Denhamia fasciculiflora, commonly known as orange bark, is a plant in the family Celastraceae found only in Queensland, Australia.
It is a shrub or small tree up to 8 m (26 ft) tall. The leaves are broadly elliptic and often arranged in pseudowhorls. They measure up to 10 cm (3.9 in) long and 5 cm (2.0 in) wide and have bluntly toothed edges. Flowers arise from the twigs or leaf axils in short fascicles, and are very small with four or five 2 mm (0.08 in) long petals. The fruit is an almost spherical capsule about 7 mm (0.28 in) diameter, containing one or two aril-covered seeds. [3] [4]
The plant was first described in 1984 by Australian botanist Laurence W. Jessup as Maytenus fasciculiflora, and published in an appendix to volume 22 of the book series Flora of Australia . [5] In 2011, American botanist Mark P. Simmons published a paper in which the Australian species of Maytenus were transferred to Denhamia, giving this plant its current binomial name. [6]
The species is found in northeastern Queensland, from Cape York Peninsula to the Atherton Tablelands. [3] [4]
As of November 2024 [update] , this species has been assessed to be of least concern by the International Union for Conservation of Nature (IUCN) and by the Queensland Government under its Nature Conservation Act. [7] [8]
Maytenus is a genus of flowering plants in the family Celastraceae. Members of the genus are distributed throughout Central and South America, Southeast Asia, Micronesia, and Australasia, the Indian Ocean and Africa. They grow in a very wide variety of climates, from tropical to subpolar. The traditional circumscription of Maytenus was paraphyletic, so many species have been transferred to Denhamia and Gymnosporia.
Euroschinus falcatus is a large tree in the mango and cashew family Anacardiaceae, found along almost the entire east coast of Australia from Cape York Peninsula to Jervis Bay. Common names include blush cudgerie and maiden's blush.
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.
Endiandra compressa, commonly known as whitebark or greenheart, is a rainforest tree in the Lauraceae family endemic to eastern Australia. It was first described in 1919 and has been given the conservation status of least concern.
Denhamia is a genus of plants within the family Celastraceae, with species in Australia, New Guinea, and New Caledonia. The species inhabit a variety of environments, from rainforest to semi-arid savanna. All species grow as shrubs or small trees up to 10 metres in height. 17 species are currently accepted. Based on a molecular and morphological analysis, the genus was enlarged in 2011 to include several Australian and Pacific island species formerly classified as Maytenus – Denhamia bilocularis, D. cunninghamii, D. cupularis, D. disperma, D. fasciculiflora, D. ferdinandii, D.fournieri, and D. silvestris.
Eupomatia barbata, also known as the small bolwarra, is a species of plant in the primitive family Eupomatiaceae. It is endemic to Queensland, Australia, and was first described in 2002.
Meiogyne cylindrocarpa, commonly known as fingersop or native apricot in Australia, is a small tree or shrub in the custard apple family Annonaceae, native to parts of tropical Asia and Australasia.
Baileyoxylon is a monotypic genus in the family Achariaceae. The sole described species is Baileyoxylon lanceolatum which is restricted to a very small part of the Wet Tropics of Queensland. It was described in the mid 20th century.
Irvingbaileya is a monotypic genus—that is, a genus that contains just one species—of flowering plants in the family Stemonuraceae. The sole species is Irvingbaileya australis, commonly known as buff beech or wax berry, a rainforest tree endemic to Queensland, Australia.
Pseuduvaria froggattii is a rare species of tree which is restricted to a very small part of northeastern Queensland, Australia. It is a member of the custard apple and soursop family Annonaceae, and was first described in 1887. Despite the small range its status considered to be least concern.
Myristica insipida, commonly known in Australia as Australian nutmeg, Queensland nutmeg or native nutmeg, is a small rainforest tree in the family Myristicaceae native to parts of Malesia, Papuasia and Australia. It is closely related to the commercially-important species of nutmeg, M. fragrans.
Euodia hylandii, commonly known as dwarf euodia, is a shrub or small tree in the citrus family Rutaceae. It is endemic to northeastern Queensland, Australia, and inhabits the understorey of well developed rainforest. The range extends from Kutini-Payamu National Park to the Daintree River, and from the sea level to 550 m (1,800 ft). It was first described by the American botanist Thomas Gordon Hartley in 2001. Crushed leaves are said to resemble the scent of ants in the Iridomyrmex group. The plant is named in honour of the botanist Bernard Hyland.
Buchanania mangoides, commonly known as plum tree, is a plant in the mango and cashew family Anacardiaceae native to Queensland, Australia. It was first described in 1869.
Hypsophila dielsiana is a small tree to 10 m (33 ft) in the family Celastraceae, found only in the Wet Tropics bioregion of Queensland, Australia. It was first described by the German botanist Ludwig Eduard Theodor Loesener in 1903.
Hypsophila halleyana is a small tree to 12 m (39 ft) in the family Celastraceae, found only in the Wet Tropics bioregion of Queensland, Australia. It was first described by the German-Australian botanist Ferdinand von Mueller in 1887.
Uvaria concava, commonly known as calabao, is a plant in the custard apple family Annonaceae found throughout tropical Asia, from India to the Northern Territory and Queensland in Australia. It is a tall vine with a stem diameter up to 5 cm.
Monoon michaelii is a plant in the custard apple family Annonaceae found only in a very small part of the Wet Tropics bioregion of Queensland, Australia. It was originally described as Polyalthia michaelii in 1915 and transferred to its current name in 2012.
Diploglottis bracteata, commonly known as Boonjee tamarind, is a plant in the lychee family Sapindaceae found only in the Wet Tropics bioregion of Queensland, Australia. It is a tree growing to about 25 m (82 ft) in height with a fluted trunk and distinctively large bracts of flowers. It was first described by the Dutch botanist Pieter Willem Leenhouts in 1978, and the common name refers to the area on the Atherton Tableland where the species occurs.
Xylopia maccreae, commonly known as orange jacket or MacCrea's xylopia, is a plant in the custard apple family Annonaceae found only in coastal areas of north and central Queensland, Australia. It is an evergreen tree up to 10 m (33 ft) tall with small buttresses, and young shoots covered in silky hairs. It was first described in 1868 as Melodorum maccreae by the botanist Ferdinand von Mueller, and transferred to the genus Xylopia in 1956 by Lindsay Stuart Smith. It is one of the food plants for the green-spotted triangle.
Symplocos puberula is a plant in the family Symplocaceae found in northeastern Queensland, Australia. It is a tree up to 25 m (82 ft) tall with pubescent new growth. The leaves are stiff, widest near the apex and tapered at the base (obovate), and they have a short "drip tip". They measure up to 15 cm (5.9 in) long and 6 cm (2.4 in) wide, and have 6–12 pairs of lateral veins either side of the midrib which curve forwards and connect to the next vein. The leaf edges are finely toothed in the distal half of the leaf blade.
