摘　　要：报道了秃疮花属3种,即苣叶秃疮花、秃疮花和宽果秃疮花共11个居群及其姐妹类群海罂粟属1种(海罂粟)一个居群的染色体数目。研究结果表明,秃疮花属全部三种的染色体数目均为2n=12;海罂粟的染色体数目为2n=10,并且是该属中新发现的最小数目。The cytological studies were performed in 11 populations of Dicranostigma lactucoides, D. leptopodum, and D. erectum and one population for Galuciumfimbrilligerum. All three species of Dicranostigma possessed chromo- some number 2n = 2x = 12, of which chromosome numbers for D. erectum and D. lactucoides are reported here for the first time. Glauciumfimbrilligerum presented the number 2n= 2x= 10, which is not only new to the genus but also the known lowest number for Glaucium.
