HaseltoniaGenerally remains solitary and forms a lateral cephalium. There is only one species, Haseltonia columna-trajani (Karwinsky ex Pfeiffer) Backeberg (= Cephalocereus hoppenstedtii (F.A.C.Weber) K.Schumann). Probably most closely related to Cephalocereus senilis. It is regretably very rare in cultivation and seems to grow very slowly.
