text: # Ulmus × hollandica 'Viscosa'
  
  The hybrid elm Ulmus × hollandica 'Viscosa' is probably one of a number of cultivars arising from the crossing of the Wych Elm U. glabra with a variety of Field Elm U. minor. The tree was listed by Loddiges, (Hackney, London) in his catalogue of 1836 and two years later by Loudon in Arboretum et Fruticetum Britannicum 3: 1378, 1838, as U. viscosa. An early specimen in the Herbarium Dumortier named U. viscosa Audibert was later sunk by Melville as U. × hollandica.
