I was wondering what features can reliably recognize a macrogonus.
My personal opinion is that if it did not descend from the Berlin Botanical Gardens it can't really be proven to be a macrogonus and that the name and description should be chucked as invalid but that is hardly useful in the real world since so many macrogonuses exist out there that are reliably distinct from the peruvianus sorts.
Some people try to stuff a bunch of clearly peruvianus plants into it (which is clearly wrong since peruvianus branches can grow to around 15 or more feet and those of macrogonus only get to around 6 - sometimes a bit longer if jointed and prostrate)
Awlshaped spines, brown from the start, at least for a short while, seems the only unique thing in the description but this is not reliably true in the real world.
I'd love to hear opinions on how people recognize theirs. Not to find people to disagree with but to try and sort out what makes a macrogonus a macrogonus.

Yeah, the one on the left is the plant type which commonly gets called T. macrogonus. Whether or not what we call T. macrogonus matches the German holotype plant is unknown, but I've leaned towards t

I've come to the conclusion that adding the name "T. macrogonus" into the mix just dirties the water more as if it is recognized it would probably have the same flower characteristics as both the Ecua

There is one very reliable segregator of peruvianus and pachanoi. That being the length of the tube being much shorter in peruvianus. Intermediates (hybrids?) abound and tend more towards pachanoi in
