In FRPS, a broad species concept was adopted, with Allium tulipifolium and A. roborowskianum treated as synonyms of A. decipiens Fischer ex Schultes & J. H. Schultes, under which name all specimens in Chinese herbaria are filed. In the present account, a narrow species concept is adopted, with A. tulipifolium and A. roborowskianum treated separately from A. decipiens which was described from Ukraine and does not occur in China.
