Abstract: The present paper reports the chromosome numbers and karyotypes of 5 species in Ranunculus from Jiangxi. The result is shown in Table 1-2. The chromosome numbers of R. ternatus Thunb. (2n=4x=32; 2n=2x=16=8m+2sm+6st) , R. polii Franch. (2n = 2x = 16 = 8m+2sm+6st) and R. sieboldii Miq. (2n = 8x-1 = 63 = 15m+18sm+22st+8t) are first reported. The essential points are as follows: (1) The karyotypes of R. ternatus Thunb. and R. polii Franch. are rather similar, which shows a close relationship between the two species. (2) Polyploid complexes are common in Ranunculus. (3) According to the taxonomical system of Wang Wen-cai, the karyotypes of the two species investigated in Sect. Auricomus belong to “2A” of Stebbins; that of the only species in Sect. Hecatonia belong to “2B'; the karyotypes of the two species investigated in Sect. Ranunculus belong to “3A” or “3B”. The relationships among t
