Lorax gave the best explanation that I've heard in a long time, including the exceptions.

For those who didn't know that a leaf has sinuses and wish an English translation of "fusion of the posterior lobes" and how an average Joe can remember how to tell an alocasia from a colocasia, here is the easy way:

Colocasia (starts with a "C") has the leaf stem coming from a more centered (starts with a "C") spot on the leaf. Those fused lobes make the leaf wrap around the stem more.

Alocasia (starts with "A") has the leaf stem coming from the edge of the leaf (nearly, and ignoring the lobes) and thus the leaf & leaf stem look like an arrow (starts with "A") with the shaft broken right behind the head. There is little or no fused lobe behind the stem.

Now, go back and look at the pictures and you'll see what I mean.
