Echinopsis cephalomacrostibas is a species of the genus Echinopsis in the cactus family(Cactaceae). The specific epithet cephalomacrostibas is derived from the Greek words kephale for 'head', macros for 'large' and stibas for 'bed' and refers to the large areoles that almost converge near the shoot tips.

description

Echinopsis cephalomacrostibas grows shrubby and forms dense groups of up to 2 meters in height. The cylindrical, gray-green shoots reach a diameter of up to 10 centimeters. There are eight broad ribs that are furrowed across. The conspicuous areoles on it are brown and are crowded at the shoot tips. The one to four very strong central spines are curved backwards and interlocking. They are dark brown and gray with age. The central spines are sometimes angular and runny. They are up to 12 inches long. The up to 20 radial spines are sub-like and very short.

The funnel-shaped, white flowers open at night. They become up to 12 centimeters long and reach a diameter of 10 centimeters. The spherical to elongated fruits are reddish to yellowish orange.
