Pilosocereus diersianus

A critically endangered columnar cactus up to about 2 m tall, with bluish stems and long bluish-white wool. Only around 50 plants are thought to remain in the wild, on rocky outcrops in the cerrado of Goiás and Tocantins. It wants full sun, heat, and a strict dry winter followed by a wet summer.

Where it grows wild

Rocky outcrops in the cerrado and dry forest of central Brazil. This is generalised from the genus, because habitat detail for this species is thin.

Probably around 450–750 m. Few records carry an elevation.
