There's 2,362 species* of native plants in the GBMWHA across 150 families and 619 genera.
[* - species in this case includes subspecies and varieties.]
Here's the list of the GBMWHA native flora species.
Showcased on this webpage are some of the species and their families - a family album.
12 families, between them, contain over 61% of the species; 33 families have only 1 species in the GBMWHA.

- Poaceae (168) - grasses
- Orchidaceae (165) - orchids
- Asteraceae (161) - daisies

Fabaceae * Until recently the Mimosaceae (Acacia) and Caesalpiniaceae (Senna) families were separate families. They are now subfamilies, together with Faboideae (pea flowers), of the Fabaceae family.

Fabaceae (pea flowers and acacias)
Gorse Bitter Pea Daviesia ulicifolia

There are 252 native species of the Fabaceae family in the GBMWHA of which 8 are vulnerable and 6 are endangered.
The endangered species are -
- Acacia bynoeana (Bynoe's Wattle)
- Acacia gordonii
- Acacia pendula (Weeping Myall)
- Pultenaea sp. Genowlan Point (NSW 417813)*
- Pultenaea sp. Olinda (R.Coveny 6616)
- Pultenaea villifera var. villifera**.
* critically endangered.
** endangered population in the Blue Mountains LGA.
The sub-family breakdown is as follows -
- 139 - subfamily Faboideae (pea flowers)
- 108 - subfamily Mimosoideae (acacias)
- 5 - subfamily Caesalpinioideae (senna).
With nearly 20,000 species worldwide, it is the third largest flora family. It could be called the legume, pea and bean family.
Myrtaceae (eucalypts, tea-trees and bottlebrushes)
Scribbly Gum (Eucalyptus racemosa)
Photo: Alan Page
There are 199 native species of the Myrtaceae family in the GBMWHA of which 13 are vulnerable and 6 are endangered. A further 6 species are protected under the
Biodiversity Conservation Act
While all animals and plants classed as threatened species under the Act are protected, several non-threatened species are also protected. An example of this is the Waratah (Telopea speciosissima). Protected species are not to be disturbed.
The endangered species are -
- Baeckea kandos
- Callistemon megalongensis (Megalong Valley Bottlebrush)*
- Eucalyptus macarthurii (Camden Woollybutt)
- Eucalyptus sp. Howes Swamp Creek (M.Doherty 26)
- Rhodamnia rubescens (Scrub Turpentine)*
- Syzygium paniculatum (Magenta Lilly Pilly).
* critically endangered. The Scrub Turpentine was gazetted as critically endangered in 2019.
The 1998 World Heritage Nomination lists 90 Eucalypt taxa. This combines Eucalyptus, Angophora and Corymbia species.
My 2021 study shows 99 species - Eucalyptus (89), Angophora (6) and Corymbia (4). While my new list of GBMWHA Flora has the same number of Angophora and Corymbia species, it has 11 more Eucalyptus species. This difference can be mainly explained by the supplementary list in my 2021 study of 11 possible inclusions.
Commercial products from the myrtaceae family include essential oils (eucalyptus and tea-tree), cloves, guava and allspice.
Poaceae (Grasses)
Grasses after the Black Summer Bushfires

There are 168 native species of the Poaceae family in the GBMWHA of which 1 is vulnerable.
The vulnerable species is Ancistrachne maidenii.
One couldn't help but notice the profusion of native grasses appearing after the Black Summer Bushfires. These grasses helped protect the exposed soils and allowed the seeds from other native flora to germinate and grow. Mother Nature's first responders perhaps.
The Poaceae family includes wheat, corn, rice and bamboo.
Orchidaceae (Orchids)
Spotted Sun Orchid
(Thelymitra ixioides var. ixioides)
Photo: Alan Page
There are 165 native species of the Orchidaceae family in the GBMWHA. All members of this family that are native to NSW are protected.
There are 4 species that are vulnerable and 3 that are endangered.
The endangered species are -
- Diuris aequalis (Buttercup Doubletail)
- Prasophyllum fuscum (Slaty Leek Orchid)*
- Pterostylis saxicola (Sydney Plains Greenhood).
* critically endangered.
At 28,000 species, Orchidaceae, with Asteraceae, is one of the two largest families of flowering plants in the world.
The vanilla bean comes from the Vanilla planifolia orchid.
Asteraceae (Daisies)
Silky Daisy Bush (Olearia erubescens)
Photo: Alan Page
There are 161 native species of the Asteraceae family in the GBMWHA of which 2 are vulnerable and 1 is endangered. A further 3 species are protected.
The vulnerable species are -

The endangered species is - Senecio linearifolius var. dangarensis.
It is noted that it is "restricted to a single known population in the Goulburn River National Park" - which is not in the GBMWHA.
However, this is in close proximity to the Wollemi National Park, and as it is an endangered species it has been retained here to highlight it.
In my 2016 GBMWHA native flora analysis, it was mentioned that Rhaponticum australe (Austral Cornflower or Native Thistle) was an endangered species. It was reclassified in 2021 to being extinct in NSW.
At 32,000 known species, Asteraceae, with orchidaceae, is one of the two largest families of flowering plants in the world.
Plants include lettuces and artichokes, chrysanthemums and dahlias, and the Calendula and Echinacea genera.
