These plants come from material originally collected at Farm Stegmann northwest of Willowmore, Western Cape Province of South Africa. E. horrida is a relatively large, squat cylindrical species characterized by a blue-green color, numerous ribs, and stout purple spines along the ribs. Variety major is simply a larger form of the typical species. The cyathia are dark purple. These plants are seedlings in one-gallon pots.
