摘要
In this study, 9 new combinations, 6 at species level and 3 at varietal level in the tribe Cichoreae have been proposed from Pakistan and Kashmir. Of these, seven taxa, previously placed in Cicerbita Wallr. and one species of Prenanthes L. are now transferred in the genera viz., Melanoseris Decne and Lactuca L. A new combination, Crepidiastrum afghanicum (Podlech) A. Ghafoor & Qaiser comb. nov., is also proposed. This taxon is a new record for Pakistan. In order to validate the new combinations and records, basionym, complete reference and a key to differentiate all the four genera viz., Lactuca, Cicerbita, Melanoseris and Perenenthes is also given.
