Abstract: Homocodon brevipes, a species of the family Campanulaceae and endemic to China was karyo-morphologically studied for the first time . Its chromosome number is 68 and its karyotype is formulated as 2n = 68 = 56m+ 10sm+ 2st . By comparing with other cytological data of Campanulaceae , this species is probably tetraploid and the genus Homocodon maybe close to Campanula and Adenophora in phylogeny .

Key words: Homocodon brevipes
