摘要	A karyomorphological analysis on four species of Meconopsis (Papaveraceae) from the Hengduan Mountains, SW China was carried out for the first time. First chromosome counts are notified in two species: M. racemosa Maxim (2n=56=6m+20sm+30st) and M. pseudovenusta Tayl. (2n=56=4m+36sm+16st). Furthermore, the somatic chromosome number of M. horridula Hook.f.et Thorns. (2n=56=4m+16sm+36st) is also confirmed. For M. integrifolia (Maxim.) Franch is presented an unreported chromosome number (2n=76=6m [2 sat] +26sm+44st). The karyotypes of all analyzed species belong to 3B type according to Stebbins' asymmetry classification. The most common chromosome base number of x=7 is thought to be tentative with another possibility of x=14.; A karyomorphological analysis on four species of Meconopsis (Papaveraceae) from the Hengduan Mountains, SW China was carried out for the first time.
