The elm cultivar Ulmus 'Planeroides' [:Planera-like elm] was described by Carrière in the Revue horticole, 1875.[1] It was considered "possibly Ulmus carpinifolia" [:U. minor ] by Green.[2]
Not to be confused with Späth's U. montana viminalis which, though "also distributed under the name Planera aquatica",[3] has osier-like leaves, Planera being the old name for Zelkova, a close relative of elm with willow-like leaves.[4]

Pests and diseases
Most field elm clones are susceptible to Dutch elm disease.
Cultivation
