genus that includes some species of columnar cacti, originating in southern America, especially in Brazil. In nature they reach 2-3 meters in height, while in containers they remain close to 60-80 cm. They grow slowly and initially develop for some years as a globose cactus; they have a dark green stem, crossed by 5-15 ribs, which bear numerous spiny areoles; the thorns are yellowish, but become gray with the passage of time. The exemplary specimens develop at the top a cephalio, consisting of hairs and thorns of brown or black color; these plants, unlike the melocactus, grow in height even after developing the cephalio, which tends to become lateral over time. In summer from the cephalio numerous flowers bloom, 7-10 centimeters long, of white, red or pink color; the flowers are only open at night. The flowers are followed by small oval fruits, containing numerous seeds, which generally sprout a few millimeters from the cephalio.
