Melocactus estevesii

A small Turk's-cap cactus from Roraima in far northern Brazil, known from very few wild records on granite outcrops in savanna country. Like other lowland tropical melocacti it needs constant warmth, strong sun and a very fast-draining mineral mix, and it should never be chilled.

Where it grows wild

Inferred from the genus and region: crevices and shallow gravel pockets on exposed granite or gneiss outcrops rising from savanna.

Only one record; the climate site was placed at about 550 m, while the surrounding savanna lies near 100 to 200 m. Treat elevation as uncertain.
