The chromosomes of F. cymosum and F. giganteum. a and d are the metaphase of chromosomes of F. cymosum and F. giganteum in the mitotic cell of root tips, respectively. b and e are the karyotypes of chromosomes of F. cymosum and F. giganteum, respectively. There is obviously one larger (No. 1–8) and one smaller (No. 9–16) genome. c and f are the chromosomes of F. cymosum and F. giganteum in the meiosis MI of pollen mother cells, respectively. There are eight larger (marked with arrows) and eight smaller bivalents.
