Lasjia
''Lasjia'' is a genus of five species of trees of the family Proteaceae. Three species grow naturally in northeastern Queensland, Australia and two species in Sulawesi, Indonesia. Descriptively they are the tropical or northern macadamia trees group. ''Lasjia'' species characteristically branched compound inflorescences differentiate them from the ''Macadamia'' species, of Australia, which have characteristically unbranched compound inflorescences and only grow naturally about further to the south, in southern and central eastern Queensland and in northeastern New South Wales. The Bama aboriginal Australian peoples in the late 1800s Bellenden Ker Range rainforests (north east Queensland) taught European–Australian scientists of ''L. whelanii'' trees bearing the large seeds "extensively used for food". One of those scientists, colonial botanist Frederick M. Bailey, collected and in 1889 formally published a scientific description of specimens of them under the name ''Helicia w ...

Macadamia
''Macadamia'' is a genus of four species of trees in the flowering plant family Proteaceae. They are indigenous to Australia, native to northeastern New South Wales and central and southeastern Queensland specifically. 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, bauple nut and Hawaii nut. In Australian Aboriginal languages, the fruit is known by names such as ''bauple'', ''gyndl'' or ''jindilli'' (north of Great Dividing Range) and ''boombera'' (south of the Great Range). It was an important source of bushfood for the Aboriginal peoples who are the original inhabitants of the area. The nut was first commercially produced on a wide scale in Hawaii, where Australian seeds were introduced in the 1880s, and for some time, they were the world's largest producer. South Africa has been the world's largest producer of the maca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lasjia Whelanii
''Lasjia whelanii'', also known as Whelan's silky oak, Whelan's nut oak or Whelan's macadamia, is a species of large forest tree in the protea family that is endemic to north-eastern Queensland, Australia. History The tree was first described in 1889 by Queensland's colonial botanist Frederick Manson Bailey as a species of ''Helicia'', which in 1901 he moved to ''Macadamia'', but was transferred in 2008, in a paper in the ''American Journal of Botany'' by Peter Weston and Austin Mast, to the new genus ''Lasjia''. Description The dark green leaves are 6–21.5 cm long by 2–6.5 cm wide, with four or five leaves in each whorl. The white flowers grow as inflorescences. The globular fruits are 4–5 cm in diameter, with the seeds strongly cyanogenetic (cyanide producing) and poisonous to humans. It produces a useful timber, suitable for construction work. Distribution and habitat The species occurs in the Wet Tropics of Queensland, in well-developed lowland tr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lasjia Erecta
''Lasjia erecta'' is a species of forest tree in the protea family that is endemic to the island of Sulawesi, Indonesia. Its closest relative is ''Lasjia hildebrandii'', also a Sulawesi endemic. History The tree was first described in 1995 as a species of ''Macadamia'', but was transferred in 2008, in a paper in the ''American Journal of Botany'' by Peter Weston and Austin Mast, to the new genus ''Lasjia''. Description The species grows to about 14 m height, with a straight trunk up to 70 cm in diameter. The leaves are consistently 4-whorled, 4–9 cm long by 1.5–4.2 cm wide. The creamy-green flowers appear in erect terminal inflorescences. The round fruits are 2.5–3 cm in diameter. Distribution and habitat The species has been recorded from the province of Southeast Sulawesi, including the adjacent island of Kabaena, as well as from Lore Lindu National Park in Central Sulawesi. It grows on ultramafic soils at altitudes of 900–1,700 m. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lasjia Hildebrandii

Proteaceae
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 (''Telopea speciosissima''), king protea (''Protea cynaroides''), 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. Etymology The name Proteaceae was adapted by Robert Brown from the name Proteae coined in 1789 for the family by Antoine Laurent de Jussieu, based on the genus ''Protea'', which in 1767 Carl Linnaeus derived from t ...

Inflorescences
An inflorescence is a group or cluster of flowers arranged on a Plant stem, stem that is composed of a main branch or a complicated arrangement of branches. Morphology (biology), Morphologically, it is the modified part of the shoot of spermatophyte, seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the internode (botany), internodes and the phyllotaxis, as well as variations in the proportions, compressions, swellings, adnations, connations and reduction of main and secondary axes. One can also define an inflorescence as the reproductive portion of a plant that bears a cluster of flowers in a specific pattern. The stem holding the whole inflorescence is called a Peduncle (botany), peduncle. The major axis (incorrectly referred to as the main stem) above the peduncle bearing the flowers or secondary branches is called the rachis. The stalk of each flower in the inflorescence is called a Pedicel (botany) , ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type Species
In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.
