Adenanthos cacomorphus is a small shrub in the family Proteaceae. It is found in southwest Western Australia.
Adenanthos cacomorphus grows as a small lignotuberous shrub up to one metre (3 ft) high. The soft and hairy leaves are more or less triangular in shape with 3 to 5 (occasionally up to 7) apical lobes. The single pink flowers consist of a bright pink perianth about 2.5 cm (1 in) long, and a style up to 3.5 cm (1.6 in) long. They are seen over the warmer months from November to March. [1]
It resembles its close relative A. cuneatus , but has more deeply lobed leaves and a different flower colour. [1]
Botanical specimens of this species had been collected as far back as 1969, but the species was not published until 1978, when Irish botanist Ernest Charles Nelson issued a thorough revision of Adenanthos. He published this species based on a type specimen collected by Kenneth Newbey in Fitzgerald River National Park in 1974. Studies of the species' pollen prior to publication had shown that some pollen grains were "grossly misshapen", lacking their usual triangular shape, and having more than the usual three pores. He therefore chose the specific epithet cacomorpha from the Ancient Greek kakos ("ugly"), and morphe ("form"). [2]
Nelson followed George Bentham in dividing Adenanthos into two sections, placing A. cacomorphus into A. sect. Adenanthos because its perianth tube is straight and not swollen above the middle. He further divided the section into two subsections, with A. cacomorpha placed into A. subsect. Adenanthos for reasons including the length of its perianth. [2] However Nelson discarded his own subsections in his 1995 treatment of Adenanthos for the Flora of Australia series of monographs. By this time, the ICBN had issued a ruling that all genera ending in -anthos must be treated as having masculine gender, so A. cacomorpha became A. cacomorphus. [1]
The placement of A. cacomorphus in Nelson's arrangement of Adenanthos may be summarised as follows: [1]
A. cacomorphus has many characteristics shared with or intermediate between two species with which is co-occurs, A. cuneatus and A. flavidiflorus . There are considered its closest relatives, and it is possible that A. cacomorphus originated as a hybrid between them. [1] [2]
It is endemic to southern Western Australia, restricted to the Fitzgerald River National Park and surrounds. Adenanthos cacomorphus is found in kwongan growing on sand or sandy gravel. [1]
It is classified as Priority Two - Poorly Known on the Western Australia Department of Environment and Conservation's Declared Rare and Priority Flora List. [3] That is, it is a taxon which is known from few populations, at least some of which are not believed to be under immediate threat. [4]
It is not known in cultivation, as it is fairly rare, and offers no advantages over the similar and more common A. cuneata. [5]
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 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.
Ernest Charles Nelson's taxonomic arrangement of Adenanthos was the first modern-day arrangement of that plant genus. First published in his 1978 Brunonia article "A taxonomic revision of the genus Adenanthos (Proteaceae)", it superseded the arrangement of George Bentham, which had stood for over a hundred years. It was updated by Nelson in his 1995 treatment for the Flora of Australia series of monographs.
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 detmoldii, commonly known as Scott River jugflower or yellow jugflower, is a species of shrub in the family Proteaceae. It is endemic to the south-west of 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.
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 × pamela is a naturally occurring hybrid of A. detmoldii and A. obovatus in Western Australia.
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.
George Bentham's taxonomic arrangement of Adenanthos was the first comprehensive taxonomic arrangement of that plant genus. It was published in 1870 in his landmark flora of Australia, Flora Australiensis. It would stand for over a hundred years before being superseded by the 1978 arrangement of Ernest Charles Nelson.
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.
