Tetratheca hirsuta, commonly known as black-eyed Susan, is a small shrub in the family Elaeocarpaceae. Endemic to the south-west of Western Australia, it is not related to other plants known as black-eyed Susan around the world.
Tetratheca hirsuta has an erect, climbing habit, growing to between 0.1 and 0.9 (4–36 in) metres high. It has a woody rootstock from which arise multiple rough stems which are hairy at their upper ends. The green hairy leaves are arranged alternately, oppositely or in whorls and measure 0.5–2.5 cm (0.2–1 in) by 0.5–1 cm (0.2–0.4 in). Pink flowers appear between July and December in the species' native range. They appear on stalks around 3 cm (1.2 in) in length and are 2 cm (0.8 in) in diameter. They have five deep pink or purple-tinted petals. [1] [2]
The species was first formally described by English botanist John Lindley in 1839 in A sketch of the vegetation of the Swan River colony [3] The specific name hirsuta is Latin "hairy". [2] The genus name is derived from the Ancient Greek tetra "four", and theke "sac, box" and relates to the four-celled anthers. [2]
Tetratheca hirsuta is found on lateritic gravelly soils in open woodland and heath in southwestern Western Australia, in the Darling, Avon and western Eyre districts. [2]
First cultivated in England in 1843 (as T. rubriseta), Tetratheca hirsuta is rarely cultivated but has horticultural potential, for rockeries. It prefers acidic soils and sunny or part-shaded aspect. Pruning stems to just above ground level can rejuvenate the plant. [2]
Leucanthemum vulgare, commonly known as the ox-eye daisy, oxeye daisy, dog daisy, marguerite and other common names, is a widespread flowering plant native to Europe and the temperate regions of Asia, and an introduced plant to North America, Australia and New Zealand.
Banksia serrata, commonly known as the saw banksia, the old man banksia, the saw-tooth banksia or the red honeysuckle and as wiriyagan by the Cadigal people, is a species of woody shrub or tree of the genus Banksia, in the family Proteaceae. Native to the east coast of Australia, it is found from Queensland to Victoria with outlying populations on Tasmania and Flinders Island. Commonly growing as a gnarled tree up to 16 m (50 ft) in height, it can be much smaller in more exposed areas. This Banksia species has wrinkled grey bark, shiny dark green serrated leaves and large yellow or greyish-yellow flower spikes appearing over summer. The flower spikes, or inflorescences, turn grey as they age and pollinated flowers develop into large, grey, woody seed pods called follicles.
Cardamine hirsuta, commonly called hairy bittercress, is an annual or biennial species of plant in the family Brassicaceae, and is edible as a salad green. It is common in moist areas around the world.
Banksia media, the southern plains banksia or golden stalk banksia, is a species of flowering plant in the family Proteaceae. An evergreen shrub, it occurs on the south coast of Western Australia between Albany and Israelite Bay, where it is a common plant. A many-branched bush with wedge-shaped serrated leaves and large golden-yellow flower spikes, known as inflorescences, it grows up to 10 metres (30 ft) high.
Banksia scabrella, commonly known as the Burma Road banksia, is a species of woody shrub in the genus Banksia. It is classified in the series Abietinae, a group of several species of shrubs with small round or oval inflorescences. It occurs in a number of isolated populations south of Geraldton, Western Australia, with the largest population being south and east of Mount Adams. Found on sandy soils in heathland or shrubland, it grows to 2 m (7 ft) high and 3 m (10 ft) across with fine needle-like leaves. Appearing in spring and summer, the inflorescences are round to oval in shape and tan to cream with purple styles. Banksia scabrella is killed by fire and regenerates by seed.
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.
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.
Tetratheca is a genus of around 50 to 60 species of shrubs endemic to Australia. It is classified in the botanical family Elaeocarpaceae, now known to encompass the family Tremandraceae, which the genus originally belonged to. It occurs throughout extratropical Australia, and has been recorded in every mainland state except the Northern Territory.
Banksia hirta is a species of shrub that is endemic to Western Australia. It has hairy stems, deeply serrated leaves, pale yellow flowers in heads of about one hundred and shining follicles. It is restricted to the Stirling Range National Park.
Verticordia brownii, commonly known as pink brownii or pink cauliflower is a flowering plant in the myrtle family, Myrtaceae, and is endemic to the south-west of Western Australia. It has small, neatly arranged, oval leaves and heads of pale pink to magenta or white flowers. It was one of the first verticordias to be collected, although it was not initially known by that name. The collection was made by Robert Brown on the Bass and Flinders circumnavigation of the Australian mainland on HMS Investigator.
Verticordia habrantha, commonly known as hidden featherflower, is a flowering plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. It is a slender shrub with short, leafy side-branches and long flowering stems with rounded heads of mostly white flowers. Its hairy sepals are mostly hidden by the round, unfringed petals, and as a result, the plant looks like shrubs in the genus Chamelaucium, to which it is closely related.
Hakea amplexicaulis, commonly known as prickly hakea, is a shrub endemic to south west Western Australia. An attractive small shrub with unusual stem clasping, sharply serrated foliage and a profusion of sweetly scented variable coloured flowers from late winter to spring.
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.
Lomatia hirsuta, known as radal, is a tree native to Argentina, Chile, and Peru.
Astroloma pinifolium, commonly known as pine heath, is small prostrate shrub or groundcover in the family Ericaceae endemic to eastern Australia.
Tetratheca thymifolia, commonly known as black-eyed Susan or thyme pink-bells, is a small shrub in the family Elaeocarpaceae found in southeastern Australia.
Tetratheca juncea, commonly known as black-eyed Susan or pink bells, is a small shrub in the family Elaeocarpaceae. Endemic to New South Wales, it is not related to other plants known as Black-eyed Susan around the world.
Hakea erecta is a shrub in the family Proteaceae and is endemic to Western Australia. It is a dense rounded shrub with linear twisted leaves and up to 24 pink or white fragrant flowers appearing in leaf axils in spring.
Tetratheca pilosa is a flowering plant in the family Elaeocarpaceae, endemic to Australia. It is a small shrub found in dry sclerophyll forests, open heathlands and woodlands of Australia. It was first recorded in 1805 by French botanist Jacques Labillardière.
Goodenia hirsuta is a species of flowering plant in the family Goodeniaceae and is endemic to northern Australia. It is a hairy, prostrate to low-lying perennial herb with narrow egg-shaped leaves at the base of the plant, racemes of hairy yellow flowers and oval to elliptic fruit.
