Cyma moulding refers not to the decorative motif appearing on the moulding strip – rather to its general shape.  Cyma moulding has a section showing an ogee or double curve; cyma recta has the concave curve on top, cyma reversa has the convex curve on top.

If a moulding is concave, it is known as cavetto.  If it is convex it is known as ovolo.  If it is a semicircle it is called roll moulding.
