Adenanthos sericeus subsp. sericeus

Adenanthos sericeus subsp. sericeus, commonly known as coastal woollybush, [1] 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 (woolly bush), occurring mostly in the vicinity of King George Sound.

Description

As with the species in general, this subspecies grows as an upright, spreading shrub, or occasionally a small tree. It has erect branches that are covered in short hairs when young, but these are lost with age. Flowers are bright red, and the fruit is an oval-shaped achene about 5 mm (0.2 in) long. [2] [3]

The leaves of this subspecies are typically over 30 mm (1.2 in) long, and divided into many laciniae: average numbers range from 11 to 35, but individual leaves may have up to 50. In this way it differs from the other subspecies, A. sericeus subsp. sphalma, which has smaller leaves typically divided into around 6 laciniae, and rarely more than 12. [2] [3]

Discovery and naming

As the autonymic subspecies, the subspecies name necessarily encompasses the type specimen of the species, and is treated as having been automatically published upon publication of the species name by Jacques Labillardière in 1805. However the name did not come into use until Ernest Charles Nelson published A. sericeus subsp. sphalma in 1978.

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

A. oreophilus
A. cygnorum (2 subspecies)
A. meisneri
A. velutinus
A. filifolius
A. labillardierei
A. acanthophyllus

Distribution and habitat

Adenanthos sericeus subsp. sericeus occurs mostly around King George Sound, extending west as far as Torbay Inlet and east almost to Cape Riche; it sometimes occurs very close to the sea. It is calcifuge, occurring only in siliceous sands derived from weathered granite. Thus most populations are associated with granite monadnocks. Though its range is restricted, it is locally common and often dominant. [2] [3]

<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>Adenanthos obovatus</i> A shrub of the plant 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.

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.
