摘　　要：报道忍冬科 (Caprifoliaceae)荚迷属 (Viburnum) 2种植物的核型 ,臭荚迷 (V .foetidumWall.)为 2n =18,核型公式为 2n =2x =18=14m + 4sm ,核型属于“2B”型 ;水红木 (V .cylindriumBuch .-HamexD .Don)为2n =18,核型公式为 2n =2x =18=12m + 6sm ,核型亦属“2B”型 .这 2个种的染色体数目与文献报道一致 ,而其核型为首次报道 .Reports the karyotypes of 2 species from the genus of Viburnum,Caprifoliaceae.The karyotype of Viburnum foetidum Wall is 2n=2x=18=14?m+4?sm and belongs to the"2B"type;While Vibrunum cylindrium Buch.-Ham ex D.Don has the karyotype of 2n=2x=18=12?m+6?sm,and the "2B"type.The chromosome numbers of the 2 species are the same as those published,but their karyotypes are firstly reported in this paper.
