Description

The plants of the genus Cipocereus are bushy, sometimes branched and columnar growing toreach heights of up to 3.5 m. The cylindrical, somewhat woody shoots are 2 to 5 cm in diameter. On the 4 to 21 ribs are round, white or brown areoles from which a few to many spines arise, which can sometimes be missing and are of variable shape.

The white, tubular flowers open at night and sometimes remain open into the following day. The pericarp and floral tube are ribbed, more or less round in cross-section, and coated with a thick blue wax. The scales are narrow and widely spaced.

The spherical to egg-shaped, not splitting fruits are overgrown with intensive grey-blue. The remainder of the flowers is perennial. The brownish black to black, more or less dull seeds are broadly oval and 1 to 2 millimeters long.
