- On the Sino-American Botanical Expedition during the fall of 1980 seeds, thought to represent Sorbus zahlbruckneri, were collected. But a few years later it was determined that the plants derived from these seeds were a new species, subsequently named Sorbus yunan [J. Arnold Arboretum 67:265- 270(1986)].
- yunan: to honor Professor T. T. Yü, the leading Chinese plant taxonomist and student of the genus Sorbus.
