Taraxacum qirae, a species described from the Kunlun Shan, is clearly a member of T. sect. Borealia. Its closest relative, T. pavlovii Orazova, growing in C Tian Shan of Kazakhstan, differs in having substantially more numerous outer phyllaries and totally different achenes. The geographically closest member of this section, T. karakoricum Soest, lacks the whitish borders to the outer phyllaries and has a different leaf shape. The latter species might be found in China as it was described from the Karakoram of Pakistan, not far from the Chinese border.
