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.

Description

Common woollybush grows as a tall shrub up to three metres high. It has soft grey-green or grey-blue foliage, consisting of closely packed, small, hairy leaves on pliable, hairy stems. It is woolly both in appearance and feel, hence the common name. The leaves have nectaries at the tips; these attract ants, which play a role in the distribution of seed. The nectar filled cups are taken by the ants to their nests to be consumed, the seeds becoming inaccessible to birds, etc. Like most other Adenanthos species, but unusually for Proteaceae, the flowers of common woollybush are not large and showy, but are rather small, dull, and hidden within the foliage.

The stems of the plant are bored into by moths, leaving their eggs there; the larvae are in turn used by female wasps for their own eggs.

Taxonomy

A species of Adenanthos, a genus that is mostly restricted to the Southwest botanical province. Adenanthos cygnorum was first collected by the English botanist and plant-collector Allan Cunningham in 1818 at the Swan River, Western Australia. The specific name cygnorum, from the Latin cygnus meaning swan, refers to the type locality.

There are two subspecies: Adenanthos cygnorum subsp. cygnorum and Adenanthos cygnorum subsp. chamaephyton. The latter is a prostrate, mat-forming shrub; it is rare and poorly known, and some populations are under threat, but is not currently considered endangered.

Ecology

The brown honeyeater (Lichmera indistincta) has been observed feeding at the flowers of A. cygnorum. [1]

It is highly susceptible to Phytophthora cinnamomi dieback. [2]

<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.

<i>Banksia telmatiaea</i> Australian shrub that grows in marshes and swamps

Banksia telmatiaea, commonly known as swamp fox banksia or rarely marsh banksia, is a shrub that grows in marshes and swamps along the lower west coast of Australia. It grows as an upright bush up to 2 metres tall, with narrow leaves and a pale brown flower spike, which can produce profuse quantities of nectar. First collected in the 1840s, it was not published as a separate species until 1981; as with several other similar species it was previously included in B. sphaerocarpa.

<i>Banksia violacea</i> Species of plant

Banksia violacea, commonly known as violet banksia, is a species of shrub or tree in the plant genus Banksia. It generally grows as a small shrub to 1.5 m (5 ft) high with fine narrow leaves, and is best known for its unusually coloured dark purple-violet inflorescences. The colour of the inflorescences, short leaves, and flattened follicles which are sticky when young, help identify this species from others in the field. It is found in low shrubland in southern regions of Western Australia from Esperance in the east to Narrogin in the west, growing exclusively in sandy soils.

Banksia montana, commonly known as the Stirling Range dryandra, is a species of shrub that is endemic to the Stirling Range in Western Australia. It has hairy stems, linear pinnatisect leaves with twisted, triangular lobes, yellow flowers in heads of about sixty and reddish-brown follicles.

<i>Adenanthos sericeus</i> Species of shrub native to the south coast of Western Australia

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.

<i>Adenanthos obovatus</i> Shrub of the family Proteaceae, endemic to southwest Australia

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.

<i>Adenanthos terminalis</i> Species of shrub in the family Proteaceae found in south eastern regions of Australia

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.

Nelsons taxonomic arrangement of <i>Adenanthos</i> First modern arrangement of the plant genus

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.
