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.
The tree was first described in 1889 by Queensland's colonial botanist Frederick Manson Bailey as a species of Helicia , which in 1901 he moved to Macadamia , but was transferred in 2008, in a paper in the American Journal of Botany by Peter Weston and Austin Mast, to the new genus Lasjia.
The dark green leaves are 6–21.5 cm long by 2–6.5 cm wide, with four or five leaves in each whorl. The white flowers grow as inflorescences. The globular fruits are 4–5 cm in diameter, with the seeds strongly cyanogenetic (cyanide producing) and poisonous to humans. It produces a useful timber, suitable for construction work. [1]
The species occurs in the Wet Tropics of Queensland, in well-developed lowland tropical rainforest, from near sea level to an altitude of 650 m. [1]
Macadamia is a genus of four species of trees in the flowering plant family Proteaceae. They are indigenous to Australia, native to northeastern New South Wales and central and southeastern Queensland specifically. Two species of the genus are commercially important for their fruit, the macadamia nut. Global production in 2015 was 160,000 tonnes. Other names include Queensland nut, bush nut, maroochi nut, bauple nut and Hawaii nut. In Australian Aboriginal languages, the fruit is known by names such as bauple, gyndl or jindilli and boombera. It was an important source of bushfood for the Aboriginal peoples who are the original inhabitants of the area.
Athertonia is a genus of tall trees, constituting part of the plant family Proteaceae. It is a monotypic taxon, and the sole described species is Athertonia diversifolia, commonly known as Atherton oak. It is a small to medium-sized tree and is endemic to restricted tablelands and mountainous regions of the wet tropics rain forests of north-eastern Queensland, Australia, where it is widespread. For example, it grows in the Atherton Tableland region with which it shares its name, from the colonial pastoralist John Atherton (1837–1913). Its closest relatives are Heliciopsis and Virotia. A relative of the macadamia, it has potential as an ornamental tree and has an edible nut.
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.
Buckinghamia is a genus of only two known species of trees, belonging to the plant family Proteaceae. They are endemic to the rainforests of the wet tropics region of north eastern Queensland, Australia. The ivory curl flower, B. celsissima, is the well known, popular and widely cultivated species in gardens and parks, in eastern and southern mainland Australia, and additionally as street trees north from about Brisbane. The second species, B. ferruginiflora, was only recently described in 1988.
Macadamia tetraphylla is a tree in the family Proteaceae, native to southern Queensland and northern New South Wales in Australia. Common names include macadamia nut, bauple nut, prickly macadamia, Queensland nut, rough-shelled bush nut and rough-shelled Queensland nut.
Macadamia integrifolia is a small to medium-sized tree, growing to 15 metres in height. Native to rainforests in south east Queensland and northern New South Wales, Australia. Common names include macadamia, smooth-shelled macadamia, bush nut, Queensland nut, Bauple nut and nut oak.
Cardwellia is a genus of a sole described species of large trees in the plant family Proteaceae. The species Cardwellia sublimis is endemic to the rainforests of the wet tropics region of northeastern Queensland, Australia. Other common names include bull oak, golden spanglewood, lacewood, oak and oongaary. The compound leaves have up to 17 leaflets. It produces white inflorescences followed by woody fruits which are prominently displayed outside the canopy.
Hicksbeachia pinnatifolia is a small tree in the family Proteaceae. This rare species is native to subtropical rainforest in New South Wales and Queensland in Australia. Common names include red bopple nut, monkey nut, red nut, beef nut, rose nut and ivory silky oak. The tree produces fleshy, red fruits during spring and summer. These contain edible seeds.
Darlingia ferruginea, commonly known as the brown silky oak, is a rainforest tree of the family Proteaceae from Northern Queensland.
Opisthiolepis is a genus of a sole described species of large trees, constituting part of the plant family Proteaceae. The species Opisthiolepis heterophylla most commonly has the names of blush silky oak, pink silky oak, brown silky oak and drunk rabbit.
Placospermum is a genus of a single species of large trees, constituting part of the plant family Proteaceae. The species Placospermum coriaceum is endemic to the rainforests of the wet tropics region of northeastern Queensland, Australia. Common names include rose silky oak and plate-seeded oak.
Catalepidia is a genus of a sole described species of medium-sized trees, constituting part of the plant family Proteaceae. The species Catalepidia heyana grows naturally only in a restricted mountain region (endemic) of the wet tropics rain forests of north-eastern Queensland, Australia. Common names include Hey's nut or Hey's nut oak.
Carnarvonia is a flowering plant genus of a single species, commonly named red oak or red silky oak and constituting part of the plant family Proteaceae. The single species named Carnarvonia araliifolia grows to large trees of 30 m (100 ft) or more. They grow naturally only (endemic) to the Wet Tropics rainforests region of north-eastern Queensland, Australia. The species has two described varieties, C. araliifolia var. araliifolia and C. araliifolia var. montana, and the common names are used for both.
Lasjia is a genus of five species of trees of the family Proteaceae. Three species grow naturally in northeastern Queensland, Australia and two 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.
Macadamia ternifolia is a tree in the flowering plant family Proteaceae, native to Queensland in Australia, and is listed as vulnerable under the EPBC Act.
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 claudiensis is a species of tree in the protea family that is endemic to the Cape York Peninsula of Far North Queensland in north-eastern Australia. It is listed as Vulnerable under Queensland's Nature Conservation Act 1992 as well as Australia's Environment Protection and Biodiversity Conservation Act 1999.
Lasjia grandis, also known as the satin silky oak or Barong nut, is a species of forest tree in the protea family that is endemic to north-eastern Queensland, Australia. Its conservation status is considered to be Vulnerable under Queensland's Nature Conservation Act 1992.
Lasjia hildebrandii, also known as Celebes nut, Sulawesi nut, Sulawesi macadamia or Hildebrand's macadamia, is a species of forest tree in the protea family that is endemic to the island of Sulawesi, Indonesia. Its closest relative is Lasjia erecta, also a Sulawesi endemic.
Lasjia erecta is a species of forest tree in the protea family that is endemic to the island of Sulawesi, Indonesia. Its closest relative is Lasjia hildebrandii, also a Sulawesi endemic.
