| الوصف: | Somatic chromosome numbers and karyological features in 22 taxa of the genus Canna (Cannaceae) were investigated and are presented here for the first time. The chromosome numbers were primarily reported for C. bangii, C. indica var. sanctae-rosae and C. tulianensis. A triploid somatic chromosome number of 2n = 27 was found only in C. discolor, while the remaining taxa were diploids with 2n = 18. Chromosome numbers are considered to be remarkably stable within the Cannaceae. Canna shows a symmetric karyotype that consists mostly of median chromosomes, but with some subterminal or submedian chromosomes, and a karyotype homogenous in variation in chromosome length. The karyotype of some taxa of Canna, furthermore, is characterized by median chromosomes with a secondary constriction in the centromeric region. Cytotaxonomical characteristics of the family Cannaceae and the related groups in the Zingiberales are discussed. |
