Description

Haageocereus pseudomelanostele grows shrubby, sometimes forming groups. The upright shoots are richly branched from the base up to 70 centimeters high and 8 centimeters in diameter. The large areoles are narrow and lined with white wool. The usually only one central spine is initially protruding, later directed downwards, strong, needle-like and up to 5 centimeters long. Sometimes there are additional secondary 3 to 6 central spines with a gray tinge. Numerous yellowish radial spines are up to 1.5 centimeters long and mixed with many white bristles up to 3 centimeters long.

The white flowers are dark purple on the outside and have a greenish-white to red throat. They are about 10 centimeters long. The bright red fruits are ovate, up to 6 centimeters long and 4 centimeters in diameter.[3]
