First genome size assessments for Marshallia and Balduina (Asteraceae, Helenieae) reveal significant cytotype diversity

The genus Marshallia is made up by seven to ten species of perennial herbs growing mainly in open habitats, whereas the genus Balduina is represented by three sympatric species; two perennial herbs and one annual, growing in open pine forest habitats. Both genera belong to the family Asteraceae, tri...
