I think you're right. Clearly not peruvianus. Thanks!

Thanks for your reply. The more they grow, the less they look like Peruvianus... Probably Weberbauerocereus longicomus as Catimaniac suggested below.

Hello, I grew from seed 18 months ago what I was told were Echinopsis peruviana. They are now roughly 10 cm high, but 3 out of the 9 cacti look like the one on the right. Are they all Echinopsis peruviana or did I have some seeds of a closely related species mixed in there? Echinopsis_peruviana3.jpg...
