Beautiful columnar cactus that expands branching at the base. Its stems, of pale green colour, are erect, tall and have various tuberculated ribs. The areoles, which may be yellow or grey, are woolly and from them come out the central and radial spines. The central ones are robust and greyish, while the radials are yellow and thin. The flowers grow at the apex of the stem and have varying tonalities; initially they are green-yellow then, when they reach maturity, they get a purple pink tonality.
