  • Echinofossulocactus crispatus f. kellerianus
  • Stenocactus kellerianus


-It is native of north and central Mexico.


-Echinofossulocactus kellerianus is one of the most widespread forms of the E. crispatus. It is an usually solitary round or flat cactus, its stem is very wooly, that grows up to 4 cm high and 7 cm of diameter. It has 60 ribs, hard and wavy: their matt dark-green color contrasts with the yung, white areoles. Spines are strong, up to 3 cm long, usually light brown. Flowers are white with violet centre strip.


-E. kellerianus needs a regular cacti soil with little organic matter. It requires very good drainage and air circulation. Repot every other year. Rot sensitive: water adequately during summer, when soil should always be moist. Don’t water in winter. Sensitive to frost. It prefers bright light outside and some direct sunlight inside, but it is subject to sunburn when exposed for too long. In strong light it tends to bronze: that also encourages flowering and spine production.


-Propagate by seeds or if available, by shots.


-Echinofossulocactus are commonly called Brain plants due to their wavy ribs.
