Hemichroa is a small genus of plants in the family Amaranthaceae containing three species. It is endemic to Australia.
Hemichroa is a genus of succulent, halophytic, perennial herbs and shrubs. They are found coastally as well as in salt marshes and around inland salt lakes. [1]
The halophiles, named after the Greek word for "salt-loving", are extremophiles that thrive in high salt concentrations. While most halophiles are classified into the domain Archaea, there are also bacterial halophiles and some eukaryotic species, such as the alga Dunaliella salina and fungus Wallemia ichthyophaga. Some well-known species give off a red color from carotenoid compounds, notably bacteriorhodopsin. Halophiles can be found in water bodies with salt concentration more than five times greater than that of the ocean, such as the Great Salt Lake in Utah, Owens Lake in California, the Dead Sea, and in evaporation ponds. They are theorized to be a possible candidate for extremophiles living in the salty subsurface water ocean of Jupiter's Europa and other similar moons.
Bass is a name shared by many species of fish. The term encompasses both freshwater and marine species, all belonging to the large order Perciformes, or perch-like fishes. The word bass comes from Middle English bars, meaning "perch".
Juncaceae is a family of flowering plants, commonly known as the rush family. It consists of 8 genera and about 464 known species of slow-growing, rhizomatous, herbaceous monocotyledonous plants that may superficially resemble grasses and sedges. They often grow on infertile soils in a wide range of moisture conditions. The best-known and largest genus is Juncus. Most of the Juncus species grow exclusively in wetland habitats. A few rushes, such as Juncus bufonius are annuals, but most are perennials.
The banded stilt is a nomadic wader of the stilt and avocet family, Recurvirostridae, native to Australia. It belongs to the monotypic genus Cladorhynchus. It gets its name from the red-brown breast band found on breeding adults, though this is mottled or entirely absent in non-breeding adults and juveniles. Its remaining plumage is pied and the eyes are dark brown. Nestling banded stilts have white down, unlike any other species of wader.
Myoporum is a genus of flowering plants in the figwort family, Scrophulariaceae. There are 30 species in the genus, eighteen of which are endemic to Australia although others are endemic to Pacific Islands, including New Zealand, and one is endemic to two Indian Ocean islands. They are shrubs or small trees with leaves that are arranged alternately and have white, occasionally pink flowers and a fruit that is a drupe.
Scirpus is a genus of grass-like species in the sedge family Cyperaceae many with the common names club-rush, wood club-rush or bulrush. They mostly inhabit wetlands and damp locations.
Avicennia is a genus of flowering plants currently placed in the bear's breeches family, Acanthaceae. It contains mangrove trees, which occur in the intertidal zones of estuarine areas and are characterized by its "pencil roots", which are aerial roots. It is commonly known as api api, which in the Malay language means "fires", a reference to the fact that fireflies often congregate on these trees. Species of Avicennia occur worldwide south of the Tropic of Cancer.
Tecticornia is a genus of succulent, salt tolerant plants largely endemic to Australia. Taxa in the genus are commonly referred to as samphires. In 2007, the genus Halosarcia, along with three other Australian genera was incorporated into the genus.
The flora of Australia comprises a vast assemblage of plant species estimated to over 20,000 vascular and 14,000 non-vascular plants, 250,000 species of fungi and over 3,000 lichens. The flora has strong affinities with the flora of Gondwana, and below the family level has a highly endemic angiosperm flora whose diversity was shaped by the effects of continental drift and climate change since the Cretaceous. Prominent features of the Australian flora are adaptations to aridity and fire which include scleromorphy and serotiny. These adaptations are common in species from the large and well-known families Proteaceae (Banksia), Myrtaceae, and Fabaceae.
Electracma is a genus of moths belonging to the family Tortricidae.
Adenanthos macropodianus, commonly known as gland flower, or Kangaroo Island gland flower, is a species of shrub in the family Proteaceae. It is endemic to Kangaroo Island in South Australia. First published as a variety of A. sericeus in 1870, it was promoted to species rank in 1978.
The Polycnemoideae are a small subfamily of plants in the family Amaranthaceae, representing a basal evolutionary lineage. The few relictual species are distributed in Eurasia and North Africa, North America, and Australia.
Hemichroa pentandra, commonly known as trailing hemichroa, trailing saltstar or trailing jointweed, is a prostrate perennial herb in the amaranth family. It is endemic to Australia. A succulent halophyte, it grows to about 10 cm in height and 30 cm wide. It has tiny, inconspicuous white flowers, surrounded by papery bracts, which grow in the angle between the stem and the 12 mm long leaves. It is found in coastal salt marshes and around salt lakes.
Hemichroa is a genus of sawflies in the family Tenthredinidae.
Hemichroa is the scientific name of two genera of organisms and may refer to:
Hakea oleifolia, commonly known as dungyn, or the olive-leaved hakea, is a shrub or tree of the family Proteacea and is endemic to an area along the south coast in the South West and Great Southern regions of Western Australia.
Hakea preissii, commonly known as the needle tree, needle bush and Christmas hakea, is a shrub or tree of the genus Hakea native to Western Australia. The Noongar name for the plant is Tanjinn.
Grevillea trachytheca, commonly known as vanilla grevillea or the rough-fruit grevillea is a shrub of the genus Grevillea native to an area in the Mid West and Gascoyne regions of Western Australia.
Gunniopsis is a genus of flowering plants in the iceplant family, Aizoaceae. These plants are found in areas of inland Australia.
The Raak Plain Boinka is a wilderness area in the state of Victoria, Australia. The boinka groundwater discharge complex is a shallow depression within a region of Mallee dune fields, and contains gypsum flats and salinas, pools of salty water that are mainly fed by groundwater. The distinctive flora of the boinka is largely intact and includes several threatened species.
