The present paper reports the number of chromosome and karyotype of two species and two variety of lilium from Anhui.The origin of the material used in this work is provided in Table 1,micrographs of mitotic metaphase in plate 1,2,and the pa- rameters of chromosomes in Table 2,and the karyotype comparison in Table 3.The re- sults are shown as follows:1.Lilium brownii F. E. Brown Two material in this species were examined.One from Shexian. Anhui is fourd to have 2 cytotypes 2n=26 and 2n=24+1 Bs. Cytatype I: 2n=26= 1m+2sm+10st+ 10t+3T; Cytotype Ⅱ:2n=24+2Bs=2m+2sm+8st(2sc)+12t+2Bs. The other from Smtai,Anhui,is found to have 2n=24+1Bs=3m+1sm+6st+12t+2T+1Bs. 2.Lilium brownii F. E. Brown var. viridulum Baker Collected from Huoshan,Anhui,it has the karyotype formula 2n = 24+1bs =4m(2sc)+14st(2sc)+6t+1Bs. 3.Lilium speciosum Thunb.var. gloriosoides Baker Collected from Langyshan,Anhui,it is of karyotype formula 2n=24=4m+9st(2sc)+19t+1T. 4.Lilium callosum Sieb. et Zucc. Collected from Langyshan,Anhui,it is of karyotype formula 2n=24=2m+2sm+4st(2sc)+16t. Their karyotypes belong to Stebbins"3B".
