Justification | This species has an extent of occurrence (EOO) of 400 km² and has lost over 80% of its habitat over the past 25 years (generation length 20 years) to crop cultivation.

Presently, it is known from only two fragmented subpopulations and from 61 plants, 60 of which occur in one subpopulation. |
