Acanthocereus is a genus of cacti.Its species take the form of shrubs with arching or climbing stems up to several meters in height. The generic name is derived from the Greek word άκανθα (acantha), meaning spine, [3] and the Latin word cereus, meaning candle. [4]

The classification of the Cactaceae thus remains subject to change, from the genus level upwards. In 2016, David Hunt wrote that "the advent of molecular systematic studies in the past two decades will hopefully have a stabilizing effect on classification in due course, but has so far had the opposite effect".

Strophocactus brasiliensis was first described, as Acanthocereus brasiliensis, by Britton and Rose in 1920. [2] It was transferred to the genus Pseudoacanthocereus as Pseudoacanthocereus brasiliensis by Friedrich Ritter in 1979, [7] a placement still accepted by some sources as of February 2021. [3]
The 2011 study found the tribe Hylocereeae to be embedded within a wider Echinocereeae, but studies in 2017 and 2020 asserted the independence of the Hylocereeae, including within it two genera placed within Pachycereeae in earlier classifications: Acanthocereus and Pseudoacanthocereus (sunk into Strophocactus).

Acanthaceae (/ æ k æ n ˈ θ eɪ s iː ˌ aɪ,-s i ˌ i /) is a family (the acanthus family) of dicotyledonous flowering plants containing almost 250 genera and about 2500 species. Most are tropical herbs, shrubs, or twining vines; some are epiphytes.
Strophocactus wittii, which had been included in Selenicereus, was excluded from the Hylocereeae altogether, along with the genus Deamia, containing two species that had been placed in either Strophocactus or Selenicereus. To maintain the monophyly of Pseudorhipsalis, Pseudorhipsalis ramulosa was moved to a new genus, Kimnachia, as Kimnachia ...
