The approximately 3 marginal spines are spread out and are up to 2.5 centimeters long.
The flowers are 4 centimeters to 7.5 centimeters long in diameter. The pear-shaped fruits are yellowish white and tinged with purple.

Taxonomy.
The first description as "Cereus crassisepalus" was made in 1973 by Albert Frederik Hendrik Buining and Arnold J. Brederoo. The specific epithet crassisepalus is derived from the Latin words crassus for 'thick' and sepalum for 'sepal' and refers to the thick-fleshed outer perianth segments. Nigel Paul Taylor and Daniela Cristina Zappi (* 1965) placed the species in the genus "Cipocereus" in 1991. Further nomenclature synonyms are "Piptanthocereus crassisepalus" (Buining &amp; Brederoo) F.Ritter (1979) and "Pilosocereus crassisepalus" (Buining &amp; Brederoo) Anceschi &amp; Magli (2010).
