Ohh such a cutie....
Dave they are similar except the veins in A. clarinervium don't "sparkle"quite the the A. crystallinum.
I managed to get a nice sized plant for a very good price recently of the A. crystallinum, so for now my lust for the A. clarinervium is tamed a bit. But...If I run across and good deal most likely I'll end up with it also.
