The one or two light to dark brown central spines are directed downwards and are up to 5 cm (2.0 in) long. The up to 30 and more needle-like yellowish radial spines have a length of 5 to 8 mm (0.20 to 0.31 in).
The white flowers reach a diameter of 4.5 cm (1.8 in) and a length of up to 8 cm (3.1 in).[3]

[edit]The first description as Cereus decumbens was made in 1913 by Friedrich Karl Johann Vaupel.[4] Curt Backeberg placed the species in the genus Haageocereus in 1934. Other nomenclature synonyms are Borzicactus decumbens (Vaupel) Britton & Rose (1920), Binghamia decumbens (Vaupel) Werderm.
