This member of the Cactaceae family was
first described by Jesús González Ortega in 1927. It is from Mexico, 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 30 centimetres in diameter and
two meters high. The flowers are red/yellow, and seeds are the only
way of reproducing. I found Rikke's in Amsterdam 2001.
