Abstract:

( 1 ) Nine species and 4 varieties are described as new, and 2 new ranks, 1 new combi-

nation, and 1 new name are proposed. (2) Clematis dioica L. ssp. virginiana (L.) Kuntze var.

bahamica Kuntze, C. bahamica (Kuntze) Britton, C. orbiculata Correll, C. brasiliana DC.

var. laxa St. Hilaire, C. perulata Kuntze, C. barrancae Jones, C. discolor Gardn., C. laxi-

flora Baker, C. bathiei Lévl., and C. mauritiana Lam. var. sulfurea Viguier & Perrier are re-

duced into synonymy. (3) A new classification for the varieties of C. chinensis Osbeck is prop-

osed. (4) The specific status of C. flukenetii DC. is discussed and confirmed. (5) The differences

between C. acapulcensis Hook. & Arn., the South American population of which has been misi-

dentified as C. affinis St. Hilaire, and its close ally, C. affinis St. Hilaire, are given. (6) The

taxonomical confusion made by Viguier and Perrier about the species belonging to sect. Meclatis

subsect. Wightianae distributed in Madagascar and adjoining islands is clarified, and an enumera-

tion of them with a key is given.
