摘要：

研究了国产毛茛属Ranunculus L.11种及其4个近缘属——美花草属Callianthemum C．A．Meyer、

侧金盏花属Adonis L．、碱毛茛属Halerpestes E．Greene、水毛茛属Batrachium S．F．Gray 5种植物的染色体

数目和形态。发现美花草C.pimpinelloides(D．Don)Hook．f.et Thoms.、川滇毛茛R．potaninii Kom．、深

齿毛茛R．popovii var．stracheyanus(Maxim．)W．T. Wang、高原毛茛R．tanguticus(Maxim．)Ovcz．、石龙

芮R．sceleratus L．、西南毛茛R．ficariifolius Lévl．et Vant．、褐鞘毛茛R．sinovaginatus W．T. Wang、三裂碱毛茛H．tricuspis(Maxim．)Hand．-Mazz．和碱毛茛H．sarmentosa (Adams) Kom．9种植物为染色体基数x

＝8的四倍体(2n=4x＝32)；短柱侧金盏花A．brevistyla Franch．、丝叶毛茛R．nematolobus Hand.-Mazz．、

棱喙毛茛R．trigonus Hand．-Mazz．、茴茴蒜R．chinensis Bunge 4种植物为染色体基数x＝8的二倍体(2n＝

2x＝16)；毛茛B．japonicus Thunb．、黄毛茛R．laetus Wall．2种植物为染色体基数x=7的二倍体(2n＝2x

＝14)；水毛茛R．bungei (Steud．) L. Liou 有二倍体(2n＝2x=16)和三倍体(2n＝3x=24)两种细胞型。根

据染色体资料，讨论了上述5属的属间关系和毛茛属中一些种的种间关系。

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.
