Ulmus villosa, the cherry-bark elm or Marn elm, is one of the more distinctive Asiatic elms, and a species capable of remarkable longevity. It is endemic to the valleys of the Kashmir at altitudes of 1,200–2,500 metres but has become increasingly rare owing to its popularity as cattle fodder. Mature trees are now largely restricted to temples and shrines where they are treated as sacred. Some of these trees are believed to be over 800 years old.
The hybrid elm cultivar Ulmus × hollandica 'Wredei', also known as Ulmus × hollandica 'Dampieri Aurea' and sometimes marketed as Golden Elm, originated as a sport of the cultivar 'Dampieri' at the Alt-Geltow Arboretum, near Potsdam, Germany, in 1875.

The Wych Elm cultivar Ulmus glabra 'Horizontalis', commonly known as the Weeping Wych Elm or Horizontal Elm, was discovered in a Perth nursery circa 1816. The tree was originally identified as 'Pendula' by Loddiges (London), in his catalogue of 1836, a name adopted by Loudon two years later in Arboretum et Fruticetum Britannicum, 3: 1398, 1838, but later sunk as a synonym for 'Horizontalis'.
Ulmus 'Louis van Houtte' is believed to have been first cultivated in Ghent, Belgium circa 1863. It was first mentioned by Franz Deegen in 1886. It was once thought a cultivar of English Elm Ulmus minor 'Atinia', though this derivation has long been questioned; W. J. Bean called it "an elm of uncertain status". Its dissimilarity from the type and its Belgian provenance make the 'Atinia' attribution unlikely. Fontaine (1968) considered it probably a form of U. × hollandica.
Tilia × europaea, generally known as the European lime, common lime or common linden, is a naturally occurring hybrid between Tilia cordata and Tilia platyphyllos.
