Buddleja alata is endemic to western Szechuan, China, growing at elevations of 1,300–3,000 m; it was first described and named by Rehder and Wilson in 1913. Leeuwenberg found the plant to be such a perfect intermediate of "Buddleja albiflora" and "Buddleja nivea" as to consider it a hybrid of the two species. Using only the above description and what you know about the world, "Buddleja alata is typically found in western Szechuan, China at elevations as high as 3,100 m." is definitely correct, incorrect, or inconclusive?
