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 Australia49. 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.
Norfolk Island has 523 taxa of vascular plants, 136 of which are indigenous, and 387 naturalised. Forty-four of the indigenous taxa are endemic. There are two endemic genera, Ungeria and Streblorrhiza.
The Monocotyledons (monocots) are represented on Norfolk Island by 16 families, 81 genera, and 110 species. Most of them are naturalised, with naturalised grasses account for 5 families, 47 genera and 67 species. Of the 43 indigenous species, 9 are endemic.
At least one putative collection of Euchiton involucratus from Norfolk Island has now been identified as Euchiton sphaericus. Whether E.involucratus also occurs on Norfolk Island is now uncertain.
Flora of Australia lists Geranium gardneri as naturalised in Norfolk Island, but the variant of G.gardneri that occurs on Norfolk Island has since been published as G.gardneri in de Lange et al. (2005)
Cryptocarya triplinervis was excluded from Flora of Australia as a probable erroneous collection, but has since been collected a number of times, and was admitted by de Lange et al. (2005).
Flora of Australia treated all of the Oxalis species on Norfolk Island as Oxalis corniculata. This complex is now usually treated as five distinct species, of which four occur on Norfolk Island.
Pennantia endlicheri was not listed as endemic in Flora of Australia, as the Manawatāwhi / Three Kings Islands populations of Pennantia were then considered members of that species. These are now treated as P.baylisiana, and P.endlicheri is considered endemic to Norfolk Island.
Boehmeria australis subsp. australis was listed as Boehmeria australis var. australis in Flora of Australia. It was automatically promoted to subspecies rank when de Lange et al. (2005) promoted the Kermadec Islands taxon Boehmeria australia var. dealbata to subspecies rank.
Flora of Australia listed Rhopalostylis baueri var. baueri as an endemic variety, but the varieties were demoted to synonymy with R.baueri in de Lange et al. (2005). The species is not endemic.
Flora of Australia listed the Oplismenus hirtellus; de Lange et al. (2005) refined this to subspecies level as O.h. subsp. hirtellus and O.h. subsp. imbecillus
Flora of Australia does not include Nephrolepis flexuosa, as this name was then considered synonymous with Nephrolepis cordifolia. It was re-instated as a current species name by de Lange et al. in 2005.
