It was previously regarded as the sole genus in the family Oliniaceae, but is now included in the expanded Penaeaceae along with ''Rhynchocalyx'' (formerly of the Rhynchocalycaceae) under the APG III system The APG III system of flowering plant classification is the third version of a modern, mostly molecular-based, system of plant taxonomy being developed by the Angiosperm Phylogeny Group (APG).

Olinia Ventosa
''Olinia ventosa'', commonly known as the hard-pear. is a large, evergreen forest tree indigenous to South Africa. Appearance The hard-pear is a large tree that usually grows to 15–20 meters in height. When exposed to harsh conditions, it forms a smaller tree or shrub. The bark is originally smooth and grey, but it becomes rough, flaky, fissured and reddish as the tree matures. The leathery, dark green, glossy leaves appear in opposite pairs, while the pinkish-white, fragrant, bisexual flowers appear in bunches at branch ends in the spring. The tree very occasionally bears pinkish-red berries. The hard-pear can sometimes be identified by the strong smell of almonds given off by the crushing of its leaves. Distribution ''Olinia ventosa'' is a native of the southern and eastern coastal regions of South Africa, from the Cape Peninsula to southern KwaZulu-Natal. Its natural habitat is afro-montane forests, especially the forest margins, as well as coastal scrub and rocky hil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
APG III System
The APG III system of flowering plant classification is the third version of a modern, mostly molecular-based, system of plant taxonomy being developed by the Angiosperm Phylogeny Group (APG). Published in 2009, it was superseded in 2016 by a further revision, the APG IV system. Along with the publication outlining the new system, there were two accompanying publications in the same issue of the Botanical Journal of the Linnean Society: * The first, by Chase & Reveal, was a formal phylogenetic classification of all land plants (embryophytes), compatible with the APG III classification. As the APG have chosen to eschew ranks above order, this paper was meant to fit the system into the existing Linnaean hierarchy for those that prefer such a classification. The result was that all land plants were placed in the class Equisetopsida, which was then divided into 16 subclasses and a multitude of superorders. * The second, by Haston ''et al.'', was a linear sequence of families followi ...

Rhynchocalyx
''Rhynchocalyx lawsonioides'' is a small flowering tree, the sole species of the genus ''Rhynchocalyx''. It had also previously been regarded as the only species in the monogeneric family Rhynchocalycaceae but is now included in the expanded Penaeaceae along with ''Olinia'' (formerly of the Oliniaceae) under the APG III system of classification. ''Rhynchocalyx'' is endemic to the KwaZulu-Cape coastal forest mosaic ecoregion of the Natal and Eastern Cape provinces of South Africa South Africa, officially the Republic of South Africa (RSA), is the southernmost country in Africa.

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 countries of Namibia, Botswana, and Zimbabwe; and to the east and northeast by Mozambique and Eswatini. 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.

Africa
Africa is the world's second-largest and second-most populous continent, after Asia in both cases. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area and 20% of its land area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With billion people as of , it accounts for about of the world's human population. Africa's population is the youngest amongst all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Despite a wide range of natural resources, Africa is the least wealthy continent per capita and second-least wealthy by total wealth, behind Oceania. Scholars have attributed this to different factors including geography, climate, tribalism, colonialism, the Cold War, neocolonialism, lack of democracy, and corruption. Despite this low concentration of wealth, recent economic expansion and the large and young population make Afr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Carl Peter Thunberg
Carl Peter Thunberg, also known as Karl Peter von Thunberg, Carl Pehr Thunberg, or Carl Per Thunberg (11 November 1743 – 8 August 1828), was a Swedish naturalist and an "apostle" of Carl Linnaeus. After studying under Linnaeus at Uppsala University, he spent seven years travelling in southern Africa and Asia, collecting and describing many plants and animals new to European science, and observing local cultures. He has been called "the father of South African botany", "pioneer of Occidental Medicine in Japan", and the "Japanese Linnaeus". Early life Thunberg was born and grew up in Jönköping, Sweden. At the age of 18, he entered Uppsala University where he was taught by Carl Linnaeus, regarded as the "father of modern taxonomy". Thunberg graduated in 1767 after 6 years of studying. To deepen his knowledge in botany, medicine and natural history, he was encouraged by Linnaeus in 1770 to travel to Paris and Amsterdam. In Amsterdam and Leiden Thunberg met the Dutch botanist ...
