It is a slow-growing plant which loses its leaves during the dry season, and develops a swollen caudiciform trunk as it matures.

It has been found near ‘La Table’ hill approximately 25 km east of Toliara, along the escarpment edge of the adjacent Mahafaly Plateau, and in an area south of Onilahy River.

[1] It inhabits spiny thicket and coastal bushland with succulent species of Euphorbia on limestone rock, from sea level up to 160 meters elevation.

It is being degraded by livestock grazing, firewood collecting, charcoal production, selective logging, and agricultural expansion.

The species' main population is close to Toliara, a large and expanding town, which increases human impact on the landscape, including road-building and widening.
