The Identity of Anemone jiachaensis (Ranunculaceae)

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.
