Austrobaileya is the sole genus consisting of a single species that constitutes the entire flowering plant family Austrobaileyaceae. The species Austrobaileya scandens grows naturally only in the Wet Tropics rainforests of northeastern Queensland, Australia.
Idiospermum is a monotypic genus in the family Calycanthaceae. The sole included species is Idiospermum australiense − commonly known as idiotfruit, ribbonwood, or dinosaur tree − which is found only in two small areas of the tropical rainforests of northeastern Queensland, Australia. It is a relic of the ancient forests of Gondwana, surviving in very localised refugia for 120 million years, and displaying features that are almost identical to fossil records from that time. As such it provides an important insight into the very early evolution of flowering plants.
Agathis robusta, commonly known as kauri pine, Queensland kauri (pine), Australian kauri (pine) or smooth-barked kauri, is a coniferous tree in the family Araucariaceae. Although sometimes called a pine it is not a true pine, having leaves rather than needles. It has a disjunct distribution, occurring in Papua New Guinea and Queensland, Australia. Populations in Papua New Guinea may be treated as the distinct species Agathis spathulata.
Athertonia is a monotypic genus of plants in the family Proteaceae. The sole described species is Athertonia diversifolia, commonly known as Atherton oak, athertonia, creamy silky oak or white oak. It is endemic to a small part of the Wet Tropics of Queensland, Australia. A relative of the macadamia, it has potential in horticulture and the bushfood industry.
Romnalda is a genus of monocotyledonous plants in the family Asparagaceae, subfamily Lomandroideae. As of December 2013 four formally named species are known and accepted by botanical science.
Lepiderema is a genus of nine species of trees from the family Sapindaceae. As of November 2013 botanists know of seven species growing naturally in Australia and two species in New Guinea. Published botanical science provides a limited knowledge of the full range of diversity in Australia and especially in New Guinea. In New Guinea the two known species have descriptions based each on only a single type specimen collection. Therefore, collection of more specimens and more species is most likely in New Guinea. In Australia they grow in rainforests of the northern half of the east coast side of the Great Dividing Range, from northeastern New South Wales through to northeastern Queensland.
Neolitsea dealbata, also known as white bolly gum, hairy-leaved bolly gum, or simply bolly gum, is a shrub or small tree in the laurel family Lauraceae which is native to New South Wales and Queensland in Australia.
Normanbya is a monotypic genus of palms containing the single species Normanbya normanbyi, which is known by the common name black palm It is endemic to Queensland, Australia and is threatened by habitat destruction.
Alpinia caerulea, commonly known as native ginger or Australian ginger, is an understorey perennial herb in the family Zingiberaceae which grows in rainforest, gallery forest and wet sclerophyll forest in eastern Australia.
Cyril Tenison White was an Australian botanist.
Phaleria clerodendron, commonly known as scented daphne, scented phaleria or rosy apple, is an evergreen tree or tall shrub in the family Thymelaeaceae. It is endemic to the rainforests of north-eastern Queensland, Australia.
Hedraianthera is a genus of a sole recognised species of shrubs or small trees endemic to Australia from the family Celastraceae.
Stockwellia is a monotypic genus in the flowering plant family Myrtaceae. The sole species in the genus, Stockwellia quadrifida, is endemic to Queensland.
Gardenia actinocarpa is a rare and endangered plant in the madder family Rubiaceae that grows in a very restricted area within the Wet Tropics rainforest of north-east Queensland.
Atractocarpus hirtus, commonly known as the hairy gardenia or native loquat, is a plant in the madder family Rubiaceae, a large family of some 6,500 species with a cosmopolitan distribution. This species is endemic to northeastern Queensland, Australia.
Alstonia muelleriana is a tree in the dogbane family Apocynaceae which is native to southern Papua New Guinea and northeastern Queensland.
Meiogyne hirsuta is a plant in the family Annonaceae endemic to the Wet Tropics of Queensland in Australia. It is known from only a small number of collections from three widely separated locations in the Wet Tropics, namely Cedar Bay near Cooktown, the lower reaches of Mossman Gorge, and the foothills of the southern Atherton Tablelands in the vicinity of the North Johnstone River.
Polyosma hirsuta, commonly known as hairy polyosma, is a plant in the family Escalloniaceae which is endemic to northeastern Queensland, Australia. It is an evergreen small tree growing up to 10 m (33 ft) high. The leaves may be 6 to 14 cm long and 2 to 5 cm wide, often with toothed margins and each tooth exhibiting a short stiff spine. Most parts of the plant, including the twigs, leaves and fruit, are clothed in fine pale brown hairs.
Polyosma rhytophloia, commonly known as wrinkled bark polyosma, is a plant in the family Escalloniaceae which is endemic to parts of eastern Queensland, Australia. It is an evergreen small tree growing up to 11 m (36 ft) high. The glabrous (hairless) leaves may be 7 to 12 cm long and 2 to 6 cm wide, with a number of very fine teeth along the margins. The veins are prominent on both sides of the blade, and the midrib is often purple on the underside.
Harpullia rhyticarpa, commonly known as slender harpullia, is a plant in the family Sapindaceae which is endemic to the rainforests northeastern Queensland, Australia.
