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。

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) + 8sm2) C. capitulata 2n= 2x= 18 = 10m(2SAT) + 8sm3) 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.
