The name Leontopodium junpeianum never appeared in other literature after its publication. When Kitamura published this name in 1935, he cited "Leontopodium linearifolium Handel-Mazzetti in Beih. Bot. Centrb. XLIV (1928) p. 100 non Bentham & J. D. Hooker (1873), pro parte ?" and noted the only difference with L. linearifolium Handel-Mazzetti is its cauline leaves with ± narrow base. When Y. Ling (Acta Phytotax. Sin. 10: 177. 1965) published the name L. longifolium, he similarly cited "Leontopodium linearifolium Handel-Mazzetti, Acta Horti Gothob. 1: 115. 1924, non (Wedd.) Bentham & Hook. f. (1873)." Obviously these two names represent the same species, so we use the older name here.
