Abstract

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.
