall. Its apparent south-west England provenance, along with its foliage and habit, suggest that it may be ahybrid ofWych Elm andCornish 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][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.[1]
The tree is susceptible toDutch elm disease.
A number of mature specimens are known to survive in south-west England, notably aroundGulval,Newquay, theRoseland andSt Kew in Cornwall.[1][7] The tree is not known to have been introduced to North America or Australasia, and is not in commerce in the UK.
The UKTROBI Champion grows in the grounds ofHolne Park House on the southern edge ofDartmoor. Discovered in 2017, it measured 30 m tall by 172 cm d.b.h. Another large tree grows in woodland behind Lancaster Avenue atGoodrington; when last measured in 2004 it was 22 m high by 100 cmd.b.h.[8]
The Davey Elm was named byAugustine Henry forFrederick Hamilton Davey (1868-1915), Cornish botanist and author of theFlora of Cornwall, first published in 1909 and reprinted in 1978.[5]
