Latin undatus ‘wavy’. For the strongly undulate margins of the ribs, described by Haworth as “somewhat lobed to scalloped” (“sublobulato-crenatis”).
Haworth gave the species the English name Great China triangled Cereus under the assumption that the species was native to China (“Habitat in Sinâ”) and for the similarity to Cereus triangularis (= Selenicereus triangularis).
