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.
