对金爪粉背蕨Aleuritopteris veitchii(Christ)Ching、硫磺粉背蕨A.duclouxii var.sutphurea Ching和A.cremea Ching ex S.K.Wu的模式标本进行了考证.根据原始描述指定了金爪粉背蕨的后选模式,并将A.cremea处理为它的异名.该种的特征是根状茎上的鳞片为同色,狭披针形,叶片分裂较细且被硫磺色粉状物.硫磺粉背蕨A.duclouxii var.sulphurea根状茎上的鳞片明显二色,与上者不同,本文重新恢复了该变种名称.

The type specimens of Aleuritopteris veitchii(Christ)Ching,A.duclouxii(Christ)Ching vat.sulphurea Ching,and A.cremea Ching ex S.K.Wu were carefully examined.The lectotype of A.veitchii was designated based on the original description.A.cremea was identical to the above species and thus reduced to a synonym of it.It is characterized by concolorous,linear-lanceolate rhizome scales and finely dissected fronds with sulphur-yellow farina.A.duclouxii var.sulphurea,whose rhizome scales are distinctly bicolorous,can be easily distinguished from A.veitchii.The name of the above variety is reinstated.
