It is an abundant and common species in the southwestern cape, South Africa South Africa, officially the Republic of South Africa (RSA), is the southernmost country in Africa. It is bounded to the south by of coastline that stretch along the South Atlantic and Indian Oceans; to the north by the neighbouring countri ... (Namaqualand to Grahamstown). It is most commonly found on lower north-facing slopes, especially on rocky clay and shale based soils. Description ''Oedera genistifolia'' is a small (60cm high), erect shrublet. The leaves, which grow densely packed along the stems, are small (15mm), thin (3mm), straight, suberect, usually mucronate, and slightly furry along their margins and lower midrib. The leaf has a short point (mucro) at its tip, which is usually slightly hooked downwards. The leaf surfaces are also glandular, and the surface of the young leaves ...

Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ...

Asteraceae
The family Asteraceae, alternatively Compositae, consists of over 32,000 known species of flowering plants in over 1,900 genera within the order Asterales. Commonly referred to as the aster, daisy, composite, or sunflower family, Compositae were first described in the year 1740. The number of species in Asteraceae is rivaled only by the Orchidaceae, and which is the larger family is unclear as the quantity of extant species in each family is unknown. Most species of Asteraceae are annual, biennial, or perennial herbaceous plants, but there are also shrubs, vines, and trees. The family has a widespread distribution, from subpolar to tropical regions in a wide variety of habitats. Most occur in hot desert and cold or hot semi-desert climates, and they are found on every continent but Antarctica. The primary common characteristic is the existence of sometimes hundreds of tiny individual florets which are held together by protective involucres in flower heads, or more technicall ...

South Africa
South Africa, officially the Republic of South Africa (RSA), is the southernmost country in Africa.

It also completely enclaves the country Lesotho. It is the southernmost country on the mainland of the Old World, and the second-most populous country located entirely south of the equator, after Tanzania. South Africa is a biodiversity hotspot, with unique biomes, plant and animal life. With over 60 million people, the country is the world's 24th-most populous nation and covers an area of . South Africa has three capital cities, with the executive, judicial and legislative branches of government based in Pretoria, Bloemfontein, and Cape Town respectively. The largest city is Johannesburg. About 80% of the population are Black South Afri ...

Oedera Squarrosa
''Oedera squarrosa'' ("Vierkant-perdekaroo") is a prickly shrublet belonging to the family Asteraceae. It is an abundant and common species in the southwestern Cape Provinces of South Africa ( Namaqualand to Port Elizabeth). It is most commonly found in close proximity to the main mountain ranges, especially in rocky loamy or clayey soils. Description ''Oedera squarrosa'' is a small, erect shrublet (60cm high). The leaves are small (15mm x 7mm), ovate, glandular and down-curved, with thickened margins, and grow densely packed along the stems. On the younger stems, the leaves are usually in four ranks. Older stems often have a more imbricate arrangement. Tufts of a couple of yellow flowerheads appear at the tips of the branches in Spring and Summer. They are 10mm wide, with relatively short stalks (2-10mm). Related species ''Oedera squarrosa'' is closely related to ''Oedera genistifolia ''Oedera genistifolia'' ("Klein Perdekaroo") is a prickly shrublet belonging to t ...

Endemic Flora Of The Cape Provinces
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ...

''Oedera'' is a genus of African flowering plants in the tribe Gnaphalieae within the family Asteraceae. The genus is named in honor of the Danish botanist Georg Christian Oeder. The species have yellow central and ray florets in their flower-heads. Their seeds all have a little crown of scales, and the leaves are often fragrant and unpalatable for stock grazing. ; Species Species accepted by the Plants of the World Online as of March 2024: *'' Oedera acerosa'' *'' Oedera calycina'' *'' Oedera capensis'' *'' Oedera conferta'' *'' Oedera corymbosa'' *'' Oedera decussata'' *'' Oedera dieterlenii'' *'' Oedera epaleacea'' *''Oedera flavicoma'' *'' Oedera foveolata'' *''Oedera fruticosa'' *'' Oedera garnotii'' *''Oedera genistifolia'' *''Oedera glandulosa'' *''Oedera hirta'' *''Oedera humilis'' *''Oedera imbricata'' *''Oedera intermedia'' *''Oedera laevis'' *''Oedera longipes'' *''Oedera montana'' *''Oedera muirii'' *'' Oedera multipunctata'' *'' Oedera nor ...
