Any helpful info appreciated, thanks again!

cereus peruvianus
non-active. but the fruit is tasty

 

[ipumaestro]

all i could say was cereus, dg is legit

 

[Alasdair]

That may be true for specimen B, but what about A? They are two disimilar cacti.

 

[dg]

not 100% sure either is a cereus peruvianus
still neither is an active cactus

just another confirmation - its cereus most likely peruvianus
