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) in the Wet Tropics rainforests region of north-eastern Queensland, Australia.[3][4][5][6] The species has two described varieties, C. araliifolia var. araliifolia and C. araliifolia var. montana, and the common names are used for both.[2][4][5][6]
C. araliifolia var. araliifolia grows naturally in the lowlands and up to the lower parts of the uplands, from about 50 to 1,000 m (160 to 3,280 ft) altitude.[4][6] The trees are recorded as developing into the largest size on basalt derived fertile soils.[4]
C. araliifolia var. montana grows naturally in the uplands, tablelands and mountains of the region, from about 650 to 1,300 m (2,130 to 4,270 ft) altitude, with its variety name referring to mountains.[5][6]
Taxonomy and naming
In 1867, the colonial botanist Ferdinand von Mueller named the species in honour of Henry Herbert, 4th Earl of Carnarvon.[1][2][6][7] In 1995, the Australian tropical rainforest botanist Bernie Hyland updated the description and described the two different varieties.[2][3]
Phylogenetics studies have indicated that C. araliifolia branched off from an early lineage of the plant family Proteaceae and it retains the ancient characteristics. Botanists have classified the species as a member of the subfamily Grevilleoideae because its cotyledons have auricles, which all other Grevilleoideae have and other Proteaceae outside the subfamily do not have.[8]
Description
C. araliifolia grows up to a tall trees in its native rainforest habitats.[3][6] The trunks have a pale grey colour and have rounded buttresses with bases likened to an elephant's foot.[6][7] The compound leaves are up to 35 cm (14 in) long, arranged alternately along the stem. From Nov. to May white–cream flowers grow in panicle–structured compound inflorescences.[6][7] They grow into woody follicle fruits, ripening from July to March with 1 or 2 winged seeds inside, which sulphur-crested cockatoos eat.[6]
