Abstract: Abstract This paper deals with the karyotype analysis of 3 species of Curculigo from China. The karyotype formulae are as follows: 1 ) C. crassifolia 2n= 2x = 18 = 10m(4SAT) + 8sm 2) C. capitulata 2n= 2x= 18 = 10m(2SAT) + 8sm 3) C. sinensis 2n=2x=18= 8 m(3SAT) + 10sm(2SAT) Among them, the karyotype of C. sinensis S. C. Chen are reported for the first time. The karyotypes of 3 species of this genus fall into "2B" type, but the karyotype of C. sinensis might be more asymmetrical than C. crassifolia and C. capitulata based on their asymmetry indexes.

摘要： 本文报道了中国产三种仙茅植物的核型。1.绒叶仙茅Curculigo crassifolia(Baker)Hook. f.,2n＝2x=18＝10m(4SAT)＋8sm；2.大叶仙茅C．capitulata(Lour．) O．Kuntze，2n=2x=18＝10(2SAT)＋8sm；3.中华仙茅C．sinensis S.C. Chen, 2n＝2x＝18＝8m(3SAT)＋10sm(2SAT)。其中中华仙茅的核型为首次报道。虽然三种仙茅的核型都是“2B”型，但中华仙茅的核型不对称性比绒叶仙茅和大叶仙茅强。
