This trichocereus species is most closely related to trichocereus peruvianus, although seeds and specimens are less readily available. Also a relative of trichocereus bridgesii and trichocereus pachanoi, macrogonus grows wild in Ecuador, Peru and Bolivia. It is characterized by its bluish-green skin, thick stems and multiple brown spines. Macrogonus is said to be the fastest-growing of all trichocereus species.
