Ulmus ×hollandica var. insularum
Also called Dutch Elm, Holland Elm
Ulmus × hollandica var. insularum was recognized as a biometrically distinct population of U. × hollandica endemic to all the Channel Islands and the Cotentin Peninsula of France by Richens and Jeffers in 1975. As of January 2025, Plants of the World Online did not accept this or any other varieties of U. × hollandica, treating them all as synonyms of the hybrid species.
As of 2015, the status of the tree in the Channel Islands following the arrival of Dutch elm disease was not recorded.
