Ranunculus wangianus Q. E. Yang, a new species from NW Yunnan, China and its karyotype
云南西北部毛茛属一新种——文采毛茛及其核型

Ranunculus wangianus Q. E. Yang is described as new. This species, a hexaploid with 2n = 6x = 48, is different from its closet ally, R. yunnanensis, a diploid with 2n = 2x = 16, in the characters of foliage. It is also somewhat similar to R. felixii Lévl., but the latter is a tetraploid with 2n = 4x = 32, usually with only one basal leaf and the roots are thickened from base andfleshy.
