Cephalocereus euphorbioides is a species of Cephalocereus from Mexico.

Description

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. The 7 to 9 straight, light gray marginal spines have a darker tip and are 5 to 12 millimeters long.

The narrow, bell-shaped flowers usually appear in large numbers near the tips of the shoots. They are reddish pink, 5 to 8 centimeters long and reach 7 centimeters in diameter. Its pericarpel and floral tube are covered with small tubercles with nectar glands and small scales. The green fruits are up to 8 centimeters long.[2]

Distribution

Cephalocereus euphorbioides is distributed in the Mexican states of Tamaulipas, San Luis Potosí and Veracruz.

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]
