Lepidosperma tetraquetrum is a sedge of the family Cyperaceae that is native to Southwest Australia. [1]
The rhizomatous sedge typically grows to a height of two to three metres and with a spread of around two and a half metres wide. It is a tufted perennial with brownish inflorescence that appears sometime between November to December or January to March. In Western Australia it is found along the high rainfall southern coast, to the east of Albany on the Esperance Plains and north of Perth on the Swan Coastal Plain. Lepidosperma tetraquetrum occurs on sands with black peat near permanent water.
The first description was published by Christian Gottfried Daniel Nees von Esenbeck in the 1846 volume of Plantae Preissianae. [1] L. tetraquetrum, according to its conservation status, is not considered to be threatened. [1] The seed of the plant is favoured by red-eared firetails (Stagonopleura oculata), an endemic grass finch. [2]
The red-eared firetail, also known as the boorin, is a small finch-like species of bird. It occurs in dense wetland vegetation of coastal to sub-coastal regions in Southwest Australia. Its appearance is considered appealing, with white spots, black barring and vivid crimson marks at the ear and upper tail. Red-eared firetails are usually only glimpsed briefly, if at all, as they move rapidly and discreetly through their habitat. Most observations occur when their soft voice is heard, or in flight when flushed from the dense scrub. Males and females are similar in colouring and bond as lifelong pairs that occupy a territory centred on their roosting and brooding nest site. The species occupy a similar ecological niche to the beautiful firetail Stagonopleura bella found in the east of Australia, although unlike other species of the genus they only occasionally group together and are almost never seen in large flocks.
Lepidosperma gladiatum is commonly known as the coast sword-sedge or coastal sword-sedge. It is an evergreen species of sedge that is native to southern coastal areas of Australia. It was described by French botanist Jacques Labillardière in 1805. The Noongar name for the plant is kerbein.
Lepidosperma effusum, commonly known as the riverside sword sedge or spreading sword sedge, is an evergreen species of sedge that is native to southwest Western Australia.
Lepidosperma is a genus of flowering plant of the family Cyperaceae. Most of the species are endemic to Australia, with others native to southern China, southeast Asia, New Guinea, New Caledonia and New Zealand.
Lepidosperma longitudinale is commonly known as the pithy sword-sedge or pith saw-sedge. It is an evergreen species of sedge that is native to swampy areas of most Australian states. It was described by French botanist Jacques Labillardière in 1805.
Lepidosperma urophorum, the rapier saw sedge is a forest dwelling plant found in south eastern Australia. Often found on sandy soils near streams. It may grow to 1.5 metres high.
Lepidosperma laterale, commonly known as the variable swordsedge, is a plant found in south-eastern Australia, New Caledonia and New Zealand. It is often found on sandy soils or rocky areas in wooded areas.
Lepidosperma concavum, commonly known as the sandhill sword-sedge, is a plant found in coastal regions of south-eastern and eastern Australia. It grows on sandy soils in woodland, forest and heathland.
Lepidosperma filiforme, also known as the common rapier-sedge, is a sedge that occurs in coastal regions of south-eastern Australia and New Zealand. Plants grow to between 0.3 and 1 metre high. The culms are smooth, rigid, terete and between 0.7 and 2 mm in diameter. The leaves are also terete and about 1 mm in diameter, with sheaths that are straw coloured or reddish.
Lepidosperma elatius is a species of plant from sedge family that can be found in Australia. The plant grows to a height of 1–2.5 metres, with leaves and which are convex on both sides, with sharp margins. The spikelets have a drooping spray with a length of 18–65 centimetres (7.1–25.6 in). The plant flowers from November to April.
Lepidosperma chinense, also known as the Chinese scaleseed sedge, is a plant widely distributed across Fujian, Guangdong, Guangxi, Hainan, Hunan, Zhejiang, Indonesia, Malaysia, Papua New Guinea, and Vietnam.
Machaerina juncea, commonly known as bare twig-rush or tussock swamp twig rush, is a sedge in the sedge family, Cyperaceae, that is native to Australia, New Zealand, and New Caledonia.
Lepidosperma angustatum is a sedge of the family Cyperaceae that is native to Western Australia.
Lepidosperma benthamianum is a sedge of the family Cyperaceae that is native to Western Australia.
Zephyrarchaea mainae is a species of spider, informally known as Main's assassin spider, Albany assassin spider, and the Western archaeid spider. The first of the assassin spider family found in Western Australia, the species was unknown until its collection at Torndirrup National Park near Albany was published in 1987.
Lepidosperma squamatum is a species of flowering plant in the sedge family, Cyperaceae. It is native to Southwest Australia. It was described by Jacques Labillardière in Novae Hollandiae Plantarum Specimen (1805). The specific epithet squamatum is derived from the Latin for 'scale', in reference to the form of the bracts.
Lepidosperma leptostachyum is a species of flowering plant in the sedge family, Cyperaceae, a native of Southwest Australia.
Lepidosperma canescens is a sedge of the family Cyperaceae that is native to south-east South Australia and Victoria. There are no synonyms.
Lepidosperma amantiferrum is a sedge of the family Cyperaceae that is endemic to Western Australia. It has no synonyms.
Lepidosperma asperatum is a sedge that is endemic to Western Australia. It was first described in 1941 by Georg Kükenthal as Lepidosperma leptostachyum var. asperatum, but was elevated to species status in 2012 by Karen Wilson and Russell Barrett.
