- The paper presents chromosome counts and karyotypes for two species of Chrysolaena, revealing both taxa have a basic chromosome number (x=10) common to the genus.
- The study reports the first chromosome count for Chrysolaena cristobaliana, identifying it as heptaploid (2n=7x=70) and detailing its karyotype, while also providing information on the tetraploid (2n=4x=40) karyotype of Chrysolaena sceptrum.
- Both species exhibit accessory chromosomes and differ in chromosome number and total length, but share similarities in morphology and asymmetry indexes, suggesting that chromosome data can be useful for classifying members of the Vernonie
