Neutral Xenomorf On May 4, 2005, Xenomorf from Valley of the Sun, AZ (Zone 9b) wrote:

There is a species name 'Cereus variabilis' that a person named Pfeiffer used in 1837 for this plant, turns out, the name was misapplied to this species [C. fernambucensis].
A person named Engelmann also used 'Cereus variabilis' in 1859 which is now a valid synonym of Acanthocereus tetragonus.
The crested monstrose form of C. fernambucensis in todays market will usually be labeled C. variabilis, which is Still a misapplication of the name.
