Hybrids
? Ulmus x viminalis Lodd. ex Loudon (= Ulmus minor x Ulmus plotii) occurs in East Anglia and Central England with the parents and is planted elsewhere. The influence of Ulmus plotii is most often shown by the elongating short-shoots.
Ulmus procera x Ulmus plotii is rarely and perhaps doubtfully recorded from within the range of Ulmus plotii, and very sporadically elsewhere (e.g. North Wales) presumably planted.
? Ulmus x elegantissima Horw. (= Ulmus glabra x Ulmus plotii) is common within the range of Ulmus plotii. It can be told from Ulmus glabra x Ulmus minor by the erect habit often with pendent branches and the small leaves with blunt serrations. |
