This paper discusses path controlled grammars-context-free grammars with a root-to-leaf path in their derivation trees restricted by a control language. First, it investigates the impact of erasing rules on the generative power of path controlled grammars. Then, it establishes two Chomsky-like
normal forms for path controlled grammars-the first allows unit rules, the second allows just one erasing rule.
