Taxonomic notes: Russian Far East flora (Koropachinskiy and Vstovskaya, 2002) treats L. monanta Nakai as correct name and L. subhispida Nakai as synonym, but due to equal priority issue and Chinese flora's prior treatment of L. monantha as synonym of L. subhispida Nakai, the latter should be used as the correct name.
