dc.description.abstractKaryotype studies in eight species of Dalechampia, including 10 natural populations, revealed chromosome numbers (2n = 36, 46, 138 and 198) differing from two numbers cited in the literature (2n = 44 and 72). The basic number x = 6, as in the genus Acalypha, may be considered ancestral in Dalechampia. Analysis of Chromosome number, haploid chromosome length and karyotype symmetry suggests that the major chromosome mechanism acting in karyotype evolution of Dalechampia is polyploidy, but differences in chromosome morphology may be caused by chromosome rearrangements.
