Eutaxia diffusa, commonly known as spreading eutaxia, is a shrub species in the family Fabaceae. The species is endemic to Australia.
Plants grow to between 0.5 and 1 metre high with a similar spread. The small, grey green, obovate (or narrow obovate) leaves are lighter coloured beneath and have an acute tip. The single pea flowers have orange-yellow keels, yellow wings and a yellow standard that may have red markings. These are produced between August and October in the species' native range and are followed in November by ellipsoid fruits that are around 5.5 mm long and 4 mm wide. [1]
Eutaxia diffusa was named by Victorian Government Botanist Ferdinand von Mueller in 1858, when his original description was published in the first volume of his Fragmenta Phytographiae Australiae . The specific epithet derives from the Latin word diffusa, meaning spreading widely or loosely. It is thought to be a reference to either its spreading habit or relatively uncrowded leaves. [1]
The species was reclassified as a subspecies of Eutaxia microphylla in 1957 before Mueller's original name was reinstated in 2010. [2]
Eutaxia diffusa has a range that extends from Inglewood in Queensland southwards through New South Wales, where it is recorded in mallee communities, and in to south-western Victoria and westward across to South Australia. Associated tree species include Eucalyptus behriana , Acacia trineura and Melaleuca lanceolata . [1] [3]
Caterpillars of the Fringed Blue butterfly feed on this species. [4]
Eutaxia is a genus of the family Fabaceae. They are native to Australia. Most are endemic to the Southwest Botanical Province of Western Australia, but a few are distributed throughout mainland Australia. The chromosome number of Eutaxia species is typically 2n = 14 or 16.
Banksia canei, commonly known as the mountain banksia, is a species of shrub that is endemic to southeastern Australia. It is generally encountered as a many-branched shrub that grows up to 3 m (10 ft) high, with narrow leaves and the yellow inflorescences appearing from late summer to early winter. The old flowers fall off the spikes and up to 150 finely furred follicles develop, which remain closed until burnt in a bushfire. Each follicle bears two winged seeds. Response to fire is poorly known, although it is thought to regenerate by seed. Birds such as the yellow-tufted honeyeater and various insects forage among the flower spikes. It is frost tolerant in cultivation, but copes less well with aridity or humidity and is often short-lived in gardens. One cultivar, Banksia 'Celia Rosser', was registered in 1978, but has subsequently vanished.
Banksia marginata, commonly known as the silver banksia, is a species of tree or woody shrub in the plant genus Banksia found throughout much of southeastern Australia. It ranges from the Eyre Peninsula in South Australia to north of Armidale, New South Wales, and across Tasmania and the islands of Bass Strait. It grows in various habitats, including Eucalyptus forest, scrub, heathland and moorland. Banksia marginata varies widely in habit, ranging from a 20-centimetre (7.9 in) shrub to a 12-metre (40 ft) tree. The narrow leaves are linear and the yellow inflorescences occur from late summer to early winter. The flower spikes fade to brown and then grey and develop woody follicles bearing the winged seeds. Originally described by Antonio José Cavanilles in 1800, further collections of B. marginata were designated as several separate species by Robert Brown in 1810. However, all were reclassified as a single species by George Bentham in 1870. No distinct subspecies have been recognised by Banksia expert Alex George, who nonetheless concedes that further work is needed.
Eutaxia myrtifolia, also commonly known as egg and bacon plant or bush pea, is shrub species in the family Fabaceae. It is endemic to Western Australia. Plants may be prostrate or up to 2 metres high. Yellow and red flowers are produced throughout the year in the species' native range. It occurs in woodland, shrubland and heath in the coastal region between Cape Naturaliste and Cape Arid.
Grevillea victoriae, also known as royal grevillea or mountain grevillea, is a species of flowering plant in the family Proteaceae and is endemic to mountainous regions of south-eastern continental Australia. It is an erect to spreading shrub with elliptic to lance-shaped leaves, and pendulous clusters of red to orange flowers.
Acacia pravissima, commonly known as Ovens wattle, Oven wattle, wedge-leaved wattle and Tumut wattle, is a species of flowering plant in the legume family Fabaceae. It is an evergreen shrub native to Victoria, the South West Slopes and Southern Tablelands of New South Wales, Australia.
Orites lancifolius, commonly known as alpine orites, is a shrub in the family Proteaceae. It is endemic to south-eastern Australia. The species has a spreading habit and may be a prostrate or up to 2 metres high. The leaves are 1 to 3 cm long, and 5 to 12 mm wide. White to pale yellow flowers appear between December and January in its native range. The species was first formally described in 1855 by botanist Ferdinand von Mueller from plant material that he collected "on the rocky summits of the Australian Alps ".
Podolobium alpestre, commonly known as alpine shaggy-pea, is a flowering plant in the family Fabaceae and is endemic to south-eastern Australia. It has oblong to egg-shaped leaves and yellow to orange pea-like flowers with red markings.
Acacia decora is a plant native to eastern Australia. Common names include the western silver wattle and the showy wattle. The species name refers to the plant's decorative qualities.
Acacia howittii, commonly known as sticky wattle or Howitt's wattle, is a tree species that is endemic to Victoria, Australia.
Eutaxia microphylla, also known as common eutaxia, is a shrub species in the family Fabaceae. The species is endemic to Australia.
Bossiaea prostrata, commonly known as creeping bossiaea, is a prostrate understory shrub in the pea family, Fabaceae. It is a widespread species with orange-yellow flowers, purple-brown keels and trailing branches.
Grevillea stenobotrya is a shrub or small tree in the family Proteaceae that is endemic to arid regions of Australia. Common names include rattle-pod grevillea, sandhill grevillea, sandhill oak and sandhill spider flower.
Eucalyptus gracilis, commonly known as yorrell, snap and rattle, red mallee, white mallee or kong mallee, is a species of mallee or small tree endemic to Australia, where it is found in south-western New South Wales, Victoria, South Australia and Western Australia. It has smooth white bark, usually with rough, fibrous or flaky bark on the lower stems, linear to narrow lance-shaped adult leaves, flower buds in group of between seven and eleven and cup-shaped, cylindrical or barrel-shaped fruit.
