Hi! I was trying to add this plant as I didn't see it in the database and this came up, but I don't know another genus name for this plant other than Trichocereus. Thank you

Try looking at Echinopsis lageniformis and see if that works.

Bolivian Torch (Echinopsis lageniformis)

Trichocereus bridgesii is a synonym for the one greene mentioned and Baja linked to, I just added it to that entry so it will come up in a search now.

(I am surprised that I actually knew the answer!! Some knowledge may be sinking into this old brain on mine. )

So that plant is a monstrose form of the actual plant so probably should have its own entry with 'monstrose' or a cultivar name added. If this gets added to the actual regular entry for the plant it will be highly confusing as the regular version of the plant does not look like that.

Also, I am not sure how long it will take to be reflected in the CoL, but afaik Trichocereus has been reinstated by the committee/working group that deals with cactus nomenclature in the last few years. For example in the latest version of the New Cactus Lexicon this plant is now called Trichocereus lageniformis. Not sure why they did not go back to Trichocereus bridgesii, but they did not.

Anyway, the last bit is not really that pertinent to the discussion here, just giving people a heads up as to what might be coming...

Very very interesting on that last part! I have just known it to be T. bridgesii so it's cool to hear synonyms.

I do agree about the monstrose addition because this looks absolutely nothing like the not-monstrose form! People would see that and be like "excuse me....?"
