Pityrodia Jamesii
''Pityrodia jamesii'' is a flowering plant in the mint family Lamiaceae and is endemic to Arnhem Land in the Northern Territory, Australia. It is a spreading shrub with hairy, yellowish brown stems, sticky, hairy, egg-shaped to lance-shaped leaves and white, bell-like flowers. Description ''Pityrodia jamesii'' is a spreading, hairy shrub which grows to a height of about , its branches covered with yellowish hairs. The leaves are lance-shaped to egg-shaped, sticky when young, mostly long and wide with the edges rolled under. They are crowded near the ends of the branches and are hairy and glandular with raised veins on the underside. The flowers are arranged in the upper leaf axils with bracts and smaller bracteoles. The five sepals are joined at the base and form a bell-shaped tube that is glandular and hairy on the outside and glabrous inside. The petals are white long and joined for about half their length to form a bell shaped tube with five lobes on the end. The lower thre ...

Sepal
A sepal () is a part of the flower of angiosperms (flowering plants). Usually green, sepals typically function as protection for the flower in bud, and often as support for the petals when in bloom., p. 106 The term ''sepalum'' was coined by Noël Martin Joseph de Necker in 1790, and derived . Collectively the sepals are called the calyx (plural calyces), the outermost whorl of parts that form a flower. The word ''calyx'' was adopted from the Latin ,Jackson, Benjamin, Daydon; A Glossary of Botanic Terms with their Derivation and Accent; Published by Gerald Duckworth & Co. London, 4th ed 1928 not to be confused with 'cup, goblet'. ''Calyx'' is derived from Greek 'bud, calyx, husk, wrapping' ( Sanskrit 'bud'), while is derived from Greek 'cup, goblet', and the words have been used interchangeably in botanical Latin. After flowering, most plants have no more use for the calyx which withers or becomes vestigial. Some plants retain a thorny calyx, either dried or live, as ...

Pityrodia
''Pityrodia'' is a genus of flowering plants in the mint family, Lamiaceae and is endemic to Australia, most species occurring in Western Australia, a few in the Northern Territory and one in Queensland. Plants in this genus are shrubs with five petals joined to form a tube-shaped flower with four stamens of unequal lengths. Description Plants in the genus ''Pityrodia'' are evergreen shrubs with erect, usually cylindrical branches. The leaves are simple, net-veined and their bases partly wrap around the stem (decurrent). The flowers may occur singly or in groups and exhibit left-right symmetry. There are 5 sepals which are joined at their bases and 5 petals joined to form a tube. The tube may have 5, unequally sized lobes at the tip or two "lips" - the upper lip having two lobes and the lower one three. There are four stamens with one pair longer than the other. The fruit is a drupe containing up to four seeds. Taxonomy and naming The genus was first described by Robert ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Territory Parks And Wildlife Conservation Act 2000
A territory is an area of land, sea, or space, particularly belonging or connected to a country, person, or animal. In international relations, international politics, a territory is usually either the total area from which a state may extract power resources or an administrative division is usually an area that is under the jurisdiction of a sovereign state. As a subdivision a territory is in most country, countries an organized division of an area that is controlled by a country but is not formally developed into, or incorporated into, a politics, political unit of the country that is of equal status to other political units that may often be referred to by words such as "provinces" or "regions" or "states". In its narrower sense, it is "a geographic region, such as a colonial possession, that is dependent on an external government." Etymology The origins of the word "territory" begin with the Proto-Indo-European root ''ters'' ('to dry'). From this emerged the Latin word ...

Botanical Name
A botanical name is a formal scientific name conforming to the '' International Code of Nomenclature for algae, fungi, and plants'' (ICN) and, if it concerns a plant cultigen, the additional cultivar or Group epithets must conform to the ''International Code of Nomenclature for Cultivated Plants'' (ICNCP). The code of nomenclature covers "all organisms traditionally treated as algae, fungi, or plants, whether fossil or non-fossil, including blue-green algae ( Cyanobacteria), chytrids, oomycetes, slime moulds and photosynthetic protists with their taxonomically related non-photosynthetic groups (but excluding Microsporidia)." The purpose of a formal name is to have a single name that is accepted and used worldwide for a particular plant or plant group. For example, the botanical name ''Bellis perennis'' denotes a plant species which is native to most of the countries of Europe and the Middle East, where it has accumulated various names in many languages. Later, the plant was intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1948 American-Australian Scientific Expedition To Arnhem Land
In February 1948, a team of Australian and American researchers and support staff came together in northern Australia to begin, what was then, one of the largest scientific expeditions ever to have taken place in Australia—the American-Australian Scientific Expedition to Arnhem Land (also known as the Arnhem Land Expedition). Today it remains one of the most significant, most ambitious and least understood expeditions ever mounted. Seventeen men and women journeyed across the remote region known as Arnhem Land in northern Australia for nine months. From varying disciplinary perspectives, and under the guidance of expedition leader Charles Mountford, they investigated the Indigenous populations and the environment of Arnhem Land. In addition to an ethnographer, archaeologist, photographer, and filmmaker, the expedition included a botanist, a mammalogist, an ichthyologist, an ornithologist, and a team of medical and nutritional scientists. Their first base camp was Groote Eylandt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gunbalanya, Northern Territory
Gunbalanya (also spelt Kunbarlanja, and historically referred to as Oenpelli) is an Aboriginal Australian town in west Arnhem Land in the Northern Territory of Australia, about east of Darwin. The main language spoken in the community is Kunwinjku (a dialect of Bininj Kunwok). At the 2021 Australian census, Gunbalanya had a population of 1,177. Only accessible by air in the wet season, Gunbalanya is known for its Aboriginal art, in particular rock art and bark painting. It has a range of services, including a police station, school and community arts centre, Injalak Arts. It is the nearest town to the Awunbarna, also known as Mount Borradaile, an Aboriginal sacred site and the location of significant Indigenous Australian rock art. Etymology and history The area now known as Gunbalanya was originally called "Uwunbarlany" by Erre-speaking people, who were its original inhabitants. Oenpelli was the way Paddy Cahill (1863–1923), the founder of the original cattle station in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stamen
The stamen (plural ''stamina'' or ''stamens'') is the pollen-producing reproductive organ of a flower. Collectively the stamens form the androecium., p. 10 Morphology and terminology A stamen typically consists of a stalk called the filament and an anther which contains ''sporangium, microsporangia''. Most commonly anthers are two-lobed and are attached to the filament either at the base or in the middle area of the anther. The sterile tissue between the lobes is called the connective, an extension of the filament containing conducting strands. It can be seen as an extension on the dorsal side of the anther. A pollen grain develops from a microspore in the microsporangium and contains the male gametophyte. The stamens in a flower are collectively called the androecium. The androecium can consist of as few as one-half stamen (i.e. a single locule) as in ''Canna (plant), Canna'' species or as many as 3,482 stamens which have been counted in the saguaro (''Carnegiea gigantea'' ...

Glabrous
Glabrousness (from the Latin ''glaber'' meaning "bald", "hairless", "shaved", "smooth") is the technical term for a lack of hair, down, setae, trichomes or other such covering. A glabrous surface may be a natural characteristic of all or part of a plant or animal, or be due to loss because of a physical condition, such as alopecia universalis in humans, which causes hair to fall out or not regrow. In botany Glabrousness or otherwise, of leaves, stems, and fruit is a feature commonly mentioned in plant keys; in botany and mycology, a ''glabrous'' morphological feature is one that is smooth and may be glossy. It has no bristles or hair-like structures such as trichomes. In anything like the zoological sense, no plants or fungi have hair or wool, although some structures may resemble such materials. The term "glabrous" strictly applies only to features that lack trichomes at all times. When an organ bears trichomes at first, but loses them with age, the term used is ''glabrescent ...

Bract
In botany, a bract is a modified or specialized leaf, especially one associated with a reproductive structure such as a flower, inflorescence axis or cone scale. Bracts are usually different from foliage leaves. They may be smaller, larger, or of a different color, shape, or texture. Typically, 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 and ebracteolate, without bracts. Variants Some bracts are brightly-coloured and serve the function of attracting 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 p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atlas Of Living Australia
The Atlas of Living Australia (ALA) is an online repository of information about Australian plants, animals, and fungi. Development started in 2006. The Commonwealth Scientific and Industrial Research Organisation (CSIRO) is an organisation significantly involved in the development of the ALA. The Atlas of Living Australia is the Australian node of the Global Biodiversity Information Facility. The ALA is being used to help assess suitability of revegetation projects by determining species vulnerability to climatic and atmospheric change. The Atlas of Living Australia is hosted by CSIRO and supported by the National Collaborative Research Infrastructure Strategy.Atlas of Living Australia: Who we are. Retrieved 11 April 2019.
