This hybrid combination is to be expected in limited numbers wherever the parental species are contiguous. Eight individuals of this hybrid combination had a mean pollen stainability of 70% and exhibited a maximum chromosome pairing configuration of 12II + 1M3 during meiosis. The formal designation Railliardia demissifolia var. verticillata Sherff has been applied to this hybrid combination.
