A detailed morphologic study of the mitotic chromosomes of root tips in each of the currently recognized species of Silphium reveals a diploid complement of 14 chromosomes. The karyotypes of the species are similar and cannot be separated into distinct groups. Although there is variation among the species in both arms of the chromosomes, the short arm varies in length more than the long arm. Although the short arms of Chromosomes VI and VII are extremely short, there are no satellites. The chromosomes possess a distinct and recognizable morphology.
