Thamnochortus insignis is a species of grass-like restio of the family Restionaceae, endemic to Cape Province in South Africa. [1]
Plants are tall, grass- or reed-like tussocks with a diameter of 500 mm to 1 metre at the base and a spread of 3 metres or more at the top and up to 2,5 m tall. Male and female plants are separate and very similar when they are not flowering.
Thamnochortus insignis grows in dense stands in the southern Cape around Albertinia. It can now be found along the roadsides from Port Elizabeth to the Cedarberg, where the seed has been distributed by the trucks carrying the thatching material. [2]
The plants are wind pollinated with the male inflorescences in small tassels swaying in the wind, while the female flowers are at the base of medium sized bracts, which catch the pollen from the air and funnel it towards the small fringed styles of the female flowers.
The seed comes in the form of a tiny nutlet inside the old flower, which by this stage has formed two small wings. This helps the wind to carry the seeds away from the plant. The seeds are produced in very large quantities by each female plant, but are not all viable; a large number of nutlets are empty inside. Why the plants expend all this energy to produce sterile seeds is not clear, but is particular to this genus as well as to the genus Elegia .
This restio is widely cultivated both for its usefulness as a thatching material as its name shows.
Thamnochortus insignis is used as an ornamental plant. It is excellent in pots and can be easily established outside in mild districts (in the Northern Hemisphere). It is hardy to -3 °C.
The popularity of this species and the subsequent cultivation of it has led to the result in the elimination of other plant species in its native area.
Lodoicea, commonly known as the sea coconut, coco de mer, or double coconut, is a monotypic genus in the palm family. The sole species, Lodoicea maldivica, is endemic to the islands of Praslin and Curieuse in the Seychelles. It formerly also was found on the small islets of St Pierre, Chauve-Souris and Ile Ronde, all located near Praslin, but had become extinct there for a time until recently reintroduced. The name of the genus, Lodoicea, may be derived from Lodoicus, one Latinised form of Louis, in honour of King Louis XV of France. Other sources say that Lodoicea is from Laodice, the daughter of Priam and Hecuba.
Reed is a common name for several tall, grass-like plants of wetlands.
The Restionaceae, also called restiads and restios, are a family of flowering plants native to the Southern Hemisphere; they vary from a few centimeters to 3 meters in height. Following the APG IV (2016): the family now includes the former families Anarthriaceae, Centrolepidaceae and Lyginiaceae, and as such includes 51 genera with 572 known species. Based on evidence from fossil pollens, the Restionaceae likely originated more than 65 million years ago during the Late Cretaceous period, when the southern continents were still part of Gondwana.
Pandanus tectorius is a species of Pandanus (screwpine) that is native to Malesia, eastern Australia, and the Pacific Islands. It grows in the coastal lowlands typically near the edge of the ocean. Common names in English include thatch screwpine, Tahitian screwpine, hala tree, pandanus, and pu hala in Hawaiian. The fruit is sometimes known as hala fruit.
Anemophily or wind pollination is a form of pollination whereby pollen is distributed by wind. Almost all gymnosperms are anemophilous, as are many plants in the order Poales, including grasses, sedges, and rushes. Other common anemophilous plants are oaks, pecans, pistachios, sweet chestnuts, alders and members of the family Juglandaceae. Approximately 12% of plants across the globe are benefited by anemophily, including cereal crops like rice and corn and other prominent crop plants like wheat, rye, barley, and oats. In addition, many pines, spruces, and firs are wind-pollinated, and people rely on these hardwood trees for their survival.
Leucadendron is a genus of about 80 species of flowering plants in the family Proteaceae, endemic to South Africa, where they are a prominent part of the fynbos ecoregion and vegetation type.
Plant reproduction is the production of new offspring in plants, which can be accomplished by sexual or asexual reproduction. Sexual reproduction produces offspring by the fusion of gametes, resulting in offspring genetically different from the parent or parents. Asexual reproduction produces new individuals without the fusion of gametes, genetically identical to the parent plants and each other, except when mutations occur.
Protea neriifolia, also known as the narrow-leaf sugarbush, oleander-leaved sugarbush, blue sugarbush, or the oleanderleaf protea, is a flowering plant in the genus Protea, which is endemic to South Africa.

Celtis africana, the white stinkwood, is a deciduous tree in the family Cannabaceae. Its habit ranges from a tall tree in forest to a medium-sized tree in bushveld and open country, and a shrub on rocky soil. It occurs in Yemen and over large parts of Africa south of the Sahara. It is a common tree in the south and east of southern Africa, where the odour given off by freshly-cut green timber is similar to that of Ocotea bullata or Black Stinkwood.
Thalassia testudinum, commonly known as turtlegrass, is a species of marine seagrass. It forms meadows in shallow sandy or muddy locations in the Caribbean Sea and the Gulf of Mexico. Turtle grass and other seagrasses form meadows which are important habitats and feeding grounds. The grass is eaten by turtles and herbivorous fish, supports many epiphytes, and provides habitat for juvenile fish and many invertebrate taxa.
Austroderia richardii, syn. Cortaderia richardii, is a species of flowering plant in the family Poaceae. It is an evergreen perennial grass. The genus Austroderia is often called "pampas grass", though this name usually refers to A. selloana. "Early pampas-grass" is a more specific name. The name "tussock grass" may also be found. The Maori name is "toetoe". It is one of five species in the genus Austroderia that are endemic to New Zealand. It occurs in the South Island and possibly also in the North Island. It is also an introduced species in Tasmania, Australia.
Metalasia muricata (L.) D.Don, commonly known as 'White Bristle Bush' or 'Blombos', is a hardy virgate or twiggy shrub with honey-scented flowers usually 2–4 m tall, woody with a rounded crown, and an important component of the coastal and mountain fynbos regions of Southern Africa. It is encountered in a number of forms in its extended distribution, some of which are tolerant of frost, wind and poor sandy soils. A member of the Asteraceae or Daisy family, Metalasia has some 54 species in South Africa, many of them found in the Western Cape. The name of the genus Metalasia is derived from 'meta' which can have many meanings, but in this case is intended as 'reverse', and 'lasios' meaning 'woolly', an allusion to the woolly reverse sides of the leaves; 'muricata' means warty with short, sharp points like the shell of the Murex. Metalasia is also found in KwaZulu-Natal, Free State, Eastern Cape and Lesotho.
Elegia tectorum, previously Chondropetalum tectorum or Restio tectorum, more commonly Cape thatching reed, or dakriet, is a member of the restio family, Restionaceae. It is a tufted perennial growing to between 1.5 and 2.25 m, with deciduous leaf sheaths. Flowers are less than 3 mm long. Petals are smooth or hairy in the upper half. E. tectorum is found in marshes and seeps on deep sand in the Western Cape and Eastern Cape of South Africa.
Thamnochortus is a group of plants in the Restionaceae described as a genus in 1767. The entire genus is endemic to Cape Province in South Africa.
Protea recondita, also known as the hidden sugarbush, is a flowering plant of the genus Protea within the family Proteaceae, which is endemic to the Cape Region of South Africa, and distributed from the Piketberg and Cederberg to the Groot Winterhoek mountains. The flowers of this unusual plant are pollinated by non-flying mammals: rodents and elephant shrews. In the Afrikaans language it is known as gesigtoehouprotea or skaamroos.
Protea angustata, also known as the Kleinmond sugarbush, is a flowering shrub that belongs to the genus Protea. This plant is endemic to the south-west Cape Region of South Africa.
Protea lorea, also known as the thong-leaf sugarbush, is a flowering shrub belonging to the genus Protea.
Protea restionifolia, which is also known as the Reed-leaf sugarbush, is a flowering shrub endemic to the Western Cape province of South Africa where it is found from the upper part of the Breede River Valley through the Bot River Valley to Wolseley and the Koue Bokkeveld Mountains.
Protea odorata is a small, sparsely branched, unisexual evergreen shrub that grows up to 1.5 metres tall. It has light green branches that turn brown with age and produce leaves that are upward or arched like leaves. The leaves are hairless and have a curved back and tips that can easily hurt the hand when touched. The leaves become black with age and the spines are pink or reddish in young years, but turn brown and brown with age.
