Etymology

Named for Cuban botanist Alberto Areces-Mallea (1947-), who published Cereus subgen. Neohaiticereus for Cereus serruliflorus, which he considered conspecific with Cereus haitiensis (= Cereus ayisyen). Wisnev considered Cereus serruliflorus a synonym of Harrisia divaricata, which renders Cereus subgen. Neohaiticereus a synonym of Harrisia, and published the new subgenus Arecesocereus for Cereus haitiensis (= Cereus ayisyen), which he considered a separate species.
