and the only permissible way of indicating that the taxon includes the type for the species name. 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.
