Abstract: The somatic chromosome number and detailed chromosome morphology have been studied in eleven species of Ranunculus and five species of its four related genera, all from China, namely Callianthemum pimpinelloides (D. Don) Hook. f. et Thoms. (2n = 4x= 32), Adonis brevistyla Franch. (2n = 2x = 16), Ranunculus potaninii Kom. (2n= 4x = 32), R. popovii var. stracheyanus (Maxim.) W. T. Wang (2n = 4x = 32), R. tanguticus (Maxim.) Ovcz. (2n = 4x = 32), R. nematolobus Hand.-Mazz. (2n = 2x = 16), R. sceleratus L. (2n = 4x = 32), R. ficariifolius Lévl. et Vant. (2n = 4x = 32), R. japonicus Thunb. (2n = 2x = 14), R. laetus Wall. (2n = 2x = 14), R . trigonus Hand.-Mazz.(2n = 2x = 16), R . sinovaginatus W . T . Wang (2n = 4x = 32), R. chinensis Bunge (2n = 2x = 16), Halerpestes tricuspis (Maxim.) Hand.-Mazz. (2n = 4x = 32), H. sarmentosa (Adams) Kom. (2n = 4x = 32) and Batrachium bungei (Steud.) L. Liou (2n = 2x = 16; 2n = 3x = 24). From the chromosomal data relationships of the five genera and ofsome species within Ranunculus are discussed.
