Haageocereus pseudomelanostele is a species of plant in the genus Haageocereus from the cactus family(Cactaceae). The specific epithet pseudomelanostele means 'apparently black-stemmed'.
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 stand close together and are covered with white wool. The mostly only one central spine is initially protruding, later also directed downwards, strong, needle-like and up to 5 centimeters long. Sometimes there are additional secondary 3 to 6 central spines with a gray tint. 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 four inches long. The bright red fruits are egg-shaped, up to 6 inches long and 4 inches in diameter.
This species is extremely variable, and different populations have been described as distinct species.
