| Origin | Europe |
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 Arb. Frut. Brit. 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.[1]
Description
'Viscosa' was distinguished by its large, deep-green leaves with anthocyanin pigment.[2]
Cultivation
Probably extinct in Europe.
