Persoonia Terminalis
''Persoonia terminalis'', also known as the Torrington geebung, is a shrub belonging to the family Proteaceae, and native to northern New South Wales and southern Queensland in eastern Australia. Reported as a subspecies of ''Persoonia nutans'' in 1981, it was Species description, described as a species by Lawrence Alexander Sidney Johnson, Lawrie Johnson and his colleague Peter Weston in 1991. Two subspecies''P.t.terminalis'' and ''P.t.recurva''are recognised; both are found on well-drained soil pH, acidic soils in sclerophyll forests, and ''P.t.terminalis'' is also found on granite outcrops. Although similar in appearance, they differ in leaf length and curvature. Both have a restricted range, with ''P.t.terminalis'' found in an area of under . ''P.terminalis'' grows to , with an upright or spreading Habit (biology), habit, and narrow short leaves up to in length.

Australian National Botanic Gardens
The Australian National Botanic Gardens (ANBG) is a heritage-listed botanical garden located in , Canberra, in the Australian Capital Territory, Australia. Established in 1949, the Gardens is administered by the Australian Government's Department of Agriculture, Water and the Environment. The botanic gardens was added to the Commonwealth Heritage List on 22 June 2004. The botanic gardens is the largest living collection of native Australian flora. The mission of the ANBG is to "study and promote Australia's flora". The gardens maintains a wide variety of botanical resources for researchers and cultivates native plants threatened in the wild. The herbarium code for the Australian National Botanic Gardens is ''CANB''. History When Canberra was being planned in the 1930s, the establishment of the gardens was recommended in a report in 1933 by the Advisory Council of Federal Capital Territory. In 1935, The Dickson Report set forth a framework for their development. A large site fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Persoonia Terminalis Ssp Recurva, Australian National Botanic Garden, Canberra, ACT, 23-12-14 (16731755955)
''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 fou ...

Persoonia Sericea
''Persoonia sericea'', commonly known as the silky geebung, is a plant in the family Proteaceae and is endemic to eastern Australia. It is a shrub with hairy yellow flowers and silky-hairy young branches and leaves. Description ''Persoonia sericea'' is an erect to spreading shrub with its leaves and young branches covered with soft, silky hairs. The leaves are lance-shaped to egg-shaped, with the narrower end towards the base or elliptic to spatula-shaped and are long and wide. The flowers are hairy and are arranged singly or in small groups in leaf axils on a pedicel long. The flower is composed of four tepals long, which are fused at the base but with the tips rolled back. The central style is surrounded by four yellow anthers which are also joined at the base with the tips rolled back, so that it resembles a cross when viewed end-on. The ovary is densely hairy. Taxonomy and naming ''Persoonia sericea'' was first formally described in 1830 by Robert Brown from an unpublis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Persoonia Cornifolia
''Persoonia cornifolia'' is a plant in the family Proteaceae and is endemic to eastern Australia.

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] |
Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents (such as in blending inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridisation, which include genetic and morphological differences, differing times of fertility, mating behaviors and cues, and physiological rejection of sperm cells or the developing embryo. Some act before fertilization and others after it. Similar barriers exist in plants, with differences in flowering tim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Inflorescence
An inflorescence is a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches. Morphologically, it is the modified part of the shoot of seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the 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. 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. A flower that is not part of an inflorescence is called a solitary flower and its stalk is al ...

Christiaan Hendrik Persoon
Christiaan Hendrik Persoon (1 February 1761 – 16 November 1836) was a German mycologist who made additions to Linnaeus' mushroom taxonomy. Early life Persoon was born in South Africa at the Cape of Good Hope, the third child of an immigrant Pomeranian father and Dutch mother. His mother died soon after he was born; at the age of thirteen his father (who died a year later) sent him to Europe for his education. Education Initially studying theology at Halle, at age 22 (in 1784) Persoon switched to medicine at Leiden and Göttingen. He received a doctorate from the "Kaiserlich-Leopoldinisch-Carolinische Deutsche Akademie der Naturforscher" in 1799. Later years He moved to Paris in 1802, where he spent the rest of his life, renting an upper floor of a house in a poor part of town. He was apparently unemployed, unmarried, poverty-stricken and a recluse, although he corresponded with botanists throughout Europe. Because of his financial difficulties, Persoon agreed to dona ...
