Macadamia
''Macadamia'' is a genus of four species of trees in the flowering plant family Proteaceae. They are indigenous to Australia—specifically, northeastern New South Wales and central and southeastern Queensland. Two species of the genus are commercially important for their fruit, the macadamia nut (or simply macadamia). Global production in 2015 was . Other names include Queensland nut, bush nut, maroochi nut or bauple nut. It was an important source of Bush tucker, bushfood for the Aboriginal Australians, Aboriginal peoples. The nut was first commercially produced on a wide scale in Hawaii, where Australian seeds were introduced in the 1880s, and which for more than a century was the world's largest producer. South Africa has been the world's largest producer of the macadamia since the 2010s. The macadamia is the only widely grown food plant that is native to Australia.

Macadamia Jansenii
''Macadamia jansenii'' is an endangered and poisonous tree in the flowering plant family Proteaceae, native to Queensland in Australia. It was only described as a new species in 1991, being first brought to the attention of plant scientists in 1983 by Ray Jansen, a sugarcane farmer and amateur botanist from South Kolan in Central Queensland. Closely related to the cultivated and recently domesticated macadamia nut, it has small 11–16 mm diameter nuts that have a smooth, hard, brown shell enclosing a cream, globulose kernel that is bitter and inedible. In the wild it grows as a multi-stemmed 6–9m tall evergreen tree, with leaves having entire margins and generally in whorls of 3. An extremely rare species, it was discovered as a single population of around 60 plants in the wild in Eastern Australia. In 2018 about 60 new mature ''Macadamia jansenii'' trees were located, [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Proteaceae
The Proteaceae form a family (biology), family of flowering plants predominantly distributed in the Southern Hemisphere. The family comprises 83 genus, genera with about 1,660 known species. Australia and South Africa have the greatest concentrations of diversity. Together with the Platanaceae (plane trees), Nelumbonaceae (the sacred lotus) and in the recent APG IV system the Sabiaceae, they make up the order Proteales. Well-known Proteaceae genera include ''Protea'', ''Banksia'', ''Embothrium'', ''Grevillea'', ''Hakea'', and ''Macadamia''. Species such as the New South Wales waratah (''Telopea speciosissima''), king protea (''Protea cynaroides''), and various species of ''Banksia'', ''Grevillea'', 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. Etymology The name Proteaceae was adapted by Robert Brown (botanist, born 1773), Robert Brown from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bush Tucker
Bush tucker, also called bush food, is any food native to Australia and historically eaten by Indigenous Australians and Torres Strait Islander peoples, but it can also describe any native flora, fauna, or fungi used for culinary or medicinal purposes, regardless of the continent or culture. Animal native foods include kangaroo, emu, witchetty grubs and crocodile, and plant foods include fruits such as quandong, kutjera, spices such as lemon myrtle and vegetables such as warrigal greens and various native yams. Traditional Indigenous Australians' use of bushfoods has been severely affected by the colonisation of Australia beginning in 1788 and subsequent settlement by non-Indigenous peoples. The introduction of non-native organisms, together with the loss of and destruction of traditional lands and habitats, has resulted in reduced access to native foods by Aboriginal people. Since the 1970s, there has been recognition of the nutritional and gourmet value of native foods ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ferdinand Von Mueller
Baron Sir Ferdinand Jacob Heinrich von Mueller, (; 30 June 1825 – 10 October 1896) was a German-Australian physician, geographer, and most notably, a botanist. He was appointed government botanist for the then colony of Victoria, Australia by Governor Charles La Trobe in 1853, and later director of the Royal Botanic Gardens in Melbourne. He also founded the National Herbarium of Victoria. He named many Australian plants. Early life Mueller was born at Rostock, in the Grand Duchy of Mecklenburg-Schwerin. After the early death of his parents, Frederick and Louisa, his grandparents gave him a good education in Tönning, Schleswig. Apprenticed to a chemist at the age of 15, he passed his pharmaceutical examinations and studied botany under Professor Ernst Ferdinand Nolte (1791–1875) at Kiel University. In 1847, he received his degree of Doctor of Philosophy from Kiel for a thesis on the plants of the southern regions of Schleswig. Mueller's sister Bertha had been advi ...

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. 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 of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Hawaii
Hawaii ( ; ) is an island U.S. state, state of the United States, in the Pacific Ocean about southwest of the U.S. mainland. One of the two Non-contiguous United States, non-contiguous U.S. states (along with Alaska), it is the only state not on the North American mainland, the only state that is an archipelago, and the only state in the tropics. Hawaii consists of 137 volcanic islands that comprise almost the entire Hawaiian Islands, Hawaiian archipelago (the exception, which is outside the state, is Midway Atoll). Spanning , the state is Physical geography, physiographically and Ethnology, ethnologically part of the Polynesian subregion of Oceania. Hawaii's ocean coastline is consequently the List of U.S. states and territories by coastline, fourth-longest in the U.S., at about .

Follicle (fruit)
In botany, a follicle is a dry unilocular fruit formed from one carpel, containing two or more seeds. It is usually defined as dehiscing by a suture in order to release seeds, for example in '' Consolida'' (some of the larkspurs), peony and milkweed (''Asclepias''). Some difficult cases exist however, so that the term indehiscent follicle is sometimes used, for example with the genus '' Filipendula'', which has indehiscent fruits that could be considered intermediate between a (dehiscent) follicle and an (indehiscent) achene. An aggregate fruit that consists of follicles may be called a follicetum. Examples include hellebore, aconite, ''Delphinium ''Delphinium'' is a genus of about 300 species of annual and perennial flowering plants in the family (biology), family Ranunculaceae, native species, native throughout the Northern Hemisphere and also on the high mountains of tropical Africa.

Tepal
A tepal is one of the outer parts of a flower (collectively the perianth). The term is used when these parts cannot easily be classified as either sepals or petals. This may be because the parts of the perianth are undifferentiated (i.e. of very similar appearance), as in ''Magnolia'', or because, although it is possible to distinguish an outer whorl of sepals from an inner whorl of petals, the sepals and petals have similar appearance to one another (as in ''Lilium''). The term was first proposed by Augustin Pyramus de Candolle in 1827 and was constructed by analogy with the terms "petal" and "sepal". (De Candolle used the term ''perigonium'' or ''perigone'' for the tepals collectively; today, this term is used as a synonym for ''perianth''.) p. 39. Origin Undifferentiated tepals are believed to be the ancestral condition in flowering plants. For example, ''Amborella'', which is thought to have separated earliest in the evolution of flowering plants, has flowers with undiffer ...
