Etymology

Greek koleon ‘sheath, cabbard’ + Cephalocereus. Presumably for the “channelled cephalium” (as opposed to the “exterior cephalium” of Cephalocereus) with the flowers arising from the channels. Not for “the green bracts, which gradually change into colored petals” (Genaust, Etymologisches Wörterbuch der botanischen Pflanzennamen. 3. Auflage. 1996), a characteristic not mentioned by Backeberg.
