-It is native of the mexican States of Hidalgo, Queretaro and Veracruz.
-Echinofossulocactus lamellosus is a geographical form of the Echinocactus crispatus. The stem is cylidrical or globose and its apex is depressed. This plant has thin, flat ribs (25-35), with very wavy ridges. Central spine is flat and very long (from 1 to 8 cm long) and directed upwards while the 5-6 radial ones are shorter (1 cm long). Flowers are white with violet centre strip.
-E. lamellosus requires a regular cacti soil with little organic matter. It needs very good drainage and good 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.
