Many of Lamington's plants are found nowhere else on earth, such as O’Reilly's pittosporum ("Pittosporum oreillyanum"), the Lamington peach myrtle ("Uromyrtus lamingtonensis"), and the Mt Merino eyebright and Everlasting Daisy which are subalpine relics from the last ice age. In 2006 it was realised that an old collection of the eastern underground orchid ("Rhizanthella slateri") from Lamington was actually a separate species and has been described as the Lamington underground orchid ("Rhizanthella omissa"). This orchid, like the two other related species, has no chlorophyll and depends entirely upon a symbiotic fungus for survival. It is also one of only four flowering plants on Earth to complete its life cycle entirely underground. Sadly, one of Lamington's more than 100 fern species is now presumed extinct; "Antrophyum austroqueenslandicum" was known from only a single plant which has since died and no other plants have been found. Lamington is also home to a large number of threatened plant species such as the ravine and blotched "Sarchochilus" orchids. Strangler figs are also found in Lamington.
