Echidnopsis cereiformis is a small snake-like succulent with thin tufted cylindrical branches (as implied in its generic name which means “viper-like”). It is named “cereiformis” from its cactus-like appearance (also a good mimic of stems of Euphorbia mamillaris). Tiny lovely flowers sprout out of the entire length of each stem but mainly toward the tip in autumn, they are typically pale to dull yellow, but also brownish or dark brown-purple.
