Darlingia ferruginea, commonly known as the brown silky oak, is a rainforest tree of the family Proteaceae from Northern Queensland.
Queensland botanist John Frederick Bailey described Darlingia ferruginea in 1899. [1] The species name is the Latin adjective ferruginea "rusty", and refers to the rust-coloured fur on the stems and leaves. [2]
Molecular analysis indicates Darlingia ferruginea and its relative D. darlingiana join Floydia prealta as members of the subtribe Floydiinae within the subfamily Grevilleoideae in the family Proteaceae. [3]
Common names include brown silky oak, rose silky oak, [1] and rusty silky oak. [4] Its everyday name in the local Dyirbal language was gurray, though a more general word gurruŋun "oak tree" (also applied to Cardwellia sublimis and Helicia australasica ) was used in the taboo [Dyalŋuy] vocabulary. [5]
Darlingia ferruginea grows as a tall tree in its native rainforest habitat, forming part of the canopy and reaching 30 m (100 ft) in height, though likely to only grow a third this size in cultivation. The trunk is not buttressed. [2] The initial leaves are entire but juvenile leaves are lobed, reaching 70 cm (28 in) long. The leaf veins and undersurface, and stems are covered with fine rust-coloured hairs. [2] Adult leaves are entire and measure 20-46 long by 5–21 cm wide. [4] Flowering is in winter and early spring, the inflorescences are 14–22 cm long. [6]
Darlingia ferruginea is found in montane rainforests from altitude 650 to 1300 m on the Atherton Tableland. [4]
Darlingia ferruginea has potential as a specimen tree in parks, and has showy flowers and foliage. It is readily propagated from seed or cuttings. [2]
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.
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.
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.
Orites excelsus, commonly known as prickly ash, mountain silky oak or white beefwood, is a species of flowering plant in the family Proteaceae and is endemic to eastern Australia. It is a medium-sized to tall rainforest tree with oblong to lance-shaped leaves, variously lobed and with teeth on the edges. The flowers are white and arranged in leaf axils in spikes that are shorter than the leaves.
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.
Helicia australasica, also named Austral oak or creek silky oak, is a species of rainforest trees from the flowering plant family Proteaceae.
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.
Stenocarpus sinuatus, known as the firewheel tree, is an Australian rainforest tree in the family Proteaceae. The range of natural distribution is in various rainforest types from the Nambucca River in New South Wales to the Atherton Tableland in tropical Queensland. Stenocarpus sinuatus is widely planted as an ornamental tree in other parts of Australia and in different parts of the world.
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.
Grevillea edelfeltii, commonly known as white oak, is a tree of the family Proteaceae and is native to the rainforests of north-east Queensland in Australia and to Papua New Guinea.
Stenocarpus cryptocarpus, commonly known as the giant-leaved stenocarpus, is a species of flowering plant in the family Proteaceae and is endemic to north Queensland. It is a tree with buttress roots at the base, simple, mostly elliptical adult leaves, groups of cream-coloured flowers and narrow oblong follicles.
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.
Silky oak is a common name for Grevillea robusta.
Buckinghamia celsissima, commonly known as the ivory curl tree, ivory curl flower or spotted silky oak, is a species of tree in the family Proteaceae. It is endemic to the tropical rainforests of northeastern Queensland, Australia.
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.
Helicia ferruginea, commonly named hairy honeysuckle or rusty oak, is a species of rainforest trees, of eastern Australia, from the flowering plant family Proteaceae.
Stenocarpus verticis is a species of flowering plant in the family Proteaceae and is endemic to northern Australia. It is a tree with elliptic or lance-shaped adult leaves and groups of cream-coloured flowers covered with woolly, rust-coloured or grey hairs.
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 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.
