报道了中国产光萼苔科四种植物配子体有丝分裂中期的染色体数目和核型,四种植物的染色体数目均为n=8.核型为:细光萼苔陕西变种(P.gracillima var.urogea)k(n)=8=8m或k(n)=8=4v+4(v);毛缘光萼苔(P.vernicosa)k(n)=8=5m+3sm或k(n)=8=6v+2J;密叶光萼苔(P.densifolia)k(n)=8=8m或k(n)=8=5v+3(v);多瓣苔(Macvicaria ulophyl-la)k(n)=8=6m+2sm或k(n)=8=6v+1(v)+1J.

Chromosome numbers and karyotypes of four species of Porellaceae from China are reported. Chromosome of mitotic metaphase of growth tips of stems of gametophytes were observed. Three species of the genus Porella showed the same chromosome number of n = 8, identical to the previous reports. Macvicaria ulophylla (n = 8 ), different chromosome numbers from previous counts are obtained. P. gracillima var. urogea has the karyotype of k(n) =8 =8m or k(n) =8 =4v +4(v); P.vernicosa has the karyotype of k(n) =8 =5m +3sm or k(n) =8 =6v +2J; P. densifolia has the kar-yotype of k (n) = 8 = 8 m or k (n) = 8 = 5 v + 3 (v); Macvicaria ulophylla has the karyotype of k (n) =8 =6m +2sm or k(n) =8 =6v + 1(v) + 1J.
