Adenanthos detmoldii, commonly known as Scott River jugflower or yellow jugflower, [3] is a species of shrub in the family Proteaceae. It is endemic to the south-west of Western Australia.
It grows as an erect shrub to 4 m (13 ft) in height, with hairy branches and long, narrow leaves up to 80 mm length and about 5 mm wide. The flowers, which appear between August and November, consist of a tubular perianth about 25 mm long, and a style about 40 mm long. The perianth is yellow with an orange throat that becomes brown following pollination. [4]
The type specimen of A. detmoldii was collected from the vicinity of the Blackwood River around 1870, [5] and sent to Ferdinand von Mueller who published the species in Volume 8 of his Fragmenta Phytographiae Australiae in 1874. The original type specimen cites "Blackwood-River; J. Forrest", [6] and this has sometimes been interpreted as referring to John Forrest, [7] but John Forrest's brother James is known to have "achieved some repute by making botanical collections of the flora of the Blackwood district for Baron von Mueller", [8] and an isotype lodged at the Botanical Garden in Berlin has been labelled by Ludwig Diels "Blackwood River leg. Jas. Forrest". [9]
Mueller assigned the species to A. sect. Eurylaema, [6] defined as containing those species with perianth tubes that are curved and swollen above the middle. [10] The specific epithet detmoldii was said to be in honour of his friend William Detmold. [6]
A. detmoldii was retained in A. sect. Eurylaema in Ernest Charles Nelson's 1978 revision of Adenanthos, [5] and again in his 1995 treatment of the genus for the Flora of Australia series. The placement of A. detmoldii in Nelson's arrangement of Adenanthos may be summarised as follows: [4]
This species frequently hybridises with Adenanthos obovatus ; the resulting hybrids are known as Adenanthos × pamela . [4]
A. detmoldii is restricted to the vicinity of the Scott and Blackwood Rivers east of Augusta, Western Australia. Unusually for Adenanthos species, it favours damp winter-wet, sandy flats, where it co-occurs with Banksia ser. Dryandra species, Grevillea species, grasses and sedges. It is often the most abundant shrub where it occurs. [5]
It is classified as Priority Four - Rare on the Western Australian Department of Environment and Conservation's Declared Rare and Priority Flora List. [1] That is, it is a taxon which, though rare, does not appear to be threatened. [11] It is said to be now largely confined to road verges because most of its range has been cleared for agriculture, [4] though in 1978 Nelson still held out some hope that "[i]t may be common in wet swamp areas that are not accessible and have not been drained." [5]
It is highly susceptible to Phytophthora cinnamomi dieback. [12]
The species prefers well-drained, light soils in full sun to part shade, [13] though, as its natural occurrence in winter-wet areas would suggest, it is hardier to poor drainage than most Adenanthos species. [3] Naturally a dry-summer plant, it performs unexpectedly well in areas with wet or humid summers, though it is vulnerable to grey mould in such climates. Propagation is by cuttings of semi-mature growth. [13]
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 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 meisneri, commonly known as prostrate woollybush, is a species of shrub in the family Proteaceae. It is endemic to the south-west of Western Australia.
Adenanthos pungens, the spiky adenanthos, is a species of shrub in the family Proteaceae. It is endemic to the south-west of Western Australia.
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 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.
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 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.
