The "hat boxes" clear rows, they have a horizontal or vertical stripe on them to indicate which row. The "swirling cauldron" clears the direct area and the "treasure chest" clears everything of one colour.

You can get the two leaves/scrolls etc. by eliminating them with a hat box or cauldron, and maybe (I'm not sure if I recall correctly) by dropping them through the bottom row like the sun/moon.
