Astroloma is an endemic Australian genus of around 20 species of flowering plants in the family Ericaceae.
 The majority of the species are endemic in Western Australia, but a few species occur in New South Wales, Victoria, Tasmania and South Australia.
Derwentia was a genus of flowering plants that is endemic to Australia.
Veronica derwentiana (Derwent speedwell ) is a flowering plant species of the family Plantaginaceae, endemic to south-eastern Australia.
 It is sometimes included in the genus "Parahebe" or "Derwentia".
 It is a woody herb which grows to 140 cm high.
 Leaves are 5 to 20 cm long, with a cuneate, truncate or cordate base and toothed margins.
 The flowers are white, pale lilac or pale blue and appear in 5 to 20 cm long racemes of 40 to 100 flowers in summer.
 The species occurs in a variety of habitats including eucalypt forest and alpine herbfields in Queensland, New South Wales, Victoria, Tasmania and South Australia.
 It is often seen on disturbed sites.
Murray Valley encephalitis virus (MVEV) is a zoonotic flavivirus endemic to northern Australia and Papua New Guinea.
 It is the causal agent of Murray Valley encephalitis (previously known as Australian encephalitis or Australian X disease).
 In humans it can cause permanent neurological disease or death.
 MVEV is related to Kunjin virus which has a similar ecology but a lower morbidity rate.
 Although the arbovirus is endemic to Northern Australia, it has occasionally spread to the southern states during times of heavy rainfall during the summer monsoon season via seasonal flooding of the Murray-Darling river system.
 These outbreaks can be "...decades apart, with no or very few cases identified in between".
Derwentiinae is a subfamily of rhytidosteid temnospondyls from the Permian and Triassic periods of Australia and India.
 It includes the genera "Arcadia", "Deltasaurus", "Derwentia", "Indobrachyops", and "Rewana".
 Derwentiinae was named in a 2011 study that analyzed the phylogenetic relationships of rhytidosteids.
 It was a replacement name for the family Derwentiidae, which was named in 2000.
Myoporum is a genus of flowering plants in the figwort family, Scrophulariaceae (formerly placed in Myoporaceae).
 There are 30 species in the genus, most of which are endemic to Australia although others are endemic to Pacific Islands, including New Zealand, and one is endemic to two Indian Ocean islands.
 They are shrubs or small trees with leaves that are arranged alternately and have white, occasionally pink flowers and a fruit that is a drupe.
Veronica nivea, the milfoil speedwell or snow speedwell, is a flowering plant species of the family Plantaginaceae, endemic to south-eastern Australia.
 It is sometimes included in the genus "Parahebe" or "Derwentia".
Ornithoptera euphorion, the Cairns birdwing, is a species of birdwing butterfly endemic to north-eastern Australia, and is Australia's largest endemic butterfly species.
 Other common names include Cooktown birdwing and northern birdwing.
 The names Cairns and Cooktown in its common names reference the Australian cities in the region where this butterfly is found.
Elsholtzia is a plant genus in the Lamiaceae (mint family).
 It is widespread across much of temperate and tropical Asia from Siberia south to China, India, Indonesia, etc.
Kunzea is a genus of plants in the family Myrtaceae and is endemic to Australasia.
 They are shrubs, sometimes small trees and usually have small, crowded, rather aromatic leaves.
 The flowers are similar to those of plants in the genus "Leptospermum" but differ in having stamens that are longer than the petals. Most kunzeas are endemic to Western Australia but are few occur in eastern Australia and a few are found in New Zealand.
 The taxonomy of the genus is not settled and is complicated by the existence of a number of hybrids.
