Abstract: Fifteen species in six genera of the family Liliaceae were karyomorphologically studied. They share the complex chromocenter type of the resting nuclei and the interstitial type of the prophase chromosomes in somatic cells except that Clintonia udensis Trautv. et Mey is of the densely diffuse type and gradient type respectively. Their karyotype formulas are listed as follows: Clintonia udensis Trautv. et Mey, 2n= 14=8m+4sm+2st (2SAT), belongs to 2A type; Smilacina henryi (Baker) Wang et Tang, 2n=36=12m+16sm+6st+2t (2SAT), 2C type; Smilacina fusca Wall., 2n = 36= 14m (2SAT) + 12sm+ 10st(2SAT), 2B type; Smilacinata tsienensis (Franch.) Wang et Tang, 2n= 36=22m +2sm+ 2st(2SAT), 2C type; Smilacina atropurpurea ( Franch.) Wang et Tang, 2n=36=18m+6sm(2SAT) +12st, 2C type: Polygonatum kingianum Coll, et Hesml., 2n=30= 12m(2SAT) +6sm+ lst+2t, 2C type; Polygonatum cirrhifolium (Wall.) Royal, 2n=30= 10m+4sm+ 12st+4t, 3C type; Polygonatum curvistylum Hua, 2n=78=24m (2SAT)+ 14sm (6SAT)+40st, 3C type; Polygonatum cathcartii Baker, 2n = 32 = 12m + 6sm + 10st+ 2t + 2Bs, 2C type; Lilium henricii Franch., 2n = 24 = 2m(2SAT) + 2sm + 10st+ 10t, 3A type; Lilium bakerianum Coll. et Hesml. var. rubrum Stearn, 2n=24=4m ( 2SAT) +10st+ 10t (2SAT), 3A type; Nomocharis bilouensis Liang, 2n= 24= 2m (2SAT) +2sm+ 12st+ 8t, 3A type; Nomocharis pardanthina Franch., 2n= 24=4m (2SAT)+12st (2SAT)+ 8t, 3A type; Nomocharis sauluensis Balf. f., 2n=24=4m(2SAT) +10st (2SAT) + 10t, 3B type; Notholirion campanulatum Cotton et Stearn 2n = 24 = 2m (2SAT) + 2sm + 14st(2SAT ) + 6t, 3A type.
