Adenanthos sect. Eurylaema is a taxonomic section of the flowering plant genus Adenanthos (Proteaceae). It comprises four species, all of which are endemic to southwest Western Australia.
The section is characterised by flowers in which the stamen on the back of the style is sterile, and the style end is broad and flattened. [1]
The section was first described and published by George Bentham in the 1870 fifth volume of his landmark work Flora Australiensis . Bentham listed several diagnostic characters for the species including the bent and dilated perianth-tube; the sterility of one of the four anthers; the broad, flattened style-end; flat, entire leaves; and axillary flowers. He did not give an etymology for the epithet Eurylaema, [2] but Ernest Charles Nelson states that it comes from eurys ("broad") and laemos ("neck"), referring to the dilated perianth-tube. [3] Bentham also did not designate a type species for the section; Nelson has since defined A. obovatus to be its lectotype. [3]
When published by Bentham in 1870, A. sect. Eurylaema comprised only two species, A. barbigera (now A. barbiger ) and A. obovata (now A. obovatus). [2] Four years later, Ferdinand von Mueller published A. detmoldii , referring it to this section. [4]
In 1978, Nelson published a comprehensive taxonomic revision of Adenanthos. He retained A. sect. Eurylaema, making no change to its circumscription, but discarded many of Bentham's diagnostic characters, retaining only the sterile anther and the shape of the style-end. [3] The following year, Nelson formally described and named A. × pamela, a naturally occurring hybrid of A. detmoldii and A. obovatus. Despite both parents belonging to this section, initially he did not assign the hybrid to it; he did so, however, in his 1995 treatment of Adenanthos for the Flora of Australia series of monographs. [1]
The placement and circumscription of A. sect. Eurylaema in Nelson's arrangement of Adenanthos may be summarised as follows: [1]
All four species in A. sect. Eurylaema are endemic to southwest Western Australia. [1]
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.
Banksia ser. Cyrtostylis is a taxonomic series within the plant genus Banksia. First published at sectional rank by George Bentham in 1870, it was demoted to a series by Alex George in 1981. The name has had three circumscriptions.
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 cacomorphus is a small shrub in the family Proteaceae. It is found in southwest Western Australia.
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 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.
