| Ulmus pseudopropinqua Wang & Li |
Ulmus pseudopropinqua Wang & Li is a small deciduous tree found only in the northeasternmost province of Heilongjiang in China, where it grows to a height of 10 m. Its wing-less twigs bear small ovate to subovate leaves, < 5.5 cm long by 2.5 cm broad. The wind-pollinated petal-less flowers are produced on second-year shoots in April; the variably-shaped samarae < 25 mm long by 20 mm wide ripen in June.
The tree is one of a range of rare Chinese elms currently under evaluation as landscape plants at the Morton Arboretum, Illinois. It has already been found to be unaffected by elm leaf beetles.
