Great chart. Thank you.
I often have people come to me with Polaskia chichipe thinking that they have a trichocereus species, it resembles trichocereus peruvianus, Maybe a Pachanoi, one key difference is that Polaskia chichipe has dark red spines... any way, I often encounter many of the cacti listed below that some individual had thought in error was a trichocereus, I hope this can aide in teaching others how to recognize trichocereus cacti and their look alikes.
The link in the quotation box below elucidates common trichocereus look-alikes, and provides photographs, it's not the best, but it's a good start.

You can ID cacti for people, or you can teach them how to do it themselves...
(Though I do enjoy the challenge of plant and fungi ID, it's a more productive use of my time to offer resources to teach others how to ID)
http://sacredcacti.com/w...BySpecies_2014_Light.pdfThis PDF lists cactus species and their chemistry, it has been a valuable tool in my research, there is a better version packed with photos, but it takes up a good deal of space.
