Two genera of the Umbelliferae, Tordyliopsis and Keraymonia, previously not known from China, have been revealed on the basis of original collections made by German-Chinese expeditions to Xizang (Tibet) Autonomous Region and adjacent areas. Tordyliopsis brunonis, gathered on the Tibetan side of the Mt Everest massif, was known only from India and Nepal. The mature fruit of Tordylopsis is described from Nepalese material. Keraymonia cortiformis, found in the Tibetan part of Mt Xixabangma, belongs to a genus with its previously known distribution limited to the Nepalese Himalaya. Findings of two additional species from other genera, Chamaesium mallaeanum, from Xizang (Xixabangma), and Aulacospermum stylosum from Xinjiang (Karakorum, K2 North slope), are also new to the Chinese flora.
