Abstract: The type specimens of Aleuritopteris veitchii (Christ) Ching, A. duclouxii (Christ) Ching var. 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.

Key words: Aleuritopteris, lectotype, new synonymy, Aleuritopteris veitchii, Aleuritopteris duclouxii var. sulphurea
