Strobilanthes involucratus Bl.Pachystrobilus involucratus (Blume) Bremek.Strobilanthes erosa Nees Strobilanthes involucrata[1] is a species of flowering plants in the family Acanthaceae and the tribe Ruellieae.

It is found in south-east Asia: native to Java and introduced to Indo-China.

This was previously considered a species of the monotypic genus Pachystrobilus.
