What are three threatened or rare plants of Australia?

Three threatened or rare plants of Australia are:

1. Wollemi pine (_Wollemia nobilis_): This coniferous tree is endemic to Australia and was previously thought to be extinct. It was discovered in 1994 in a remote canyon in Wollemi National Park in New South Wales. The Wollemi pine is a living fossil that has remained unchanged for over 200 million years. It is classified as critically endangered due to its limited population and habitat.

2. Christmas Island scrub ironwood (_Serianthes nelsonii_): This evergreen tree is endemic to Christmas Island in the Indian Ocean, which is part of Australia. It is a vulnerable species due to habitat loss, invasive species, and illegal logging. The Christmas Island scrub ironwood is known for its beautiful purple flowers and is an important food source for local bird species.

3. Western Australian featherflower (_Verticordia nitens_): This shrub is endemic to the southwestern region of Western Australia. It is listed as endangered due to habitat loss, habitat fragmentation, and illegal collection.
