Persoonioideae
The Persoonioideae are a subfamily of closely related genera within the large and diverse family Proteaceae and incorporates such genera as ''Persoonia'', '' Acidonia'', ''Garnieria'', '' Toronia'' and '' Placospermum''. Like most Proteaceae, the great majority of species of Persoonioideae are plants of well-drained, acid, siliceous soils that are low in nutrients. Two south western species ('' Acidonia microcarpa'', ''Persoonia graminea'') grow in swampy habitats, three others ('' P. acicularis'', '' P. bowgada'' and '' P. hexagona'') tolerate mildly calcareous soils, and several south eastern species sometimes grow on basalt-derived soils, and but these are exceptional. The greatest diversity of species is found in areas with soils derived from sandstones and granites. '' Placospermum coriaceum'' is the only species of Persoonioideae that usually completes its entire life cycle in rainforests. The others are basically plants of the shrubby strata of heathlands, and sclerophyl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Persoonia
''Persoonia'', commonly known as geebungs or snottygobbles, is a genus of about one hundred species of flowering plants in the family Proteaceae. Plants in the genus ''Persoonia'' are shrubs or small trees usually with smooth bark, simple leaves and usually yellow flowers arranged along a raceme, each flower with a leaf or scale leaf at the base. The fruit is a drupe. Description Persoonias are usually shrubs, sometimes small trees and usually have smooth bark. The adult leaves are simple, usually arranged alternately but sometimes in opposite pairs, or in whorls of three or four. If a petiole is present, it is short. The flowers are arranged singly or in racemes, usually of a few flowers, either in leaf axils or on the ends of the branches. Sometimes the raceme continues to grow into a leafy shoot. The tepals are free from each other except near their base, have their tips rolled back and are usually yellow. There is a single stigma on top of the ovary and surrounded by ...

Placospermum
''Placospermum'' is a genus of a single species of large trees, constituting part of the plant family Proteaceae. The species ''Placospermum coriaceum'' is endemic to the rainforests of the wet tropics region of northeastern Queensland, Australia. Common names include rose silky oak and plate-seeded oak. History The genus and species were first formally scientifically described in 1924 by Cyril T. White and William D. Francis. The precise relationships of the genus were unclear, though it was clear it was an early offshoot within the Proteaceae and retained primitive characteristics, until Lawrie Johnson and Barbara G. Briggs classified it in the subfamily Persoonioideae in their 1975 monograph " On the Proteaceae: the evolution and classification of a southern family". They noted that it had large chromosomes, like those of ''Persoonia'' and allied genera, as well as sharing some other primitive features.

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 ...

Persoonia Media
''Persoonia media'' is a species of flowering plant in the family Proteaceae and is endemic to eastern Australia. It is an erect to spreading shrub or tree with branchlets and leaves that are glabrous or only sparsely hairy, elliptic to egg-shaped leaves and up to sixteen yellow flowers on a rachis up to long. Description ''Persoonia media'' is a spreading shrub or tree that shows considerable variability, with a maximum height anywhere from to . Plants in dry sites south of the Macleay River grow from lignotubers and are short and multi-stemmed, while those growing in wetter areas are taller, single-stemmed and tend to have narrower leaves. The bark is smooth but finely fissured at the base of the trunk. Branchlets, leaves and flowers are glabrous or sparsely hairy with light brown to rust-coloured hairs. The leaves are elliptic to egg-shaped, long and wide with the edges rolled under. The flowers are arranged singly or in groups of up to sixteen on a rachis on a rachis up t ...

Garnieria
''Garnieria'' is a monotypic plant genus in the family Proteaceae. Molecular hylogenetic studies indicate that it is nested in the larger Australian genus ''Persoonia'' where it may be included. It is endemic to New Caledonia where the type specimen was collected at Prony Bay in 1868–1870 by Benjamin Balansa file:Benjamin Balansa par de Lacger Toulouse.jpg, Benjamin Balansa Gaspard Joseph Benedict Balansa, also known as Benjamin Balansa or Benedict Balansa (25 March 1825 – 2 November 1891) was a French botanist.

Toronia
''Toronia'' is a genus of tree in the family Proteaceae that contains a single species, ''Toronia toru'', which is endemic to New Zealand. The genus is closely related to the large genus ''Persoonia'', and in fact this species was long regarded as one until placed in its own new genus by Lawrie Johnson and Barbara G. Briggs in their 1975 monograph " On the Proteaceae: the evolution and classification of a southern family". However, phylogenetic studies indicate that ''Toronia'' is nested in the larger genus ''Persoonia'', where it was once included. ''Toronia toru'' is an evergreen tree found in the northern half of the North Island and is one of only two members of the protea ''Protea'' () is a genus of South African flowering plants, also called sugarbushes (Afrikaans: ''suikerbos'').

Acidonia Microcarpa
''Acidonia microcarpa'' is a species of shrub in the plant family Proteaceae. It is the only species in the genus ''Acidonia''. It is endemic to the south coast of the Southwest Botanic Province of Western Australia. It was originally published by Robert Brown in 1810 as a species of ''Persoonia''. In 1975, Lawrence Alexander Sidney Johnson and Barbara G. Briggs erected the genus ''Acidonia'', transferring a great many ''Persoonia'' species into it. Later, the circumscription of ''Acidonia'' was changed to include only ''A. microcarpa''. However, phylogenetic studies indicate that ''Acidonia'' is nested in the larger genus ''Persoonia ''Persoonia'', commonly known as geebungs or snottygobbles, is a genus of about one hundred species of flowering plants in the family Proteaceae.

Taxa Named By Barbara G
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eudicot Subfamilies
The eudicots, Eudicotidae, or eudicotyledons are a clade of flowering plants mainly characterized by having two seed leaves upon germination. The term derives from Dicotyledons. Traditionally they were called tricolpates or non-magnoliid dicots by previous authors. The botanical terms were introduced in 1991 by evolutionary botanist James A. Doyle and paleobotanist Carol L. Hotton to emphasize the later evolutionary divergence of tricolpate dicots from earlier, less specialized, dicots. Numerous familiar plants are eudicots, including many common food plants, trees, and ornamentals. Some common and familiar eudicots include sunflower, dandelion, forget-me-not, cabbage, apple, buttercup, maple, and macadamia. Most leafy trees of midlatitudes also belong to eudicots, with notable exceptions being magnolias and tulip trees which belong to magnoliids, and ''Ginkgo biloba'', which is not an angiosperm.

Association Of Societies For Growing Australian Plants
The Australian Native Plants Society (Australia) (ANPSA) is a federation of seven state-based member organisations for people interested in Australia's native flora, both in aspects of conservation and in cultivation. A national conference is held biennially for members of the state-based societies. The combined membership is around 9000 people. History The Society for Growing Australian Plants (SGAP) was established in 1957 by a group of people who "pledged to promote the establishment and breeding of Australian native plants for garden, park and farm". By 1958 active regional Societies had been established in six States and the ACT with the Federal Association (ASGAP) being formed in 1962 Initially the focus was on growing and learning about Australian Flora more for home and amenities plantings – members included botanists and horticulturists as well as enthusiastic laypeople. As time has gone on, there has been an increasing focus on conservation, and advocacy for conserv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
