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 may be close to Campanula and Adenophora in phylogeny.
