Floydia praealta | |
Floydia is a monotypic genus of plants in the Proteaceae family endemic to Australia. The sole described species is Floydia praealta, commonly known as the ball nut. It is a somewhat rare tree found only growing in the rainforests of southeastern Queensland and northeastern New South Wales. The tree has a superficial resemblance to the closely related Macadamia and could be confused with them. The fruit is poisonous.
Floydia praealta is a tree growing to 30 m (98 ft) tall with a trunk up to 60 cm (24 in) diameter. The leaves are mid-green, shiny, glabrous and stiff. [1] [2] They measure up to 25 cm (9.8 in) long by 3 cm (1.2 in) wide and are held on a petiole up to 1.2 cm (0.47 in) long. [1] [2] There are between 10 and 28 pairs of secondary veins and a densely reticulate tertiary venation which are all obvious on both surfaces. [1] [2]
The inflorescence is a raceme up to 20 cm (7.9 in) long carrying numerous cream flowers in pairs. The flowers have 4 hairy tepals and are up to 1.7 cm (0.67 in) long. [2] [5] The fruit is a globular, woody follicle around 3 or 4 cm (1.2 or 1.6 in) diameter. [1] [2] [5]
The species was formally described in 1862 by Victorian Government Botanist Ferdinand von Mueller based on plant material collected near the Clarence River in northern New South Wales and the Brisbane River in Queensland. In his publication Fragmenta phytographiæ Australiæ Mueller named the plant Helicia praealta. The species was transferred to the genus Macadamia in 1901 by Queensland Colonial Botanist Frederick Manson Bailey and then to Floydia in 1975 by Lawrie Johnson and Barbara Briggs. [1] [4]
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.
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.
Alloxylon flammeum, commonly known as the Queensland tree waratah or red silky oak, is a medium-sized tree of the family Proteaceae found in the Queensland tropical rain forests of northeastern Australia. It has shiny green elliptical leaves up to 18 cm (7.1 in) long, and prominent orange-red inflorescences that appear from August to October, followed by rectangular woody seed pods that ripen in February and March. Juvenile plants have large deeply lobed pinnate leaves. Previously known as Oreocallis wickhamii, the initial specimen turned out to be a different species to the one cultivated and hence a new scientific name was required. Described formally by Peter Weston and Mike Crisp in 1991, A. flammeum was designated the type species of the genus Alloxylon. This genus contains the four species previously classified in Oreocallis that are found in Australasia.
Hymenosporum is a monotypic genus of trees in the family Pittosporaceae. The sole included species is Hymenosporum flavum, commonly known as native frangipani, found in the rainforests and wet sclerophyll forests of New Guinea, Queensland and New South Wales. Despite its common name, it is not closely related to the frangipani, but is related to the widespread genus Pittosporum.
Helicia australasica, also known as Austral oak or creek silky oak, is a species of rainforest tree in the macadamia family Proteaceae, native to New Guinea and northern and northeastern Australia.
Cardwellia is a monotypic genus in the plant family Proteaceae. The sole described species is Cardwellia sublimis − commonly known as northern silky oak, bull oak or lacewood − which is endemic to the rainforests of northeastern Queensland, Australia.
Guioa semiglauca, known as the guioa or wild quince, is a rainforest tree of eastern Australia It grows from Kioloa near Batemans Bay in southern New South Wales to Eungella National Park in tropical Queensland. It grows in many different types of rainforest, particularly common in regenerating areas and on sand in littoral rainforest.
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.
Hicksbeachia pinnatifolia is a small tree in the family Proteaceae. Common names include red bopple nut, monkey nut, red nut, beef nut, rose nut and ivory silky oak.
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.
Atractocarpus chartaceus, commonly known as the narrow-leaved gardenia, is a species of evergreen flowering plant in the coffee family Rubiaceae. It is found in subtropical rainforest of eastern Queensland, Australia, and it is cultivated for its fragrant flowers and colourful fruit.
Atractocarpus fitzalanii, commonly known as the brown gardenia or yellow mangosteen, is a species of plant in the coffee and madder family Rubiaceae. It is found in coastal parts of tropical Queensland, Australia. The beautifully scented flowers and glossy foliage has seen this plant enter cultivation in gardens of eastern Australia.
Endiandra discolor is a tree in the family Lauraceae, native to eastern Australia from central New South Wales to northeastern Queensland. Common names include rose walnut and domatia tree. It grows in tropical, subtropical or warm temperate rainforest, particularly on the poorer volcanic soil types, and alluvial soil near streams. It was first described in 1870, and has been given the conservation status of least concern.
Alloxylon pinnatum, known as Dorrigo waratah, is a tree of the family Proteaceae found in warm-temperate rainforest of south-east Queensland and northern New South Wales in eastern Australia. It has shiny green leaves that are either pinnate (lobed) and up to 30 cm (12 in) long, or lanceolate (spear-shaped) and up to 15 cm (5.9 in) long. The prominent pinkish-red flower heads, known as inflorescences, appear in spring and summer; these are made up of 50 to 140 individual flowers arranged in corymb or raceme. These are followed by rectangular woody seed pods, which bear two rows of winged seeds.
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.
Opisthiolepis is a monotypic genus of trees in the macadamia family Proteaceae. The sole species is Opisthiolepis heterophylla, commonly known as blush silky oak, pink silky oak, brown silky oak or drunk rabbit. It was first described in 1952 and is endemic to a small part of northeastern Queensland, Australia.

Lasjia is a genus of six species of trees of the family Proteaceae. Three species grow naturally in northeastern Queensland, Australia and three species in Sulawesi, Indonesia. Descriptively they are the tropical or northern macadamia trees group. Lasjia species characteristically branched compound inflorescences differentiate them from the Macadamia species, of Australia, which have characteristically unbranched compound inflorescences and only grow naturally about 1,000 km (620 mi) further to the south, in southern and central eastern Queensland and in northeastern New South Wales.
Dillenia alata, commonly known as red beech, golden guinea flower or golden guinea tree, is a tree in the Dilleniaceae family, found in New Guinea, and the Northern Territory and Queensland in Australia. It has found some popularity as an ornamental for tropical parks and large gardens due to its colourful flowers and fruit.
