List of vascular plants of Norfolk Island
This is a list of vascular plants that are indigenous to, or naturalised on, Norfolk Island. The list is based on the most recent authoritative treatment of Norfolk Island, the 1994 "Flora of Australia" 49. That source is dated in places; for example its classification of the flowering plants uses the Cronquist system, aspects of which are no longer accepted. This list therefore differs from the "Flora of Australia" treatment in several areas; these are footnoted. List of flora of Norfolk Island.
