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. stracheya-
nus (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 of
some species within Ranunculus are discussed.
