Darlingia ferruginea, commonly known as the brown silky oak, is a rainforest tree of the family Proteaceae from Northern Queensland.

Taxonomy and naming

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]

Description

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]

Distribution and habitat

Darlingia ferruginea is found in montane rainforests from altitude 650 to 1300 m on the Atherton Tableland. [4]

Uses and cultivation

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, and accordingly unrelated to true oaks, family Fagaceae. Grevillea robusta is a tree, and is the largest species in its genus. It is a native of eastern coastal Australia, growing in riverine, subtropical and dry rainforest environments.

<i>Athertonia</i> Monotypic genus of trees in the family Proteaceae

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.

<i>Alloxylon flammeum</i> Species of tree in the family Proteaceae

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.
