From Wikipedia, the free encyclopedia
The Ulmus × hollandica cultivar 'Modiolina' was first described by Dumont de Courset [2] in Bot. Cult. 3: 700, 1802, as U. campestris var. modiolina, "l'orme Tortillard". It was described as a pyramidal form of medium height with small leaves and crowded branches, and by later authors as having twisted and crowded branches with gnarled stems. A tree grown at Kew was identified by Melville as U. × hollandica [1]. 'Modiolina' is not known to remain in cultivation. A specimen at the Ryston Hall [3], Norfolk, arboretum, obtained from the Späth nursery in Berlin before 1914 [2], was killed by the earlier strain of Dutch elm disease in the 1930s.
