Ulmus prunifolia W. C. Cheng & L. K. Fu, the Cherry-leafed Elm, is a deciduous tree endemic only to the province of Hubei in central eastern China, where it is found at elevations of 1000–1500 m.
Description
The tree can reach < 30 m in height, its bark dark grey and distinctively smooth. The narrow leaves vary in shape from elliptic to lanceolate, < 14 cm in length, and borne on twigs devoid of corky wings or layers. The wind-pollinated apetalous flowers are produced on second-year shoots from February; the samarae are oblong - obovate < 20 × 13 mm, and ripen in April - May.[1]
Pests and diseases
U. prunifolia was found to be among the least suitable elms for feeding and reproduction by the adult elm leaf beetle Xanthogaleruca luteola [2] [2] [3] and feeding by the Japanese Beetle Popillia japonica [3] [4] in the United States.
Cultivation
U. prunifolia is extremely rare in cultivation; all four trees grown at the Brenton Arboretum, Dallas Center, Iowa, died for reasons unknown circa 2006, but several specimens survive elsewhere in the USA, and one in Europe (see Accessions). U. prunifolia has never been in commerce.
