Cleistocactus is a genus of columnar cacti from Peru, Uruguay, Bolivia and Argentina. The name comes from the Greek kleistos meaning closed because the flowers hardly open.
The stems are tall and mostly slender and often many branched with numerous ribs with closely set areoles and spines. The flowers are tubular and the tips hardly open with only the style and stamens usually protruding.
