Idiospermum is a genus containing a single species of tree, Idiospermum australiense, found in Australian tropical rainforests. The species represents one of the earliest known lineages of flowering plants, dating back as far as 120 million years. It is found today only in the Daintree and Wet Tropics rainforests region of north-eastern Queensland. It is endemic to a very few locations in north-eastern Queensland, in the very wet lowland parts of the forest, in groups of 10–100 trees together. Common names include ribbonwood and idiot fruit.
Grevillea robusta, commonly known as the southern silky oak, silk oak or silky oak, silver oak or Australian silver oak, is a flowering plant in the family Proteaceae. It is a tree, the largest species in its genus but is not closely related to the true oaks, Quercus. It is a native of eastern coastal Australia, growing in riverine, subtropical and dry rainforest environments.
Syzygium paniculatum, the magenta lilly pilly or magenta cherry, is a species of flowering plant in the myrtle family Myrtaceae, native to New South Wales, Australia. A broad dense bushy rainforest tree, in cultivation it grows to a height of 15 m (49 ft) with a trunk diameter up to 35 cm (14 in). The largest known example is at Ourimbah Creek, 35 m (115 ft) metres tall. The leaves are 3–9 cm (1.2–3.5 in) long, opposite, simple and slightly obovate, tapering at the leaf base. They are dark glossy green above, and paler below. White flowers are produced in clusters. The edible fruit is usually magenta, but can be white, pink or purple. Seeds are polyembroynic.
Triunia is a genus of medium to tall shrubs or small trees found as understorey plants in rainforests of eastern Australia. Members of the plant family Proteaceae, they are notable for their poisonous fleshy fruits or drupes. Only one species, T. youngiana, is commonly seen in cultivation.
Eupomatia laurina, commonly named bolwarra, native guava or copper laurel, is a species of plant in the primitive flowering-plant family Eupomatiaceae, endemic to Australia and New Guinea. It grows to between 3 and 5 m tall, but larger specimens may attain a height of 15 m (50 ft) and a trunk diameter of 30 cm (12 in). In Australia, it is found in humid forests of the east coast, from as far south as Nowa Nowa in Victoria, north through New South Wales and Queensland to tropical Cape York Peninsula. It usually grows as an understorey plant in rainforests or humid Eucalypt forests.
Alloxylon brachycarpum is a species of plant in the family Proteaceae. It is found in Indonesia and Papua New Guinea. It is threatened by habitat loss.
Grevillea hilliana, of the plant family Proteaceae, is a species of Australian endemic trees known by many common names including white yiel yiel, white silky oak, grey oak, Hill's silky oak, and yill gill.
Archidendron pauciflorum, commonly known as djenkol, jengkol or jering is a species of flowering tree in the pea family, Fabaceae. It is native to Southeast Asia, where the seeds are a popular dish. They are mainly consumed in Thailand, Malaysia, Myanmar, and Indonesia and prepared by frying, boiling, or roasting and are also eaten raw. The beans are mildly toxic due to the presence of djenkolic acid, an amino acid which causes djenkolism. The beans and leaves of the djenkol tree are traditionally used for medicinal purposes such as purifying the blood. To date, djenkol is traded on local markets only.
Eidothea hardeniana, commonly named nightcap oak, is a species of tree, up to 40 m (130 ft) tall, of the plant family Proteaceae, which botanist Robert Kooyman recognised as a new species only recently in 2002. The species has an official listing as critically endangered on the Australian Commonwealth EPBC Act and as Endangered on the NSW Threatened Species Act. The name hardeniana honours the botanist Gwen Harden. Phylogenetics studies now suggest it represents a basal branch of the Proteoid clade of the Proteaceae.
Stenocarpus salignus, known as the scrub beefwood is an Australian rainforest tree in the family Proteaceae. Found in warmer rainforests on the coast and ranges. It is often found in warm temperate rainforest on poorer sedimentary soils, or on volcanic soils above 750 metres above sea level. It was originally described by the botanist Robert Brown in 1810.
Elaeocarpus bancroftii, commonly known as Kuranda quandong, Johnstone River almond, ebony heart, grey nut, or nut tree is a large rainforest tree in the family Elaeocarpaceae which is endemic to Queensland. It has coriaceous leaves, attractive white flowers and relatively large fruit containing an edible kernel.
Telopea oreades, commonly known as the Gippsland-, mountain- or Victorian waratah, is a large shrub or small tree in the family Proteaceae. Native to southeastern Australia, it is found in wet sclerophyll forest and rainforest on rich acidic soils high in organic matter. No subspecies are recognised, though a northern isolated population hybridises extensively with the Braidwood waratah (T. mongaensis). Reaching a height of up to 19 metres, T. oreades grows with a single trunk and erect habit. It has dark green leaves with prominent veins that are 11–28 centimetres (4.3–11 in) long and 1.5–6 cm (0.6–2.4 in) wide. The red flower heads, known as inflorescences, appear in late spring. Each is composed of up to 60 individual flowers.
Telopea truncata, commonly known as the Tasmanian waratah, is a plant in the family Proteaceae. It is endemic to Tasmania where it is found on moist acidic soils at altitudes of 600 to 1200 m (2000–4000 ft). Telopea truncata is a component of alpine eucalypt forest, rainforest and scrub communities. It grows as a multistemmed shrub to a height of 3 metres (10 ft), or occasionally as a small tree to 10 m (35 ft) high, with red flower heads, known as inflorescences, appearing over the Tasmanian summer and bearing 10 to 35 individual flowers. Yellow-flowered forms are occasionally seen, but do not form a population distinct from the rest of the species.
Eidothea zoexylocarya is a species of tall rainforest trees endemic to north-eastern Queensland, Australia and constituting part of the plant family Proteaceae. In European–Australian science, these trees were only recognised in recent decades, first from the slopes of Mount Bartle Frere, the Queensland mountain which reaches the highest altitude. In 1995, scientific descriptions of the trees, as this genus and type species, were published for the first time by Andrew W. Douglas and Bernie Hyland. The species name refers to the almost identical fossil fruit Xylocaryon lockiiF.Muell., from Ballarat, southern Australia, still extant in this north-eastern Australian species.
Helicia glabriflora is a species of rainforest shrubs or small trees occurring in eastern Australia. Common names include smooth or pale helicia, pale, leather or brown oak. They grow naturally in a variety of different rainforest types from the Illawarra, New South Wales to the Townsville area, Queensland. Of all the global diversity of approximately one hundred Helicia species, this one species naturally grows the furthest south, in the Minnamurra Rainforest and the Robertson area, Illawarra, New South Wales, there observed more on the relatively fertile basalt and alluvial soils.
Archidendron muellerianum, the veiny lace flower or small-flower laceflower, is a rainforest tree with a restricted range in eastern Australia. It is a rare plant, with a ROTAP rating of 3RCa.
Archidendron hendersonii, the white lace flower or tulip siris, is a rainforest tree in eastern Australia. A rare plant, listed as vulnerable, it is named after J.A. Henderson, who collected the original specimen at Ballina.
Guioa acutifolia is an evergreen tree from New Guinea and coastal areas of eastern Queensland in Australia. Common names include glossy tamarind, northern guioa and sharp-leaf guioa. It grows up to 20 metres high and has smooth, grey bark on its trunk which may be up to 15 cm wide. The sweetly scented flowers are produced between August and October in the species' native range Flowers and fruits often appear on immature trees.
Buckinghamia ferruginiflora, also known as Noah's oak or spotted oak, is a species of rainforest tree in the protea family, one of two in the genus that is endemic to the Wet Tropics of Queensland, north-eastern Australia. Although the tree's differences from its congener had been known since the 1970s, it was only formally described by Donald Foreman and Bernard Hyland in 1988 in the journal Muelleria.
Lasjia whelanii, also known as Whelan's silky oak, Whelan's nut oak or Whelan's macadamia, is a species of large forest tree in the protea family that is endemic to north-eastern Queensland, Australia.
