Spencer Gulf
The Spencer Gulf is the westernmost and larger of two large inlets (the other being Gulf St Vincent) on the southern coast of Australia, in the state of South Australia, facing the Great Australian Bight. It spans from the Cape Catastrophe and Eyre Peninsula in the west to Cape Spencer and Yorke Peninsula in the east.

Little Penguin
The little penguin (''Eudyptula minor'') is a species of penguin from New Zealand. They are commonly known as little blue penguins or blue penguins owing to their slate-blue plumage and are also known by their Māori name . The Australian little penguin (''Eudyptula novaehollandiae'') from Australia and the Otago region of New Zealand is considered a separate species by a 2016 study and a 2019 study. Taxonomy The little penguin was first described by German naturalist Johann Reinhold Forster in 1781. Several subspecies are known, but a precise classification of these is still a matter of dispute. The holotypes of the subspecies ''E. m. variabilis'' and ''Eudyptula minor chathamensis'' are in the collection of the Museum of New Zealand Te Papa Tongarewa. The white-flippered penguin (''E. m. albosignata'' or ''E. m. minor morpha albosignata'') is currently considered by most taxonomists to be a colour morph or subspecies of ''Eudyptula minor.'' In 2008, Shirihai treated th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bower Spinach
''Tetragonia implexicoma'', commonly known as bower spinach, is a species of plant in the Aizoaceae, or ice-plant family.

It occupies a variety of habitats from sand and shingle beaches through coastal woodland, shrubland and grassland, and as exposed, salt-pruned vegetation on cliffs and stacks. It may also be found well inland, in farmland where it is grown in barberry hedges, or on calcareous sandstone or limestone Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime.

Calcrete
Caliche () is a sedimentary rock, a hardened natural cement of calcium carbonate that binds other materials—such as gravel, sand, clay, and silt. It occurs worldwide, in aridisol and mollisol soil orders—generally in arid or semiarid regions, including in central and western Australia, in the Kalahari Desert, in the High Plains of the western United States, in the Sonoran Desert, Chihuahuan Desert and Mojave Desert of North America, and in eastern Saudi Arabia at Al-Hasa. Caliche is also known as calcrete or kankar (in India). It belongs to the duricrusts. The term ''caliche'' is Spanish and is originally from the Latin ''calx'', meaning lime. Caliche is generally light-colored, but can range from white to light pink to reddish-brown, depending on the impurities present. It generally occurs on or near the surface, but can be found in deeper subsoil deposits, as well. Layers vary from a few inches to feet thick, and multiple layers can exist in a single location.

Ruby Saltbush
''Enchylaena tomentosa'', commonly known as barrier saltbush or ruby saltbush, is a small native shrub of Australia. Description ''Enchylaena tomentosa'' grows as a small perennial shrub, up to a meter in diameter. Leaves are slender and cylindrical growing to 6-15mm long, both leaves and stems are densely covered in woolly hairs. Fruits form as fleshy berries changing from bright green/yellow to bright red/orange. The derivation of the name helps describe and classify its features with ''Enchylaena'' coming from the Greek ''egchlos'' meaning fleshy or succulent and ''chlaen'' a cloak referring to the ripe fruiting perianth, ''tomentosa'' botanical Latin outlining that the plant is covered with dense short or curled hairs soft hair. Highly drought tolerant ''E. tomentosa'' has historically been sought after by Indigenous Australians, early settlers and livestock. Nutritional analyze gives the plant a 65% digestibility rating providing grazing species with 14% digestible protei ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Muehlenbeckia
''Muehlenbeckia'' or maidenhair is a genus of flowering plants in the family Polygonaceae. It is native to the borders of the Pacific, including South and North America, Papua New Guinea and Australasia. It has been introduced elsewhere, including Europe. Species vary in their growth habits, many being vines or shrubs. In some environments, rampant species can become weedy and difficult to eradicate. Description Species of ''Muehlenbeckia'' vary considerably in their growth habits; they may be perennials, vinelike, or shrubs. All have rhizomatous roots. Their leaves are arranged alternately on the stem, usually with stalks ( petioles), but sometimes stalkless (sessile). The brownish ocrea is short and tubular, soon disintegrating. The inflorescences may be terminal or axillary, and are in the form of spikes or clusters, with at most very short peduncles (flowering stems). Individual flowers have pedicels (stalks). The flowers may be bisexual or unisexual, with sometimes a mixtur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
