Cephalocereus euphorbioides grows with rarely branching green shoots 3 to 5 meters tall and 10 to 11 centimeters in diameter. The 8 to 10 noticeable ribs are clearly wavy. The thorns are only upright in the flower zone and are otherwise more or less horizontal. The single, strong central spine is dark brown and up to 3 centimeters long.

Taxonomy
The first description as Cereus euphorbioides was in 1819 by Adrian Hardy Haworth.[3] The specific epithet euphorbioides is derived from the Greek word -oides for 'similar' and the genus 'Euphorbia'. Nathaniel Lord Britton and Joseph Nelson Rose placed the species in the genus Cephalocereus in 1920. Further nomenclature synonyms are Cactus euphorbioides (Haw.) Spreng. (1825), Pilocereus euphorbioides (Haw.) Rümpler (1886), Lemaireocereus euphorbioides (Haw.) Werderm. (1934), Carnegiea euphorbioides (Haw.) Backeb. (1944), Neobuxbaumia euphorbioides (Haw.) Buxb. (1954), Neodawsonia euphorbioides (Haw.) Buxb. (1957) and Rooksbya euphorbioides (Haw.) Backeb. (1960).[4]
