This species is characterized by 1-flowered cymules and by leaves with narrow segments. Some specimens occasionally have 2-flowered cymules， although most of the inflorescences have 1-flowered cymules. Some authors have suggested that European plants are characterized by pink to pinkish violet petals and villous vegetative parts and Siberian plants by white to pale pink petals and short and appressed trichomes. In Chinese specimens， these characters appear mixed in different combinations， which does not support such a division. Note also the discussion under Geranium nepalense.
