Abstract:

The name Ranunculus gelidus is commonly used in North American literature for a widespread arctic-montane buttercup, but some recent American references have called this species R. karelinii , while Asian references use the names R. gelidus and R. karelinii for an endemic species of Central Asia, and use the name R. grayi for the plant of Eastern Siberia and Western North America. Ranunculus gelidus is the correct name for a narrow endemic in the Tian Shan and Jungar Shan of Central Asia, and R. karelinii is illegitimate (a superfluous replacement for R. gelidus). Populations from Eastern Siberia and North America, which differ from R. gelidus in their straight (not inflexed) achene beak, smaller petals, and less deeply divided leaves, are correctly known as R. grayi. The section in which this species is placed is correctly called Ranunculus sect. Epirotes (Prantl) Benson—"Ranunculus sect. Auricomus Spach," used in some recent publications, is not valid.
