Where it grows wild

Not described in the sources opened; the name refers to Bemaraha, a limestone tsingy massif with dry deciduous forest, so a rocky limestone habitat is likely.

The single GBIF record is in the central highlands at about 1200 m; Bemaraha itself lies far lower, at roughly 100–700 m.
