Posidonia coriacea is a species of seagrass that occurs in the southern waters of Australia.
A species of Posidonia . A perennial rhizomatous herb that appears as stands in marine habitat. This species is found at depths from 1 to 30 metres on white sands, in areas subject to intense wave action. The leaf blades are 2.5 to 7 millimetres wide, and 1.25 metres long. Two or three leaves, with large bases, appear from each shoot. They are leathery and thickened convexly on the upper and lower surfaces. Between 7 and 11 veins appear on each leaf. The leaf sheath breaks into strips, rather than the fibrous detritus of similar species. The flowering period is primarily during the months of August and September.
Posidonia coriacea is recorded at Shark Bay, Western Australia, around coasts of Southwest Australia, and across the Bight to South Australia.
This species is contained by the Posidoniaceae family, one of eight occurring in southern Australia. The ninth member, Posidonia oceanica , is found in the mediterranean sea. Several related species within Posidonia are described as the Posidonia ostenfeldii complex.
Eucalyptus marginata, commonly known as jarrah, djarraly in Noongar language and historically as Swan River mahogany, is a plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. It is a tree with rough, fibrous bark, leaves with a distinct midvein, white flowers and relatively large, more or less spherical fruit. Its hard, dense timber is insect resistant although the tree is susceptible to dieback. The timber has been utilised for cabinet-making, flooring and railway sleepers.
Nuytsia floribunda is a hemiparasitic tree found in Western Australia. The species is known locally as moodjar and, more recently, the Christmas tree or Western Australian Christmas tree. The display of intensely bright flowers during the austral summer coincides with the Christmas season.
Agonis flexuosa is a species of tree that grows in the southwest of Western Australia. It is easily the most common of the Agonis species, and is one of the most recognisable trees of Western Australia, being commonly grown in parks and on road verges in Perth.
Actinostrobus pyramidalis, commonly known as swamp cypress, Swan River cypress and King George's cypress pine, is a species of coniferous tree in the Cupressaceae. Like the other species in the genus Actinostrobus, it is endemic to southwestern Western Australia.
Acacia coriacea, commonly known as river jam, wirewood, desert oak, wiry wattle or dogwood, is a tree in the family Mimosoideae of family Fabaceae. Indigenous Australians know the plant as Gunandru.
Banksia xylothemelia is a sprawling woody shrub of the family Proteaceae endemic to southern Western Australia, one of the many species commonly known as dryandras and until recently called Dryandra xylothemelia. To date it is almost unknown in cultivation.
Macrozamia riedlei, commonly known as a zamia or zamia palm, is a species of cycad in the plant family Zamiaceae. It is endemic to southwest Australia and often occurs in jarrah forests. It may only attain a height of half a metre or form an above trunk up to two metres with long arching fronds of a similar length. The giant cones amidst the crown of palm-like fronds contain edible seeds surrounded by red sarcotesta. The seeds are consumed by birds and animals, and can be a favoured part of the human diet when prepared correctly. M. riedlei benefits from a close association with bacteria that fix nitrogen, which also produce substances found throughout the plant that are toxic to some animals when consumed. The species is cultivated for ornamental use in urban and domestic environments.
The Archipelago of the Recherche, known locally as the Bay of Isles, is a group of 105 islands, and over 1200 "obstacles to shipping", off the south coast of Western Australia. The islands stretch 230 km (140 mi) from east to west and to 50 km (31 mi) off-shore encompassing an area of approximately 4,000 square kilometres (1,544 sq mi). The western group is near Esperance and the eastern group at Israelite Bay. They are located in coastal waters, part of which is designated the Recherche Archipelago Nature Reserve.
Amphibolis antarctica is a species of flowering plant in the family Cymodoceaceae. It is referred to by the common names wire weed or sea nymph, and is a seagrass found in coastal waters of southern and western Australia.
Western Australia has the longest coastline of any state or territory in Australia, at 10,194 km or 12,889 km. It is a significant portion of the coastline of Australia, which is 35,877 km.
Posidonia australis, also known as fibre-ball weed or ribbon weed, is a species of seagrass that occurs in the southern waters of Australia. It forms large meadows important to environmental conservation. Balls of decomposing detritus from the foliage are found along nearby shore-lines.
Posidonia ostenfeldii is a species of seagrass that occurs in the southern waters of Australia.
Posidonia is a genus of flowering plants. It contains nine species of marine plants ("seagrass"), found in the seas of the Mediterranean and around the south coast of Australia.
The Seagrasses of Western Australia are submerged flowering plants found along the coast, around islands, and in Estuaries of Western Australia. The region contains some of the largest seagrass meadows in the world, and is the most diverse in the number of species. The variety of habitats along its western and southern coasts is often soft sands in shallow subtropical waters, ideal for these plants.
Gahnia trifida, the coastal saw-sedge, is a tussock-forming perennial in the family Cyperaceae, endemic to southern Australia.
Posidonia robertsoniae is one of the seagrasses of Western Australia, submerged flowering plants that occur in the southern coastal waters.
Persoonia coriacea, commonly known as the leathery-leaf persoonia, is a species of flowering plant in the family Proteaceae and is endemic to the south-west of Western Australia. It is an erect to spreading shrub with smooth bark, spatula-shaped or elliptic to linear leaves and bright yellow flowers borne in groups of up to ten along a rachis up to 70 mm (2.8 in) long.
Eucalyptus rhodantha, commonly known as rose mallee or rose gum, is a species of straggly mallee or shrub native to parts of Western Australia. It has smooth bark and a crown composed entirely of circular to heart-shaped juvenile leaves arranged in opposite pairs and attached directly to the stems with no stalks. The flower buds appear singly in the leaf axils and are red, the fruits hemispherical to conical and pendent. The rose mallee is grown as an ornamental shrub suitable for gardens in hot and dry climates. It is found more often in urban gardens and cultivation than in the wild and is readily available in seed form.
Acacia sericophylla is a shrub or tree commonly known as the desert dogwood, desert oak or cork-bark wattle. To the Indigenous Australian people of the Pilbara, the Nyangumarta peoples, it is known as Pirrkala. The species is of the genus Acacia and the subgenus Plurinerves.
Hakea francisiana, commonly called the emu tree, grass-leaf hakea or bottlebrush hakea, is a shrub or tree of the genus Hakea native to Western Australia and South Australia.
