Abstract
Clematis pseudotubulosa (Ranunculaceae), a new species from Gyeonggi-do in the Republic of Korea, is described and illustrated. The new species is morphologically similar to C. takedana but differs in its leaves, which are always ternate with shallowly lobed leaflets (vs. 1-pinnate with deeply lobed three to five leaflets), and its oblong-shaped flower buds (vs. ovoid), larger flowers (vs. smaller flowers), and pantoporate pollen (vs. tricolpate). A detailed species description, geographical distribution, and an identification key for all species of Clematis that occur in Korea are also provided.
Keywords: Clematis, interspecific hybridization, new species, Ranunculaceae
