This member of the Cactaceae family was first described by Leon in 1934. It is from Cuba, where it grows in grit on the hill-sides. It gets lots of water in two months and lots of sun all year. It will grow to 10 centimetres in diameter and 10 centimetres high. The flowers are pink/yellow, and seeds are the only way of reproducing.

A lot of photos from the wild: Bonaire.
