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 one 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 .

Description

Adenanthos barbiger grows as an upright or spreading small shrub, up to 1 m (3 ft) in height, often with many stems arising from an underground lignotuber. Young branches are covered in hairs, but these are lost with age. The leaves are long and thin (up to 8 cm long but only about 7 mm wide), oval-shaped, and lack a petiole. The flowers, which appear between August and December, consist of a bright red tubular perianth about 25 mm long, covered in silky white hairs; and a style about 40 mm long. [2] [3]

Taxonomy

This species was first published under the name Adenanthos barbigera by John Lindley in his 1839 A Sketch of the Vegetation of the Swan River Colony . [4] The specific epithet is from the Latin barba ("beard"), in reference to the white hairs on the perianth. [5]

Lindley did not specify a type specimen, but his herbarium contains a sheet designated as the type for the species. This sheet contains two specimens. One was collected by James Drummond, but both the date and the location of the collection is uncertain. The other is labelled "Vasse River... Mrs. Capt. Molloy, 1839." These were most probably collected from Busselton in 1837 by John Molloy, not his wife Georgiana, who didn't visit Busselton until 1839. Georgiana Molloy sent them to James Mangles in London in 1838; they arrived early in 1839, and were immediately sent on to Lindley. [2]

In 1870, George Bentham published the first infrageneric arrangement of Adenanthos in Volume 5 of his landmark Flora Australiensis . Bentham divided the genus into two sections, placing A. barbigera in A. sect. Eurylaema, defined as containing those species with perianth tubes that are curved and swollen above the middle. [6]

In 1921, Carl Hansen Ostenfeld published Adenanthos intermedia (now A. intermedius), based on specimens found at Yallingup with leaf shape intermediate between those of A. barbiger and those of A. obovata . This was rejected in 1978 by Ernest Charles Nelson, who argued that leaf shape is inappropriate grounds for erecting a new species in this context, and that, in terms of systematically important characteristics, A. intermedius is indistinguishable from A. barbiger. He therefore synonymized A. intermedius with A. barbiger, but noted the possibility that A. intermedius is of hybrid origin. [2]

A. barbigera was retained in A. sect. Eurylaema in Ernest Charles Nelson's 1978 revision of Adenanthos, [2] and again in his 1995 treatment of the genus for the Flora of Australia series. By this time, the ICBN had issued a ruling that all genera ending in -anthos must be treated as having masculine gender. At least one publication subsequently referred to it as Adenanthos barbigerus, [5] but Nelson's 1995 treatment called it Adenanthos barbiger, [3] and this is now the accepted name. [7]

The placement of A. barbiger in Nelson's arrangement of Adenanthos may be summarised as follows: [3]

Adenanthos
A. sect. Eurylaema
A. detmoldii
A. barbiger
A. obovatus
A. × pamela
A. sect. Adenanthos (29 species, 8 subspecies)

Distribution and habitat

Adenanthos barbiger occurs between the west coast of Western Australia and the Darling Range, from Toodyay in the north, south to Manjimup. It is common in the north and south of its range, but appears to be quite uncommon in central parts. It mostly occurs in jarrah forest, but is sometimes found in more open habitats. [2] It survives in a range of soils. [8]

It is highly susceptible to Phytophthora cinnamomi dieback. [9]

Cultivation

This species is known to have been introduced into cultivation in Great Britain in 1845, but it is now not much cultivated. It is a good bird attractor and tolerates frost. Propagation is from cuttings; new shoots can be removed from the lignotuber and will root well under mist. The species requires a well-drained soil in full or half sun. [5]

<i>Adenanthos</i> Genus of Australian native shrubs in the flowering plant family Proteaceae

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 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.
