Persoonia Muelleri
''Persoonia muelleri'', commonly known as Mueller’s geebung, is a shrub endemic to Tasmania. It forms a shrub in open areas of wet forests in the west and northeast of the state. It is occasionally confused with '' P. gunnii'' though it has larger flowers and longer, straighter leaves. Description ''Persoonia muelleri'' grows as a shrub or small tree generally from tall, though sometimes plants reach high. Bark on larger branches and trunk is dark brown and flaky. It has narrow leaves measuring long and wide. New growth is covered in fine grey to tawny hair. The small flowers are yellow to cream. Var. ''muelleri'' flowers from December to February and var. ''densifolia'' from January to March. Taxonomy The French botanist Paul Évariste Parmentier described this species as ''Drimys muelleri'', placing it in the family Winteraceae, in 1896. Ferdinand von Mueller had sent him leaves and stems without any flowering parts, from which Parmentier had concluded it lay within the ...

Paul Évariste Parmentier
Paul Évariste Parmentier (29 April 1860 in Semmadon – 10 May 1941 in Besançon) was a French agronomist and botanist. He taught classes in the communities of Arbois (1882–89) and Baume-les-Dames (1889–98), and in the meantime, received his degree in natural sciences at Besançon (1889) and his doctorate from the University of Lyon (1892). From 1892 he was a professor of agricultural botany at the faculty of sciences of Besançon, where he taught classes up until 1930. At Besançon, he also served as director of its botanical garden.Racinescomtoises – Patrimoine et photographies de Franche-Comté (biography) From 1902 to 1919 he was director of the agricultural station of |
Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example ''Cytisus aeolicus'' is an endemite of the Italian flora. ''Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Shrub
A shrub (often also called a bush) is a small-to-medium-sized perennial woody plant. Unlike herbaceous plants, shrubs have persistent woody stems above the ground. Shrubs can be either deciduous or evergreen. They are distinguished from trees by their multiple stems and shorter height, less than tall. Small shrubs, less than 2 m (6.6 ft) tall are sometimes termed as subshrubs. Many botanical groups have species that are shrubs, and others that are trees and herbaceous plants instead. Some definitions state that a shrub is less than and a tree is over 6 m. Others use as the cut-off point for classification. Many species of tree may not reach this mature height because of hostile less than ideal growing conditions, and resemble a shrub-sized plant. However, such species have the potential to grow taller under the ideal growing conditions for that plant. In terms of longevity, most shrubs fit in a class between perennials and trees; some may only last about fiv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Winteraceae
Winteraceae is a primitive family of tropical trees and shrubs including 93 species in five genera. It is of particular interest because it is such a primitive angiosperm family, distantly related to Magnoliaceae, though it has a much more southern distribution. Plants in this family grow mostly in the southern hemisphere, and have been found in tropical to temperate climate regions of Malesia, Oceania, eastern Australia, New Zealand, Madagascar and the Neotropics, with most of the genera concentrated in Australasia and Malesia. The five genera, ''Takhtajania, Tasmannia, Drimys, Pseudowintera'', and ''Zygogynum s.l.'' all have distinct geographic extant populations. '' Takhtajania'' includes a single species, ''T. perrieri'', endemic only to Madagascar, ''Tasmannia'' has the largest distribution of genera in Winteraceae with species across the Philippines, Borneo, New Guinea, Eastern Australia, and Tasmannia, '' Drimys'' is found in the Neotropical realm, from southern Mexico to ...

Ferdinand Von Mueller
Baron Sir Ferdinand Jacob Heinrich von Mueller, (german: Müller; 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, 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 Ber ...

Drimys
''Drimys'' is a genus of about eight species of woody evergreen flowering plants, in the family Winteraceae. The species are native to the Neotropics, ranging from southern Mexico to the southern tip of South America. They are primitive dicots, associated with the humid temperate Antarctic flora of the Southern Hemisphere, which evolved millions of years ago on the ancient supercontinent of Gondwana. Members of the family generally have aromatic bark and leaves, and some are used to extract essential oils. ;Accepted species Seven species are currently accepted.''Drimys'' J.R.Forst. & G.Forst.

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 ...
