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.
Christ (1906) published Doryopteris veitchii Christ based on two different specimens.
One of them (Wilson 5397, Fig. 1: A), which is characterized by concolorous, linear-
lanceolate rhizome scales and finely dissected fronds with sulphur-yellow farina, is
designated here as the lectotype, based on the original description; the other (Wilson 5396,
Fig. 1: B), whose rhizome scales are lanceolate, bicolorous, with dark central stripe and light
narrow margins, should be referred to as another species (Aleuritopteris duclouxii (Christ)
Ching var. sulphurea Ching). Later, Ching (1941) transferred Doryopteris veitchii into the
genus Aleuritopteris Fée.
In 1935, Ching proposed a new variety, Cheilanthes duclouxii (Christ) Ching var.
sulphurea Ching, which differs from the typical variety (C. duclouxii) in its sulphur-yellow
farina. Moreover, he pointed out that this variety should not be confused with Cheilanthes
veitchii (Christ) Ching (Aleuritopteris veitchii), from which it differs in the stipe being not
glossy black and fronds not so finely dissected. Later, Cheilanthes duclouxii was moved to the
genus Aleuritopteris, and the above variety was still treated as distinct from A. veitchii (Ching,
1941). However, Wu (1981) treated it as a synonym of A. veitchii. At the same time, he
proposed a new species named Aleuritopteris cremea Ching ex S. K. Wu. After examining
specimens of the complex, including the type, we confirm that A. cremea is identical to A.
veitchii, and the former one should be reduced as a synonym. The erroneous taxonomic
treatment was also followed in “Flora Reipublicae Popularis Sinicae” (Wu, 1990). So the
specimens of the above two taxa deposited in Chinese herbaria are often erroneously labeled.

other, basal pair largest, nearly triangular, 1-pinnate-pinnatifid; pinnules 4–7 pairs, proximal

摘要 对金爪粉背蕨Aleuritopteris veitchii (Christ) Ching、硫磺粉背蕨A. duclouxii var. sulphurea 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。
