This species is highly variable. For example, the type of Polygonatum cavaleriei ( Cavalerie 2166, E) is apparently quite different from that of P. kingianum in leaves and flowers. Further studies are needed to confirm whether or not the synonyms listed above for P. kingianum really belong to this species.
