 The cut-leaved American Elm (Loudon) | |
| Species | Ulmus americana |
| Cultivar | 'Incisa' |
| Origin | England |
The American Elm cultivar Ulmus americana 'Incisa' was first described by Loudon in 1838 from a specimen in the Horticultural Society's Garden.[1]
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]
