So my gnome has been spending quite a bit of time in Rio de Janeiro lately and he tells me that there is a columnar ornamental cactus that is commonly displayed in front of large appartment complexes. Has anyone spent any time in Rio and know what I'm referring to? They are VERY common in the Zona Sul area, but my gnome tells me he has never actually seen one growing wild anywhere in Rio - just ornamental.
First novice thoughts (or hopes), were that this species may be a Trichocereus Bridgesii, or a Trichocereus Pachanoi. After having examined them more closely, Cereus Peruvianus may be more likely. However, a more educated opinion would be really appreciated (especially since they really resemble a cactus which I previously bought, sold to me as a Trichocereus Bridgesii).
Ok, so the majority of the specimens have 5 ribs, and a few have 4. The largest plants seen were several metres in height, and it was quite common for part of the plant to be bright yellow (it appears to be a common disease for this species - at least in Rio).
I'll include several photographs (the quality of which vary), in the hope that you can help me verify their identity. My gnome was really hoping it might be an active species but he is thinking they are more likely to be a C. Peruvianus
