Proteoideae
Proteoideae is one of the five subfamilies of the plant family Proteaceae. The greatest diversity is in Africa, but there are also many species in Australia; a few species occur in South America, New Caledonia, and elsewhere. Taxonomy Proteoideae was essentially defined by Robert Brown in his 1810 ''On the natural order of plants called Proteaceae''. Brown divided Proteaceae into two "sections" based on whether or not the fruits were dehiscent or indehiscence. He also noted that Brown's two "sections" corresponded closely with what are now recognised as the two largest Proteaceae subfamilies, Proteoideae and Grevilleoideae, and both the indehiscence of Proteoideae and the paired flowers of Grevilleoideae are still recognised as key diagnostic characters. Brown did not publish names for his two sections, and it would not be until 1836 that the name Proteoideae would be published by Amos Eaton. The modern framework for classification of the genera within Proteaceae was laid by L ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Protea Cynaroides
''Protea cynaroides'', also called the king protea, is a flowering plant. It is a distinctive member of ''Protea'', having the largest head (botany), flower head in the genus. The species is also known as giant protea, honeypot or king sugar bush. It is widely distributed in the southwestern and southern parts of South Africa in the fynbos region. The king protea is the national flower of South Africa. It also is the flagship of thProtea Atlas Project run by the South African National Botanical Institute. The king protea has several colour forms and horticulturists have recognized 81 garden varieties, some of which have injudiciously been planted in its natural range. In some varieties the pink of the flower and red borders of leaves are replaced by a creamy yellow. This unusual flower has a long vase life in flower arrangements, and makes for an excellent dried flower. ''Protea cynaroides'' is adapted to survive wildfires by its thick underground stem, which contains many dorm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cenarrhenes
''Cenarrhenes'' is a monytypic genus in the family Proteaceae containing the single species ''Cenarrhenes nitida'', known as the Port Arthur plum or native plum. ''Cenarrhenes nitida'' is an evergreen shrub to small tree endemic to the rainforests and scrublands of western Tasmania. It bears white flowers in late spring followed by the development of fleshy fruit. Taxonomy and naming The French naturalist and explorer Jacques Labillardière described ''Cenarrhenes nitida'' in 1805, from a location described as ''in capite Van Diemen'' (Tasmania). It still bears its common name today. The genus name is derived from the Ancient Greek words ''kenos'' "empty" and ''arrhen'' "male", referring to the four staminode-like hypogynous glands. The genus only bears the one species, its name the Latin adjective ''nitida'' "bright/shining", referring to its glossy leaves. Although it resembles the persoonias in appearance, it does not appear to be related to them. Instead, it has been group ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Eidothea
''Eidothea'' is a genus of two species of rainforest trees in New South Wales and Queensland, in eastern Australia, constituting part of the plant family Proteaceae. The plant family Proteaceae was named after the shape-shifting god Proteus of Greek mythology. The genus name ''Eidothea'' refers to one of the three daughters of Proteus. In 1883 German-Australian botanist Ferdinand von Mueller named fossil seeds '' Xylocaryon lockii'' from Miocene age sediments excavated in old gold mining sites in Victoria; they match those of ''Eidothea'' and are thought to represent the modern plant. ''Eidothea'' is known from geographic areas separated by more than , the mountains of the Wet Tropics of north-eastern Queensland, the Nightcap Range area of north-eastern New South Wales and as the fossils from southern Victoria, much further to the south, underlining the fact that Australia's rainforests are tiny remnants of ancient rainforests that millions of years ago covered large parts of ...

Beaupreopsis
''Beaupreopsis'' is a genus of plant in family Proteaceae, with just one species in the genus, ''Beaupreopsis paniculata''. It is native to New Caledonia on the south of Grand Terre. Its habitat is from open maquis, to mountain area as low scrub, on a substrate of eroded ultramafic rocks. Characteristics The plants are shrubs, rarely exceeding 1.50 m in height, with thick branches, scattered and few. They have pseudo-whorled leaves (5-10 x 0, 20-0, 60 cm), more or less toothed or lobed at the apex, cuneate at the base, leathery, venation slightly prominent, petiole short and robust. Flowers are small, white or pinkish in terminal panicles from 20 to 50 cm. The fruits are small and hairy, containing a single seed. Ecology The soils of ultramafic rocks, which are mining terrains, have been a refuge for many native plant species of New Caledonia because they are toxic and their mineral content is poorly suited to most foreign species of plants.Dossier > La flore de Nouv ...

Incertae Sedis
' () or ''problematica'' is a term used for a taxonomic group where its broader relationships are unknown or undefined. Alternatively, such groups are frequently referred to as "enigmatic taxa". In the system of open nomenclature, uncertainty at specific taxonomic levels is indicated by ' (of uncertain family), ' (of uncertain suborder), ' (of uncertain order) and similar terms. Examples *The fossil plant '' Paradinandra suecica'' could not be assigned to any family, but was placed ''incertae sedis'' within the order Ericales when described in 2001. * The fossil ''Gluteus minimus'', described in 1975, could not be assigned to any known animal phylum. The genus is therefore ''incertae sedis'' within the kingdom Animalia. * While it was unclear to which order the New World vultures (family Cathartidae) should be assigned, they were placed in Aves ''incertae sedis''. It was later agreed to place them in a separate order, Cathartiformes. * Bocage's longbill, ''Motacilla bocagii' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 sclerophyll fore ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bellendena
''Bellendena montana'', commonly known as mountain rocket, is a species of low-growing multi-stemmed shrub in the plant family Proteaceae. It is endemic to high-altitude subalpine and alpine regions in Tasmania, Australia. The prominent white flower spikes appear over summer, followed by small bright red or yellow fruit in late summer and autumn. Described by Robert Brown in 1810, it is the sole member of the genus ''Bellendena'', which is in turn the sole member of subfamily Bellendenoideae, and is thought to represent an early offshoot within the family. Taxonomy Scottish botanist Robert Brown described the mountain rocket in 1810 as ''Bellendena montana'', naming the genus in honour of John Bellenden Ker Gawler for his botanical works. The species name is the Latin adjective ''montanus'' and refers to its montane habitat. Its common name refers to its red-tipped rocket-shaped flowerheads. Phylogenetic studies often place this genus as basal (one of the earliest offshoots) t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
