Tetragonia nigrescens is a plant native to southern Africa.
The prostrate herb blooms in September producing yellow flowers and grows well in sandy soils at lower altitudes. [1]
A species that varies greatly in its inflorescence, leaf shape and hairiness. However, its flowers are typically axillary, and born in umbellate clusters (although these axillary umbels can sometimes instead grow as small branchlets with both flowers and tiny leaves).
The lower leaves are usually obtuse and when dried, the entire plant turns a very dark colour (almost black). [2]
This species is indigenous to the far western edge of the Cape provinces, South Africa. It naturally occurs from Namaqualand in the north, southwards through Stellenbosch and Worcester, as far south as Struisbaai near Agulhas. [3]
It has become naturalised in Western Australia in a coastal area around Perth. [1]
Carpobrotus edulis is a ground-creeping plant with succulent leaves in the genus Carpobrotus, native to South Africa. It is known as hottentot-fig, sour fig, ice plant or highway ice plant.
The Aizoaceae, or fig-marigold family, is a large family of dicotyledonous flowering plants containing 135 genera and about 1800 species. They are commonly known as ice plants or carpet weeds. They are often called vygies in South Africa and New Zealand. Highly succulent species that resemble stones are sometimes called mesembs.
Tetragonia is a genus of about 85 species of flowering plants in the family Aizoaceae, native to temperate and subtropical regions mostly of the Southern Hemisphere, in New Zealand, Australia, southern Africa and South America.
Banksia coccinea, commonly known as the scarlet banksia, waratah banksia or Albany banksia, is an erect shrub or small tree in the family Proteaceae. Its distribution in the wild is along the south west coast of Western Australia, from Denmark to the Stokes National Park, and north to the Stirling Range, growing on white or grey sand in shrubland, heath or open woodland. Reaching up to 8 m (26 ft) in height, it is a single-stemmed plant that has oblong leaves, which are 3–9 cm (1.2–3.5 in) long and 2–7 cm (0.8–2.8 in) wide. The prominent red and white flower spikes appear mainly in the spring. As they age they develop small follicles that store seeds until opened by fire. Though widely occurring, it is highly sensitive to dieback and large populations of plants have succumbed to the disease.
Tetragonia tetragonioides, commonly called New Zealand spinach and other local names, is a flowering plant in the fig-marigold family (Aizoaceae). It is often cultivated as a leafy vegetable.
Banksia tricuspis, commonly known as Lesueur banksia or pine banksia, is a plant in the family Proteaceae and is endemic to a small area in the south-west of Western Australia. It is a stunted tree or shrub with narrow leaves and cylindrical spikes of golden-coloured flowers and it occurs in a geographic range of just 15 square kilometres near Jurien.
The Proteaceae form a family of flowering plants predominantly distributed in the Southern Hemisphere. The family comprises 83 genera with about 1,660 known species. Together with the Platanaceae and Nelumbonaceae, they make up the order Proteales. Well-known genera include Protea, Banksia, Embothrium, Grevillea, Hakea and Macadamia. Species such as the New South Wales waratah, king protea, and various species of Banksia, soman, and Leucadendron are popular cut flowers. The nuts of Macadamia integrifolia are widely grown commercially and consumed, as are those of Gevuina avellana on a smaller scale. Australia and South Africa have the greatest concentrations of diversity.
Banksia splendida, commonly known as shaggy dryandra, is a species of shrub that is endemic to the southwest of Western Australia. It has sharply-pointed linear leaves that are woolly on the lower surface, cream-coloured and maroon or yellow flowers in heads of between 65 and 115, and later up to eight egg-shaped follicles in each head.
Acacia paradoxa is a plant in the family Fabaceae. Its common names include kangaroo acacia, kangaroo thorn, prickly wattle, hedge wattle and paradox acacia.
Disphyma crassifolium, commonly known as round-leaved pigface, is a species of flowering plant in the family Aizoaceae and is native to Australia and the Cape Provinces of South Africa. It is a prostrate, succulent annual shrub or short-lived Perennial plant with stems up to 2 m long, leaves that are three-sided in cross-section with a rounded lower angle, and purple daisy-like flowers with staminodes up to 30 mm (1.2 in) long.
Tetragonia decumbens is a coastal shrub, native to southern Africa.
Persoonia gunnii is a species of flowering plant in the family Proteaceae and is endemic to Tasmania. It is an erect shrub with young branchlets that are hairy at first, spatula-shaped to egg-shaped leaves with the narrower end towards the base, and white to cream-coloured flowers.
Galenia secunda is a plant species native to South Africa but naturalized in Australia, Spain, and the United States. In Spain and Australia, is considered an invasive weed threatening native vegetation.
Grevillea coccinea is a species of flowering plant in the family Proteaceae and is endemic to the south of Western Australia. It is a low-lying or sprawling shrub with narrowly wedge-shaped to linear leaves and white, cream-coloured, and red or yellow flowers.
Hypertelis is a genus of flowering plants in the family Molluginaceae. Most of its former species have been transferred to the new genus Kewa, and the remaining species, Hypertelis spergulacea, may also need a different placement. Hypertelis spergulacea is a woody-based plant, up to 30 cm (1 ft) high, with whorled greyish green leaves. It is found on the border between Namibia and the Northern Cape province of South Africa.
Petrophile axillaris is a species of flowering plant in the family Proteaceae and is endemic to southwestern Western Australia. It is a shrub with pinnately-divided, sharply-pointed leaves, and spherical heads of hairy pink or grey flowers.
Wahlenbergia tenella is a herbaceous plant in the family Campanulaceae native to the southern Cape regions of South Africa.
Wahlenbergia loddigesii is a herbaceous plant in the family Campanulaceae native to the southern Cape regions of South Africa.
Tetragonia spicata is a Southern African perennial shrub or scrambler.
Tetragonia echinata is a Southern African annual spreading plant, common in open or disturbed areas.
