Harrisia tortuosa is a species of cactus in the Trichocereeae tribe.[2]
Harrisia tortuosa grows as a shrub with upright or later arched or prostrate, dark green shoots that are up to 1 meter long with diameters of 2 to 4 centimeters. There are usually seven rounded, slightly tuberous ribs. The one to three strong central thorns, initially red, later become almost black. They are 3 to 4 centimeters long. The six to ten pale and light-colored marginal spines reach a length of up to 2 centimeters.
The flowers reach a length of up to 16 centimeters. The spherical, bumpy red fruits have a few thorns and reach a diameter of 3 to 4 centimeters.[3]
