Generally considered a synonym of Abies forrestii forrestii (Zhang et al., 2013; Earle, 2023; POWO, 2023):

"Abies chengii was an interesting case, having been described solely on the basis of material collected in arboreta in England, Scotland and Ireland, derived from seed collected in Yunnan by George Forrest in 1931 (Farjon 1990), and Farjon (2010) concludes that "it is more probably another variety (or a mere form not deserving a botanical name) of A. forrestii." No comparable trees have since been reported in habitat."

(Earle, 2023)
