Three genera (Zosima Hoffm., Lithosciadium Turcz., and Lomatocarpa Pimenov)
were shown for the first time for the Chinese flora on the basis of collections kept in Ürümqi [ Insti-
tute of Biology, Pedology and Desert Investigations (XJBI), CAS]. In the same herbarium, some
additional floristic novelties were found: two genera ( Pleurospermum s. str. and Kadenia ) and six
species new for Xinjiang. A new species, Dimorphosciadium shenii Pimenov et Kljujkov has been
described, being a Xinjiang endemic. Some corrections in taxonomy and nomenclature for local spe-
cies of Ferula, Seseli, Aphanopleura, Aegopodium, and Sium have been proposed. In total, 126
species and 53 genera of the Umbelliferae are registered for Xinjiang.
