I would say the other is still Ivy, just a different variety .
They come in a wide variety of leaf shapes and sizes, I have one with leaves
growing to over 10 inches in width.
As a point of interest, If you want to grow an "Ivy Bush", then take
cuttings from the Ivy high up where it has changed from a climber to a
shrubby plant, these plants when rooted will keep the bushy habit and wont
revert to climbing
