Ulmus glabra 'Australis' is a Wych Elm cultivar described by Loudon in 1838, from a tree in the Royal Horticultural Society garden, as U. montana var. australis Hort.. Loudon's 'Australis' is not to be confused with Henry's U. campestris 'Australis', a tall southern European field elm or hybrid cultivar with an oval leaf and longer petiole.
