Is flat leaf parsley the same as Italian parsley?

"Curly parsley has a pleasant grassy flavor and decorative ruffled leaves that make it the perfect garnish. When a stronger flavor is desired, recipes usually call for flat-leaf or Italian parsley (they're the same), which features broad, serrated leaves."

The culinary herb parsley, comes in two basic types, curly and flat leafed (sometimes called Italian Parsley). Both types are readily available in fresh or dried forms and are simple herbs to grow even in very small spaces and/or containers.

The flat leafed type is more commonly used in cooking as it has a somewhat more robust flavour.
