Preliminary conservation status assessment.

This species has an Extent of Occurrence ( EOO) of 295,960.413 km 2 and an Area of Occupancy ( AOO) of 176.000 km 2 and is assessed as Least Concern ( LC) following IUCN (2022).

Notes.

Strobilanthes dimorphotricha subsp. rex differs consistently from subsp. dimorphotricha Hance from China and Vietnam in the rigid and subequal or sometimes unequal leaves. Subsp. rex appears similar to S. paniculiformis J. R. I. Wood in which the calyx lobe has 1 lobe longer than others. However, it differs by having ovate or elliptic-lanceolate bracts vs. ovate-orbicular in S. paniculiformis .
