Adenanthos ellipticus, commonly known as the oval-leaf adenanthos, is a flowering plant from the family Proteaceae that is endemic to Western Australia where it is considered to be Declared Rare Flora. [1]
Adenanthos ellipticus grows as an open spreading shrub to 3 m (10 ft) high and 4 m (13 ft) wide. [2] The leaves are 2–5 centimetres (0.79–1.97 in) long by 5–15 millimetres (0.20–0.59 in) wide, while the orange or reddish-pink coloured flowers are 2.5 centimetres (0.98 in) long. [3]
Alex George described Adenanthos ellipticus in 1974, the species name derived from the Latin adjective ellipticus and referring to the shape of the leaves. It had been collected much earlier, in 1931 by W.E.Blackall. He published the name A. cuneata var. integra in 1954 but did not write a description so the name is invalid. [2] It is classified in the section Adenanthos within the genus of the same name. [4]
Adenanthos ellipticus is found only in Fitzgerald River National Park, where it occurs in three populations occupying an area of less than 0.31 square kilometres (77 acres). [3] It grows in quartzite-derived siliceous sand on rocky hillsides. [1] It is found in association with coastal jugflower ( Adenanthos cuneatus ) and veined adenanthos ( A. venosus ), but generally grows higher up slopes than those species. [3]
Adenanthos ellipticus is killed by bushfire and regenerates from seed afterwards. Fires at short intervals threaten to eradicate it. [3] It is also highly sensitive to dieback ( Phytophthora cinnamomi ). [3]
The Commonwealth and Western Australian Governments have classified Adenanthos ellipticus as vulnerable under the Environment Protection and Biodiversity Conservation Act 1999 in 2008 and Wildlife Conservation Act 1950 (Western Australia) in November 2012 respectively. [5]
Adenanthos ellipticus is unknown in cultivation, and has little horticultural potential, especially compared with the smaller, more compact A. cuneatus. It would likely need frequent pruning to maintain an attractive appearance. [2]
Adenanthos is a genus of Australian native shrubs in the flowering plant family Proteaceae. Variable in habit and leaf shape, it is the only genus in the family where solitary flowers are the norm. It was discovered in 1791, and formally published by Jacques Labillardière in 1805. The type species is Adenanthos cuneatus, and 33 species are recognised. The genus is placed in subfamily Proteoideae, and is held to be most closely related to several South African genera.
Adenanthos cygnorum, commonly known as common woollybush or just woollybush, is a tall shrub in the family Proteaceae. It is endemic to Western Australia, commonly occurring in the south west of the State from north of Geraldton south to Kojonup. It is very common on road verges and in disturbed areas of Perth.
Banksia anatona, commonly known as the cactus dryandra, is a flowering plant in the family, Proteaceae and is endemic to Western Australia. It is a tall, spindly shrub with unusually large fruiting follicles. It is only known from a single location and has been classified as Critically Endangered nationally under the Environment Protection and Biodiversity Conservation Act 1999. The only known population is in danger of extinction from dieback disease.
Adenanthos sericeus, commonly known as woolly bush, is a shrub native to the south coast of Western Australia. It has bright red but small and obscure flowers, and very soft, deeply divided, hairy leaves.
Adenanthos obovatus, commonly known as basket flower, or, jugflower, is a shrub of the plant family Proteaceae endemic to Southwest Australia. Described by French naturalist Jacques Labillardière in 1805, it had first been collected by Archibald Menzies in 1791. Within the genus Adenanthos, it lies in the section Eurylaema and is most closely related to A. barbiger. A. obovatus has hybridized with A. detmoldii to produce the hybrid A. × pamela. Several common names allude to the prominent red flowers of the species. It grows as a many-stemmed spreading bush up to 1 m (3.3 ft) high, and about 1.5 m (4.9 ft) across, with fine bright green foliage. Made up of single red flowers, the inflorescences appear from April to December, and peak in spring.
Adenanthos terminalis, commonly known as gland flower, yellow gland flower or adenanthos, is a one metre tall shrub in the family Proteaceae. It is found in south eastern regions of Australia, in the states of South Australia and Victoria, and is the most widespread of the two Adenanthos species occurring outside of Western Australia.
Adenanthos cuneatus, also known as coastal jugflower, flame bush, bridle bush and sweat bush, is a shrub of the family Proteaceae, native to the south coast of Western Australia. The French naturalist Jacques Labillardière originally described it in 1805. Within the genus Adenanthos, it lies in the section Adenanthos and is most closely related to A. stictus. A. cuneatus has hybridized with four other species of Adenanthos. Growing to 2 m high and wide, it is erect to prostrate in habit, with wedge-shaped lobed leaves covered in fine silvery hair. The single red flowers are insignificant, and appear all year, though especially in late spring. The reddish new growth occurs over the summer.
Adenanthos macropodianus, commonly known as gland flower, or Kangaroo Island gland flower, is a species of shrub in the family Proteaceae. It is endemic to Kangaroo Island in South Australia. First published as a variety of A. sericeus in 1870, it was promoted to species rank in 1978.
Adenanthos cacomorphus is a small shrub in the family Proteaceae. It is found in southwest Western Australia.
Adenanthos ileticos is a species of shrub in the family Proteaceae. It has roughly triangular, lobed leaves, and pale pink-red and cream, inconspicuous flowers. A rare species, it is known only from a single location in the south-west of Western Australia. It was discovered in 1968, and immediately brought into cultivation, but it would not be formally published and named until a decade later.
Adenanthos barbiger, the hairy jugflower or hairy glandflower, is a species of shrub in the family Proteaceae. It is endemic to the south-west of Western Australia. It usually grows to 1 metre high, and has bright red flowers that appear mostly between August and December. The species was first formally described in 1839 by English botanist John Lindley in A sketch of the vegetation of the Swan River colony.
Adenanthos × cunninghamii, commonly known as woollybush, Albany woollybush or prostrate woollybush, is a hybrid shrub in the family Proteaceae. It is endemic to the south-west of Western Australia. The Noongar peoples know the plant as boyur.
Adenanthos dobagii, commonly known as Fitzgerald woollybush, is a shrub in the family Proteaceae. It grows to a mere 50 cm high, with crowded small silvery leaves and insignificant pink or cream flowers. It occurs only in southwestern Australia, where it is found in Fitzgerald River National Park on the south coast.
Adenanthos eyrei is a species of shrub in the family Proteaceae. Restricted to a single cliff-top dune system on the remote south coast of Western Australia, it is listed as rare and endangered. It was discovered by E. Charles Nelson in 1973, and formally described and named in 1978.
Adenanthos sect. Adenanthos is a taxonomic section of the flowering plant genus Adenanthos (Proteaceae). It comprises 29 species. The centre of diversity is southwest Western Australia, with two species extending into South Australia and western Victoria.
Adenanthos glabrescens is a species of small shrub endemic to the Ravensthorpe area in southwest Western Australia. First published in 1978, there are two subspecies.
Adenanthos labillardierei is a species of erect shrub endemic to the slopes of the Barren Ranges in the Fitzgerald River National Park in southwest Western Australia.
Adenanthos oreophilus, commonly known as woollybush, is a species of tall shrub endemic to southwest Western Australia. It is closely related to the better known A. sericeus, and was only classified as a species distinct from the latter in 1978 by Irish botanist E. Charles Nelson.
Adenanthos sericeus subsp. sericeus, commonly known as coastal woollybush, is a shrub native to the south coast of Western Australia. It has bright red but small and obscure flowers, and very soft, deeply divided, hairy leaves. It is the western subspecies of Adenanthos sericeus, occurring mostly in the vicinity of King George Sound.
