Styphelia Pentapogona
''Styphelia pentapogona'' is a species of flowering plant in the heath family Ericaceae and is endemic to the south-west of Western Australia. It is a diffuse shrub with many erect or ascending branchlets, crowded egg-shaped or lance-shaped leaves about long, with a small point on the tip. The flowers are borne in lower leaf axils and are sessile with very small bracts and bracteoles less than long at the base. The petals are joined at the base forming a tube about long with bearded lobes. ''Styphelia pentapogona'' was first formally described in 1867 by Ferdinand von Mueller in his ''Fragmenta phytographiae Australiae'' from specimens collected by George Maxwell.

Ericaceae
The Ericaceae () are a Family (biology), family of flowering plants, commonly known as the heath or heather family, found most commonly in acidic and infertile growing conditions. The family is large, with about 4,250 known species spread across 124 genera, making it the 14th most species-rich family of flowering plants. The many well known and economically important members of the Ericaceae include the cranberry, blueberry, huckleberry, rhododendron (including azaleas), and various common heaths and heathers (''Erica (plant), Erica'', ''Cassiope'', ''Daboecia'', and ''Calluna'' for example). Description The Ericaceae contain a morphologically diverse range of taxa, including Herbaceous plant, herbs, chamaephyte, dwarf shrubs, shrubs, and trees. Their leaves are usually evergreen, alternate or whorled, simple and without stipules. Their flowers are Plant sexuality#Individual plant sexuality, hermaphrodite and show considerable variability. The petals are often fused (sympetalous ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemism
Endemism is the state of a species being found only 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 also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or b ...

Southwest Australia
Southwest Australia is a biogeographic region in Western Australia. It includes the Mediterranean-climate area of southwestern Australia, which is home to a diverse and distinctive flora and fauna. The region is also known as the Southwest Australia Global Diversity Hotspot. Geography The region includes the Mediterranean forests, woodlands, and scrub ecoregions of Western Australia. The region covers 356,717 km2, consisting of a broad coastal plain 20–120 kilometres wide, transitioning to gently undulating uplands made up of weathered granite, gneiss and laterite. Bluff Knoll in the Stirling Range is the highest peak in the region, at 1,099 metres (3,606 ft) elevation. Desert and xeric shrublands lie to the north and east across the centre of Australia, separating Southwest Australia from the other Mediterranean and humid-climate regions of the continent. Climate The region has a wet-winter, dry-summer Mediterranean climate, one of five such regions in the worl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sessility (botany)
In botany, sessility (meaning "sitting", in the sense of "resting on the surface") is a characteristic of plant organs such as flowers or leaves that have no stalk. Plant parts can also be described as subsessile, that is, not completely sessile. A sessile flower is one that lacks a pedicel (botany), pedicel (flower stalk). A flower that is not sessile is Pedicel (botany), pedicellate. For example, the genus ''Trillium'' is partitioned into multiple subgenera, the sessile-flowered trilliums (Trillium#Subgenus Sessilia, ''Trillium'' subgen. ''Sessilia'') and the pedicellate-flowered trilliums. The term "sessility" is also used in mycology to describe a fungal sporocarp (fungi), fruit body that is attached to or seated directly on the surface of the substrate (biology), substrate, lacking a supporting stipe (mycology), stipe or pedicel (botany), pedicel.

Bract
In botany, a bract is a modified or specialized leaf, associated with a reproductive structure such as a flower, inflorescence axis or cone scale. Bracts are usually different from foliage leaves in size, color, shape or texture. They also look different from the parts of the flower, such as the petals or sepals. A plant having bracts is referred to as bracteate or bracteolate, while one that lacks them is referred to as ebracteate or ebracteolate. Variants Some bracts are brightly coloured which aid in the attraction of pollinators, either together with the perianth or instead of it. Examples of this type of bract include those of '' Euphorbia pulcherrima'' (poinsettia) and '' Bougainvillea'': both of these have large colourful bracts surrounding much smaller, less colourful flowers. In grasses, each floret (flower) is enclosed in a pair of papery bracts, called the lemma (lower bract) and palea (upper bract), while each spikelet (group of florets) has a further pair o ...

Ferdinand Von Mueller
Baron Sir Ferdinand Jacob Heinrich von Mueller, (; 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 in 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 Bertha had been advi ...

George Maxwell
George Maxwell (1804–1880) was a professional collector of plants and insects in Southwest Australia. The botanical specimens he obtained were used to make formal descriptions of the region's plant species. Biography Maxwell was born in England in 1804 and moved to Western Australia in 1840 to settle at King George Sound, remaining there until his death at Middleton Beach in 1880. He occupied himself a number of activities, selling curios and offering to guide visitors to the port. He began collecting plants and insects of the region, assisting the botanist James Drummond (botanist), James Drummond in 1846. The collections he made, in the company of Drummond and Ferdinand von Mueller, would provide type specimens for the publication of scientific descriptions. Maxwell's collections are now preserved in Australian herbarium, his contribution to the botanical knowledge of the region and ''Flora Australiensis'' was noted by Mueller in ''the Gardeners' Chronicle''; Only two years ag ...
