加查银莲花(毛茛科)的名实订正

The Identity of Anemone jiachaensis (Ranunculaceae)

摘要:

通过标本检查, 发现毛茛科加查银莲花(Anemone jiachaensis W. T. Wang)与西藏银莲花(A. tibetica W. T. Wang)属于同一种植物, 故将前者处理为后者的异名。加查银莲花发表时被置于鹅掌草组[A. sect. Stolonifera (Ulbr.) Juz.], 但其花粉为三沟而非多沟, 与岩生银莲花亚组[A. subsect. Rupicolae (Tamura ex Chaudhary & Trifonova) Starod.]的岩生银莲花(A. rupicola Camb.)(西藏银莲花亦属于该亚组)的花粉类型一致, 而与鹅掌草组植物的多沟花粉明显不同, 从而进一步表明加查银莲花与西藏银莲花确为同一种植物而且应为岩生银莲花亚组的成员。

Abstract:

Examination of herbarium specimens has shown that Anemone jiachaensis W. T. Wang (Ranunculaceae) is conspecific with A. tibetica W. T. Wang. We therefore reduce A. jiachaensis to the synonymy of A. tibetica. When A. jiachaensis was published, it was regarded as a member of A. sect. Stolonifera (Ulbr.) Juz. Its pollen grains, however, are not stephanocolpate (polycolpate), the pollen type that characterizes Anemone sect. Stolonifera, but are 3-colpate, the same type as that in A. subsect. Rupicolae (Tamura ex Chaudhary & Trifonova) Starod. This has further lent strong support for the synonymization of A. jiachaensis with A. tibetica, a member in A. subsect. Rupicolae.
