Where it grows wild

Recorded along the arid southern coastal strip of eastern Cuba (Guantánamo and Santiago area), the island's driest region; like other Caribbean Melocactus it grows among low thorn scrub on rocky, mostly limestone coastal ground.

Measured records sit at 17–177 m, median 45 m: a near-coastal lowland plant.
