The same constraints apply to subdivisions of lower ranks. For example, Veronica hybrida L. was deemed by E. F. Warburg to be a component of Veronica spicata L. and he named
it V. spicata L. subsp. hybrida (L.) E. F. Warburg. This implies the existence of a typical subspecies, the autonym for which is V. spicata L. subsp. spicata.
