OriginEngland

The American elm cultivar Ulmus americana 'Incisa' was first described by Loudon in 1838 from a specimen in the Horticultural Society's Garden. [1]

Contents

Description

The tree had "leaves somewhat more deeply serrated and rather smaller" than the type, Loudon likening them to those of Ulmus effusa. [1] [2] [3]

Cultivation

The specimen in the Horticultural Society's Garden was 27 ft tall in 1834; Loudon considered it striking enough for a plate (Arboretum et fruticetum britannicum; Vol.II). [1] No specimens are known to survive, though forms with deeply serrated leaves sometimes occur in the wild. [3]
