Distribution of cytotypic variation in C. allisia section Cuthbertia. Diploid C. graminea (red circles) ranges from Virginia to North and South Carolina; tetraploid C. graminea (purple circles) occurs along the coastal plain from North Carolina to central Florida; hexaploid C. graminea (black plus signs) is restricted to central Florida. Diploid C. ornata (red squares) occurs in eastern and central Florida; tetraploid C. ornata (purple squares) is restricted to central and western peninsular Florida; hexaploid C. ornata (green plus signs) is restricted to central Florida. Callisia rosea (all diploid; green diamonds) occurs along the Georgia – South Carolina border. Localities with multiple cytotypes or taxa are indicated by black lines. Note: The black plus signs are the hexaploids of C. graminea, and the green plus signs are hexaploids of C. ornata
