The fruit does not break into four mericarps, but splits into two two-seeded carpids. Exo- and mesocarp wither after fruit-ripening and the endocarp constitutes the remaining outer wall. Within the stony endocarp tubular parenchymatic isles develop which are linked with the mesocarp. Subsequent disintegration pretends additional locules in the mature fruit. Similar pericarp formations are also found in someHeliotropium species but result from a different ontogeny. Therefore, although a close relationship ofCeballosia toHeliotropium is obvious, the taxon should be treated as a separate genus.},

Each main clade identified in the molecular studies is well characterized on the basis of leaf anatomy.},
