Euphorbia horrida is a spiny succulent shrub with irregular basally clumping stems. In age it will forms tight clumps of upright columns up to a meter wide that closely resemble some cactus species. It also has clustered crowns of somewhat ferocious spines much like the true cacti.
Remarks: This plant is somewhat variable with many varieties and forms, and perhaps natural hybrids between it and taller Euphorbias.
